Smashing Security, episode 377: An Unhealthy Data Dump. Ransomware, ransomware surveillance, and a Cheetah Sues Apple with Carole Theriault and Graham Cluley.

Hello, hello, and welcome to Smashing Security episode 377. My name's Graham Cluley.
CAROLE THERIAULT
And I'm Carole Theriault.
GRAHAM CLULEY
And Carole, we're joined this week by a special guest, someone who's been on the show before, the newly anointed at the European Security Blogger Awards. It is Lianne Potter.

You won an award, didn't you, Lianne? Hello.
LIANNE POTTER
I did. The newcomer, which sounds like a really fun Western title. But yeah, and join the pantheons now of Smashing Security. So, you know, all bow down for Compromising Positions.
GRAHAM CLULEY
So that's the name of your podcast, isn't it?
LIANNE POTTER
It is indeed. And for the love of George Michael, please do not just Google Compromising Positions. Google Compromising Positions cybersecurity podcast. I cannot be held responsible.
CAROLE THERIAULT
Let's thank this week's wonderful sponsors: 1Password, Smashing Security, and Vanta. It's their support that helps us give you this show for free.

Now, coming up on today's show, Graham, what do you got?
GRAHAM CLULEY
I'm going to be talking about hackers and haggis.
LIANNE POTTER
Okay.
CAROLE THERIAULT
What about you, Lianne?
LIANNE POTTER
I'm going to be talking about how Amazon have been watching us as we go on our merry way aboard this nation's disastrous infrastructure, the trains.
CAROLE THERIAULT
And I'm going to be touching upon who to blame when things go unpredictably awry. Plus, we have a featured interview with Abhishek Agrawal.

He is the co-founder and CEO of Material Security. We talk about email threats today and common misconceptions. All this and much more coming up on this episode of Smashing Security.
GRAHAM CLULEY
Now, chums, chums, or should I say lads and lassies, buckle up. Because I'm going to be taking you on a wee trip north of the border to the lands of—
CAROLE THERIAULT
Oh God, no.
GRAHAM CLULEY
Kilts, whisky, and Ockey the New. Yes, I'm talking about Birmingham, of course. That's where we're heading. No, a little bit further north than that.

I can't pull the wool over your eyes because you can hear the bagpipes in the distance.

We are, of course, in beautiful bonnie Scotland, where the sheep's stomachs are considered a delicacy. So gather round, ye brave souls. Pack your raincoats.
CAROLE THERIAULT
Are sheep stomachs used in bagpipes?
GRAHAM CLULEY
Well, that's a very interesting question. I'm pretty sure sheep stomachs are somehow involved in the haggis, aren't they?
LIANNE POTTER
Yeah, I think— Well, you can get something called a bagpipe lung, can't you? So I think they're pretty grim inside those bagpipes. They get really mouldy.

So I think if it was made out of sheep stomach as well.
GRAHAM CLULEY
Yeah. Yeah.
LIANNE POTTER
There's been a lot of recalls in the UK about sandwiches and things, I think. Yeah. You need to be careful about that sort of thing.
GRAHAM CLULEY
Basically, bagpipes are a sheep's stomach just sort of prodded with a few recorders and things, isn't it? That's what they've got.
CAROLE THERIAULT
I bought you one once.
GRAHAM CLULEY
Exactly. I have owned a set of bagpipes. I enjoyed playing them. I have played them in public. I played them, in fact, at InfoSec one year, many, many years ago.
LIANNE POTTER
It's a shame that we don't do ASBOs in this country anymore.
GRAHAM CLULEY
They ended up punctured.
CAROLE THERIAULT
Ouch.
GRAHAM CLULEY
But yes, that was it. Nevermore, nevermore. But don't worry about that, because I want to tell you the terrible tale of what's been going down in Dumfries and Galloway.
LIANNE POTTER
Lovely parts of the world.
GRAHAM CLULEY
Have you been there, Lianne?
LIANNE POTTER
I have, I have. Very, very pretty.
GRAHAM CLULEY
It's very pretty, I think. There's all sort of spooky castles and lakes and beaches and all sorts of loveliness.

Well, the National Health Service systems, the IT systems up there, they were hit by the Inc Ransom Group in February, who alleged that they had stolen huge amounts of patient and staff data, 3 terabytes worth, they said that they had taken, was taken under the nose of the NHS Scotland up there.

And to back up their claim, Inc Ransom published what they called a proof pack on the dark web. So, I think it was the confidential information of about 6 patients.

They said, "We've got a lot more than this, but we've got 6 patients' worth of data." But they dangled it. They said, "This is what we've got.

We will release more unless you pay the ransom." Oh, right, a kind of teaser saying, "Here's a little bit of the stuff that you might expect, and we have 3 terabytes worth." Yeah, it's a bit if you kidnap you know, a relative of John Paul Getty, you cut off their ear and send that to the family and say, look, we've clearly got him.

Although, how would you know?
CAROLE THERIAULT
I don't even know who John Paul Getty is.
GRAHAM CLULEY
Oh, he was a billionaire back in the '70s, '80s.
CAROLE THERIAULT
Why would I know that?
GRAHAM CLULEY
Well, just, you know.
CAROLE THERIAULT
Knowledge?
GRAHAM CLULEY
Just general knowledge.
CAROLE THERIAULT
Did you know, Lianne?
LIANNE POTTER
I only knew because there was a film that they tried to make recently, and I believe it was supposed to star Kevin Spacey, and then it got—
CAROLE THERIAULT
Oh, aha.
LIANNE POTTER
It got canned for reasons that we won't go into. And then they remade it entirely again. So it cost the studio millions and millions and millions.
GRAHAM CLULEY
Oh.
LIANNE POTTER
And it flopped. So that was worth it.
GRAHAM CLULEY
Oh dear. Anyway, so what the ransomware groups do is sometimes they release a little bit of the data. They say, "Look, obviously we've got a lot more than this.

We've got a lot more than this, but you can check." and you'll be able to see that this is data related to some of your patients in this case.

And if you want to stump up the cash, then we won't release the millions and millions of other pieces of data as well. So they asked for a ransom.

The news became public knowledge, I think the following month, the media were all over it. One headline I read said, Cyber expert urges against panic over NHS data leak.

And I thought those were very wise words for the expert to urge against panic.

I sometimes wonder why they contact experts, the media, cybersecurity experts, because it's isn't that the blinding, bleeding obvious?

It's to say, well, I'll tell you what I suggest. I suggest you don't panic. It's you know, Corporal Jones used to advise that in Dad's Army. He was always saying, don't panic as well.
CAROLE THERIAULT
Another archaic reference. Okay.
LIANNE POTTER
Indeed.
GRAHAM CLULEY
John Paul Getty. That's me. You can see what era I'm from.
LIANNE POTTER
Not mine.
GRAHAM CLULEY
No. Anyway, so they didn't pay up, right? The NHS got them. They refused to pay the ransom.
CAROLE THERIAULT
Okay.

So they're saying, "No, this is not good." And this is something we advise often on this show, that we'd prefer if people didn't just kind of pay up and stay quiet and stay shut.
GRAHAM CLULEY
But I wonder how they make that decision, right?
LIANNE POTTER
Maybe they looked through the taster and they were just like, "No one cares about Bernie's gout. Nobody's interested in Hamish's warts."
CAROLE THERIAULT
Muriel only has weeks to live. It'll be fine.
GRAHAM CLULEY
They should have asked Hamish and Bernie how they feel about it. Shouldn't they ask the opinion of the people whose data is at risk of being exposed?
CAROLE THERIAULT
I think they'd mostly say no. I would prefer not.
LIANNE POTTER
Yeah, I don't want people to know about my hemorrhoids.
GRAHAM CLULEY
Couldn't they have emailed everyone and said, look, here's the information they've got. They know about your warts, about your halitosis.
LIANNE POTTER
Literally warts and all.
GRAHAM CLULEY
Erectile dysfunction.

I mean, they could have had maybe a whip around of everyone in Dumfries and Galloway and said, "Look, if you stump together £5, we can probably pay the ransom." They didn't even think of that.

Anyway, they refused to pay. And of course, the hackers released everything. They released everything. And that's pretty bad because a data leak like this—
CAROLE THERIAULT
So they do that for free because they didn't get their cash, just as a vendetta.
GRAHAM CLULEY
Yes.
CAROLE THERIAULT
It's not enough that they steal it. They have to also make it public for free for everyone. Or do they make it public for sale?
GRAHAM CLULEY
Well, they published it on their website so anyone could go and download it. And of course, commercially for them, it does send a very clear message to future victims.

We will actually carry out our threat. So that's why they do release it.
LIANNE POTTER
If we're talking about the commerciality of things like ransomware and stuff like that, why don't they have payment plans instead? To me, that would be more commercially viable.

Instead of just going, oh, I'm going to spit my dummy out and release the data. Let's put you on a little payment plan here.

If you don't want to pay the full amount, I know you're hard up, NHS, lately. Let's put it on layaway for you.
GRAHAM CLULEY
If you stop paying, something bad might happen. Anyway, could be embarrassing, this data leaking, because it claimed to have all kinds of information. For instance, it had X-rays.

Can you imagine how embarrassing X-rays can be? Have you ever seen your own X-rays?
CAROLE THERIAULT
I don't think X-rays would be that embarrassing.
GRAHAM CLULEY
Well, you haven't got any clothes on in an X-ray. It could be embarrassing.
CAROLE THERIAULT
You don't normally have skin in an X-ray either. It's just bones.
GRAHAM CLULEY
It's interesting that we're more embarrassed about our skin than what's inside our bodies, isn't it?
CAROLE THERIAULT
This is a weird episode, I gotta say. I just don't even know where your brain's going.
GRAHAM CLULEY
What if an X-ray revealed something inside your body which you didn't want revealed to the general public?
CAROLE THERIAULT
Like a tampon?
GRAHAM CLULEY
Oh my God. No, I wasn't thinking anything like that. I was thinking, I don't know.
CAROLE THERIAULT
The outrage.
GRAHAM CLULEY
A garden rake or something like that. Who knows? A toothbrush, a piece of Lego. I don't know. It could be very humiliating.

But also the other data which maybe was now in the hands of criminals was letters from consultants to patients, which could be, you know, about their embarrassing wart or condition.
CAROLE THERIAULT
I think the word's personal, private stuff.
GRAHAM CLULEY
Private.
CAROLE THERIAULT
Right?
GRAHAM CLULEY
Patient complaints. So if you make a complaint against a surgeon or a consultant, internal, external information.

So there's a potential for this to become public, potential for extortion maybe, or just simple embarrassment.

Things that you don't want your loved ones or your workplace or your friends knowing, or you don't want someone to set up a searchable database.
CAROLE THERIAULT
So you think this NHS group should have paid? That's what it sounds like.
GRAHAM CLULEY
Well, I'm just saying it's a complicated decision.
CAROLE THERIAULT
Oh, okay.
LIANNE POTTER
It is.
GRAHAM CLULEY
You're sort of stuck between a rock and a hard place.
LIANNE POTTER
A rock and a gallbladder, I don't know.
GRAHAM CLULEY
But seriously, some of the data which was exposed was a concern. For instance, there were records related to the mental health of children and teenagers.
LIANNE POTTER
That's not good.
GRAHAM CLULEY
Not good. Not good.

And we've seen attacks like that before where people have actually been approached after their medical information about their mental health has been exposed, and the ransom demand be made not only to the NHS or that medical body, but also to the patients as well.
CAROLE THERIAULT
The ransom gang does not win hearts and minds with this, though. I don't think most people would be thinking, yeah, really cool. You stole from a hospital.
LIANNE POTTER
Come here to do a job. I don't come here to be liked. Is that what they— that's my mantra.
GRAHAM CLULEY
So this is why Dumfries and Galloway NHS are now writing to every household in the area.
LIANNE POTTER
All 15 of them.
GRAHAM CLULEY
Well, I did— I've done my research. Apparently, it's around about 150,000 people.
CAROLE THERIAULT
Well, they're not handwritten. Okay.
GRAHAM CLULEY
It's like it's an error.
LIANNE POTTER
I'd like to think they were handwritten. That'd be good.
GRAHAM CLULEY
That would be good. Or if they had to sign them manually, that'd be fantastic. But they've now sent them this letter saying about the data that's been published, the risks.

There was also some advice about not to click on links in emails from people they didn't know or companies they didn't know.

And don't provide any information to people you don't know who contact you on the phone or via social media.

And you can go and read the letter that D&G have— That's not Dolce Gabbana, by the way. That's Dumfries Galloway. Very different things. Very different things.

And they've even got an easy-read version. So clearly they're recognising that some of their patients may not be—
CAROLE THERIAULT
Able to increase the font?
LIANNE POTTER
Is that because they read it in the dumped data leak? That, "Oh yeah, Dave can't see very well." Is that where they got that information from?
GRAHAM CLULEY
Or it's not just the size of the font, but it's shorter paragraphs. Nice icons. They've tried to make it a bit friendlier.

I think it's for people who maybe find reading lots of paragraphs a bit more complicated and challenging.
CAROLE THERIAULT
Right, right, right.
GRAHAM CLULEY
There's a dedicated helpline which you can ring up, and they even say if you see anything suspicious, call the police on 101 and report it. So dial 101 to get in touch with them.
CAROLE THERIAULT
Well, good for them. I mean, that seems like, you know, they're doing all the right things.
LIANNE POTTER
It's the best you can do in that situation.
GRAHAM CLULEY
But it's difficult, isn't it?

When you write to everybody saying that there's been a data breach and to look out for it, maybe that actually makes it easier for the scammers and identity thieves to exploit the situation to call up people and say, "You remember that letter you got the other day?

Well, I'm calling about that, or I need you to go to this website to claim your compensation." You can see that there may be other attacks in the wake of this.
CAROLE THERIAULT
Yeah, but if they did nothing, they also have all the information so they could email them and go, "Guess what? A cyberattack happened.

We're going to call you the next few days to ask for information to repopulate or do anything else."
GRAHAM CLULEY
Oh, the criminals could, you mean? Yes, I see.
CAROLE THERIAULT
Yes. Anything could be—no matter what they did, there's an extra risk after this happens. That's all I'm saying.
GRAHAM CLULEY
So you're stuck once again between a rock and Lianne's hard place. What did she say?
LIANNE POTTER
Gallbladder.
GRAHAM CLULEY
Oh, the pain. Lianne, what do you have for us this week?
LIANNE POTTER
Well, this week I've got something quite an out-and-out cyber incident, but I'd get your opinion on it about what it means for the cybersecurity industry.

So when in 1983 Rockwell explained he always feels somebody's watching him and he has no privacy, whoa, he wasn't far off. And now we're seeing that today.

So turns out Amazon have been watching us for the last two years as we go upon our merry way on the trains.

Now imagine this—you're on a train station, you're minding your own business, you're waiting for the train home, and then suddenly you notice that the CCTV camera is swerving towards you and you think, "Oh, it's just normal security, right?" But little did you know that that camera is actually a smart CCTV camera pumped to the eyeballs with AI surveillance stuff.

And so apparently for the last two years, and we've only found out about this because an organisation called Smashing Security did a request for information.
CAROLE THERIAULT
Mm-hmm.
LIANNE POTTER
They've been doing a trial on all of us monitoring crowds as we wait for our trains, not just if people are up to no good or anything that, but also trying to guess our age. Cheeky.

Trying to know what gender we are.
GRAHAM CLULEY
Cheeky.
LIANNE POTTER
Indeed. But also our moods as well. So deducing if we're happy, sad, or angry. And I think if anyone has had the pleasure of using UK trains lately, it's probably the last two.

I don't think I've ever been happy on a train in a very long time here.

But my question to you—so one, we wouldn't have known about this unless this organisation did a request for information.

And obviously, you know, Network Rail said they take privacy and security very seriously, of course, so that's okay then.

But what I would to ask you is now as cybersecurity professionals, as we enter this—everything's got an AI attachment to it—how do we keep up in this?

And where does this sort of ethics and morals lie in us helping organizations protect this stuff?

'Cause our organizations that we work in are gonna make us do stuff this, but where do we actually come in on this conversation and say, "Hey, I'm not quite happy with actually storing all this data because of the potential consequences if we lose this stuff." Not just going beyond normal data privacy stuff, which, you know, hopefully most of our organizations look after, but then what if that falls into the wrong hands?
ABHISHEK AGRAWAL
Yeah.
LIANNE POTTER
And, you know, potential misuse and things that.
CAROLE THERIAULT
It is spooky. It makes me think of this case in the States a few years back where there were these facial recognition cameras in malls.
GRAHAM CLULEY
Yes.
CAROLE THERIAULT
And the idea was to detect any immigrants that had not gone through the proper channels. So that's what's kind of scary about this.

I'm guessing, okay, and tell me if you know or if I'm completely off-piste here, but I'm guessing Amazon made a deal with the train networks to say, here's the deal and it's less money than you'd pay elsewhere, selling all the benefits.

But actually, do they get to harvest the information as well or does it stay within the UK train?
LIANNE POTTER
Well, it's not clear on the article itself and then the kind of request, you know, who knows, they could be just going, oh well, we could sell a lot of coffee, you know, travel coffee cups there, Amazon, or what other things could we sell, you know, more iPads and things to keep people entertained, better headphones and things.

I don't know, I'm just speculating where it could be useful. But what I do know is this is happening so much now, this lack of consent or even a discussion.

So yes, you know, I'm sure most of us would probably say there is actually positive benefits for them, keeping an eye out for people doing wrong things trespassing on rail tracks and things.

And, you know, not to go too dark, but, you know, people do commit suicide on the trains, and spotting that kind of emotional change will be very useful.

But my worry is we're constantly making these kind of concessions, and where does it stop?
CAROLE THERIAULT
Well, I'm not making the concessions. I don't even know this is happening, right?

The general public doesn't know this is happening until someone reveals it through an information request.
GRAHAM CLULEY
Normally they have a little sign up, don't they, in very small font somewhere on the wall saying, just so you know, by being here, you agree to being on CCTV and maybe we're scoring you.
CAROLE THERIAULT
But what's stopping a restaurant doing it, for example?

What if all Nando's right across the UK started putting AI powers just to see, detect emotions and see how happy their customers are, right?
GRAHAM CLULEY
And then you'd just be bitching to your fellow person, complaining about...

You're less likely to commit suicide or something in a Nando's than you are suffering the British rail system.
CAROLE THERIAULT
Have you eaten at Nando's?
GRAHAM CLULEY
I have actually. I have only eaten once in about— it was about 3 weeks ago.
LIANNE POTTER
Oh, so it's fresh in your mind. It is fresh in my mind. And how was your mental health?
GRAHAM CLULEY
I was fine, thank you very much.
LIANNE POTTER
Excellent. I had a salad-y sort of thing. It was alright. The next few stories, Nando's have AI surveillance. Yeah, because Graham said it was fine.
GRAHAM CLULEY
I was with some young people at the time who possibly, you know—
CAROLE THERIAULT
What, in their 40s?
GRAHAM CLULEY
More frequent visitors to Nando's than myself. But I mean, there are obviously legitimate reasons for doing this. Yes, understandable reasons, you know.
CAROLE THERIAULT
AI-powered cameras.
GRAHAM CLULEY
The people who own the stations, they're not doing this because they've got anything nefarious in mind.

I suspect that they're doing this because they're doing it for people's safety and protection.

The worry will be, of course, as you were suggesting, Carole, that what's Amazon going to do with all of this data? How could it use it?

And of course, at what point does law enforcement get involved and think, oh, we've got access to this?

And already in the United Kingdom, we have a huge number of CCTV cameras watching us everywhere we go. We're one of the most surveilled states in the world, aren't we?
LIANNE POTTER
Yeah, absolutely.
CAROLE THERIAULT
I know we're surveilled, but I don't know how we fit in with everyone.
LIANNE POTTER
Yeah, I think we're not— I think, isn't China known as probably the most surveilled state? I think we're really close, not far behind from that, actually.
GRAHAM CLULEY
Wow.
CAROLE THERIAULT
Bucket hats a-go-go, I think, right?
LIANNE POTTER
So yeah, so while there is definitely benefits for AI surveillance, like improving safety, you have to balance it with privacy concerns.

So all I can say to you really, I don't have an answer, but you know, next time you're at the train station remember just to give the cameras your best smile.
GRAHAM CLULEY
Would you consider wearing a balaclava?
LIANNE POTTER
Well, we've not had much of a summer, so maybe, yeah. Yeah.
GRAHAM CLULEY
Fair enough. Carole, what have you got for us this week?
CAROLE THERIAULT
So, this story is thanks to friend of the show, Anna Brading, who sent it over to me. So, this story is kind of a twofer. You know what I mean by twofer?
LIANNE POTTER
Mm-hmm.
CAROLE THERIAULT
Well, yeah, so it can be used here on Smashing Security, but it also could be used on my other podcast, Sticky Pickles, which is focused on dilemmas.
LIANNE POTTER
Very good.
GRAHAM CLULEY
Always promoting your other podcasts.
CAROLE THERIAULT
So Lianne, Graham, pay attention because there's going to be a what-do-you-do-now moment for you to ponder, okay?
LIANNE POTTER
Okay.
GRAHAM CLULEY
Okay. All right. I love this. Yeah, good.
CAROLE THERIAULT
Okay. So I'm introducing you to Richard. Richard's a married guy living in the UK.
GRAHAM CLULEY
Right.
CAROLE THERIAULT
Now he's been married for a while, and apparently happily so, right?

But he must have hit a bumpy road of sorts in Marriageville, because for a time, things must have not been going so great.

Like, so not great that Richard decided to secretly start stepping out to take advantage of one of the world's oldest professions.
GRAHAM CLULEY
Oh, a bookie's?
CAROLE THERIAULT
No, not whittling either. Right. Prostitution.
GRAHAM CLULEY
Okay. Ding dong.
CAROLE THERIAULT
So, Richard, with his trusty iPhone, starts messaging some ladies of the night, if I can use that term.
LIANNE POTTER
I always think they're vampires when they get referred to as ladies of the night.
GRAHAM CLULEY
I know.
CAROLE THERIAULT
Maybe they are. Maybe some are. That'd be so cool.
LIANNE POTTER
I think that's cool and also weird.
GRAHAM CLULEY
Yeah.
CAROLE THERIAULT
But this is all, of course, on the down low, right? Wife is not to find out.

So, to keep his missives to the ladies, mistresses of the street, whoa, he deletes the messages on his phone so she can't see them. So all good, all good.

You know, he's having secret sexy time messages and trysts, and his wife is none the wiser.
GRAHAM CLULEY
Yeah, when you say all good, not really that good, to be honest.
CAROLE THERIAULT
But well, good for him. He's thinking this is what he wants to do. He's stepping out and he's not leaving any tracks and no breadcrumbs, no breadcrumbs.

Until, until, until his wife opens iMessages on the home iMac. And there is a veritable waterfall of deleted messages to prostitutes.

And they tumble down the page revealing that darling Richard has had long periods of infidelity.

Then these, of course, are the messages he believed he had deleted and wiped for good. Right?
LIANNE POTTER
Busted.
ABHISHEK AGRAWAL
Busted.
CAROLE THERIAULT
So what do you do now? Okay, you're first. You're Richard's wife. What do you do? What do you do?
GRAHAM CLULEY
Change the locks?
CAROLE THERIAULT
Kill him?
LIANNE POTTER
I think I would screenshot them. Screenshot them just in case they get deleted again.
GRAHAM CLULEY
Oh God, that's quick thinking.
CAROLE THERIAULT
Yeah. Oh, that's smart. See, cyber professional. Cyber professional. Yeah, very good. Well, you know, this basically led Richard's wife to file for divorce. I mean, no real surprise.

And she did that within a month?
GRAHAM CLULEY
Yes.
CAROLE THERIAULT
Of all this happening? But I'm guessing that the divorce process was not all warm and fuzzy. You know, these things rarely are.
LIANNE POTTER
Yeah.
CAROLE THERIAULT
But Richard not only say he lost upwards of £5 million, so, you know, $6 million and change.
LIANNE POTTER
Whoa, how much did he have to start with?
CAROLE THERIAULT
Right? Who knows? In the divorce. But also he says that his health has taken a turn because of the divorce. He's getting panic attacks.

In order to reduce them, he's taking strong beta blockers, fearing a heart attack.
LIANNE POTTER
I thought you were gonna say he had venereal disease. But yeah.
CAROLE THERIAULT
So Richard's now feeling very poor. He's feeling down in the dumps. He's trying to circumnavigate panic attacks. And if you are Richard, what do you do now? What do you do now?
GRAHAM CLULEY
Go on a dating site, maybe?
CAROLE THERIAULT
Find yourself a really rich mama?
GRAHAM CLULEY
Get my haircuts and a change of wardrobe, maybe?
CAROLE THERIAULT
Dye your hair?
GRAHAM CLULEY
Buy myself a convertible car, probably.
CAROLE THERIAULT
Brilliant. Yes. Like a hairdresser's car or something.
GRAHAM CLULEY
Yeah, something like that. Yeah.
CAROLE THERIAULT
Well, you know, you might want to get some money rolling in. Richard certainly does, because $5 million is a serious hit.
GRAHAM CLULEY
So how did he lose $5 million from getting divorced?
LIANNE POTTER
Good.
CAROLE THERIAULT
That is not clear. In my research, I have not. I did try and find that out because, you know, fascinating.

But he gets a lightning bolt of an idea, one of those brilliant, trifecta of everything aligning. Just sue Apple, right? Get Apple to refund the losses.

Yes, file a lawsuit, a class action lawsuit against Apple, because Apple is the entity that ruined his life. Not his philandering, Apple.

And yes, let's call upon London-based law firm Rosenblatt to arrange legal action against Apple.

And yes, let's go public to attract men in the same situation to go in with Richard on the suit.
LIANNE POTTER
I'd like to think that at some point, he was turning around and just going, "I don't wanna go away with two of it, one of those meddling tech companies." I've got a theory.
GRAHAM CLULEY
He's already lost $5 million or something. Is that right? £5 million.
CAROLE THERIAULT
£5 million, yeah.
GRAHAM CLULEY
£5 million, okay. It sounds to me like he's about to lose some more money, and he'll be giving it to his legal team. And he's probably not going to be getting the money back.

I'm just thinking that if he's hired this London law firm, Rosenblatt. Whatever.
LIANNE POTTER
Clance Guilderson.
GRAHAM CLULEY
To sue the megalith which is Apple, which will definitely have even more expensive lawyers working for it.
LIANNE POTTER
I'd love to think that Apple's legal team, when they got that letter through the door, was just a crank.
CAROLE THERIAULT
Okay, but listen, listen, listen, listen, okay?

One possibility for the lack of deletion across all the services may be down to the fact that the device was not linked to a central iCloud account.

So according to Apple support documents, if you use Messages in iCloud, deleting a message or conversation on your Mac deletes it from all your devices where Messages in iCloud is on.
GRAHAM CLULEY
So how did it show up on the other device then, if that wasn't linked?
CAROLE THERIAULT
Well, if the account is not linked to an iCloud account, deleting messages will only remove them from the local device and not the linked devices.

So you can link devices separately from using iCloud.
GRAHAM CLULEY
So he didn't read the flipping manual.
CAROLE THERIAULT
Well, yeah, who does? I'm just asking, right? So Rich reportedly says in The Times, if you were told a message is deleted, you are entitled to believe it's deleted.

Kind of a fair point, I think.
LIANNE POTTER
I think that's reasonable. Yeah.
CAROLE THERIAULT
Yeah. If the message had said these messages are deleted on this device, that would have been a clue, he says.

These messages are deleted on this device only would have been a much clearer indicator.
LIANNE POTTER
Hmm. Does he have a case? Did he get $5 million back?
CAROLE THERIAULT
Not yet. We don't know. He says it was a very brutal way for his wife to find out.
LIANNE POTTER
Oh, now he cares about her opinion. Okay. Right.
CAROLE THERIAULT
Well, he also reportedly believes that there could have been a chance of the marriage continuing had he been able to talk to her rationally.

But I guess it was difficult after she found out he was secretly stepping out with prostitutes.
GRAHAM CLULEY
Yeah, yeah, yeah.
CAROLE THERIAULT
Now, according to Apple Insider, who absolutely slated this man—
GRAHAM CLULEY
Maybe he should sue his wife for not being prepared to have a rational conversation with him about his use of prostitutes.
CAROLE THERIAULT
Oh, interesting.
LIANNE POTTER
Or maybe the prostitutes for being so tempting.
GRAHAM CLULEY
Yeah, maybe she can countersue saying, yeah, the prostitutes should be sued as well for advertising their goods.
CAROLE THERIAULT
Yes, because otherwise he would never have found them.
GRAHAM CLULEY
That's right.
CAROLE THERIAULT
So according to Apple Insider, there would have to be massive changes in UK law for Apple to get blamed or held liable for the inciting incident.

But according to lawyer Simon Walton of Rosenblatt, he says in many cases the iPhone informs the user that messages have been deleted, but as we have seen, this isn't true and is misleading because they are still found on other linked devices, something Apple doesn't tell its users, he added.
GRAHAM CLULEY
We shouldn't be listening to the lawyers at all because the lawyers don't give a damn. All the lawyers care about is that they're getting paid by their client.

Whatever crackpot they are, they don't care whether the person that they're representing is sane or not. They're just taking the cash.
CAROLE THERIAULT
It's interesting, a lot of media reports intimated that they were surprised that Rosenblatt took this case on, because it seems like a pretty clear non-winner.
GRAHAM CLULEY
I think it was the prostitutes who have been intimated with.
LIANNE POTTER
If Apple were to change the wording slightly right now, which I think they probably should—
CAROLE THERIAULT
I agree with you, yeah.
LIANNE POTTER
But if they did, would that be an admission that they were wrong? And so they can't.
CAROLE THERIAULT
I don't know. The world is so ugly. I don't know. I'm gonna end with a quote from Richard, okay? He says, quote, "We were very happily married and had been for over 20 years.

I think what has been a superb marriage has been thrown away for something which many men do." What? And some women do. But mainly men.

So to surmise, it is completely and utterly Apple's fault. And best of luck, Richard.
LIANNE POTTER
It's Richard who speaks for all men, apparently.
CAROLE THERIAULT
Yeah, Richard who speaks for mankind.
ABHISHEK AGRAWAL
Man, oh man.
GRAHAM CLULEY

In a perfect world, end users would only work on managed devices with IT-approved apps.

But every day, employees use personal devices and unapproved apps that aren't protected by MDM, IAM, or any other security tool.

There's a giant gap between the security tools we have and the way we actually work.

1Password calls it the Access Trust Gap, and they've also created the first-ever solution to fill it.

1Password Extended Access Management secures every sign-in for every app on every device.

It includes the password manager that you know and love, and the device trust solution you've probably heard of on this podcast, back when it was called Collide.

1Password Extended Access Management cares about user experience and privacy, which means it can go places other tools can't, personal and contractor devices.

It ensures that every device is known and healthy, and every login is protected.

So stop trying to ban BYOD or shadow IT and start protecting them with 1Password Extended Access Management. Check it out at 1password.com/smashing.

And thanks to 1Password for supporting the show. And welcome back, and you join us at our favorite part of the show, the part of the show that we call Pick of the Week.
CAROLE THERIAULT
Pick of the Week.
LIANNE POTTER
Pick of the Week.
GRAHAM CLULEY
Pick of the Week is the part of the show where everyone chooses something they like.

Could be a funny story, a book that they've read, a TV show, a movie, a record, a podcast, a website, or an app, whatever they wish. Doesn't have to be security-related necessarily.
CAROLE THERIAULT
Better not be.
GRAHAM CLULEY
Well, my pick of the week this week is not really security-related. It is techie and IT-related. I've been working on a top-secret project lately. Maybe I'll reveal it in a few weeks.

And I've been having to create a little website and set it up. And I've had a niggle. I've had a complexity in the setup of the website, and I was wondering what the problem was.

And it turned out to be— and anyone out there who's geeky and has tried to set up websites and email systems and the like will know those three terrifying letters: DNS.

And your DNS records, you know about that, don't you, Lianne?
LIANNE POTTER
I have got a website.
GRAHAM CLULEY
The question always is, why has this gone wrong? Could it possibly be DNS that has gone wrong? And the answer is always, yes, it is DNS. It's always, always a DNS problem.

Anytime Facebook or Twitter or anything like that goes down, chances are it's a DNS problem.
LIANNE POTTER
Pretty much.
GRAHAM CLULEY
It is just the flakiest thing imaginable that the whole internet is relying upon. So I came across a website as I was getting very, very frustrated with DNS entries.
CAROLE THERIAULT
That's unlike you, getting frustrated.
GRAHAM CLULEY
Yes, not like, yeah, exactly. Exactly. Well, I'm careful with how I vent my frustration. I'm not like Richard, but there is a website which I've been to called isitdns.com.

So if you're ever wondering whether it is DNS that's causing the problem or not, just go to isitdns.com. What it says is, yes, it is DNS, which is causing the problem.
LIANNE POTTER
Very nice. Very nice. It's a good answer.
GRAHAM CLULEY
It's very useful for you. Now, this particular website also sells some merchandise.

For instance, you can get a t-shirt which says, "If DNS had a face, I would punch it." There's another one which says in great big letters with an exclamation mark, "It wasn't DNS!" Oh yeah, it was.

And in smaller writing underneath it goes, "Laughing out loud. Just kidding. It was totally DNS." So it is DNS. I don't know if DNS should be my pick of the week. Is it DNS?

DNS is my pick of the week, but DNS itself is my nitpick of the week. Because I am very, very frustrated by DNS and how often it goes wrong. Lianne, what's your pick of the week?
LIANNE POTTER
So my pick of the week, I was deliberating about this, but I've decided since it's had a bit of a profound effect on me and I wasn't expecting it.

And I should preface this, the person I'm about to discuss, I am not actually a fan of this person. But I'll go into it.

So my pick of the week is an audiobook, and it's the audio version of Barbra Streisand's autobiography, My Name Is Barbra.

Now I say I'm not a fan, doesn't mean I don't like her, but you know, and I love Funny Girl, and you know, some of the songs are bangers and things like that, but I'm not a hardcore fan, at least not hardcore enough to listen to an audiobook that is 48 hours and 17 minutes long, right?
CAROLE THERIAULT
That sounds dreamy. Does she read it herself, or—
LIANNE POTTER
She reads it herself, right?
GRAHAM CLULEY
Oh my God, oh my God, I'm all overcome now. I love Barbra Streisand.
LIANNE POTTER
Well, I do now. I am totally besotted with her, absolutely besotted. It's been one of the nicest things I've been listening to over the past weeks. It is absolutely brilliant.

So I saw a review for it and people were saying it's brilliant, and I thought, oh, I'll just give it a go because I love a good audiobook. It's phenomenal.

It's funny, it's heartwarming.

And I tell you what, as I used to listen to it, I did listen to it on double speed because she actually sounds younger on double speed because she's getting on in her years now.
CAROLE THERIAULT
Double speed, like two times, literally?
GRAHAM CLULEY
Yeah.
LIANNE POTTER
And she sounds just like she did back in the '70s and '80s again. So, and plus it was 48 hours and 17 minutes.

I had to get through it somehow because I'd actually borrowed it from my local library online audio service. There you go.
CAROLE THERIAULT
Yeah, yeah.
LIANNE POTTER
So I didn't want to keep it all to myself when someone else could be listening to us, which is why I made the choice going double speed.

I absolutely miss her now she's gone out of my life, and I used to just walking around listening to her telling me things. It was so nice.

So it's brilliant, and I just can't say enough how amazing it is. But what was really nice was there was — she's interwoven actually her singing as well.

So if you're not familiar with her work, take it out of double speed because you're trying to get through 48 hours and 17 minutes of audiobook. Listen to her. It's fantastic.

And then put it back on double speed. But she also talks about the Streisand effect. So do you know what the Streisand effect is?
ABHISHEK AGRAWAL
Yes.
LIANNE POTTER
Yeah, well, yes, just in case you're listening.

So the Streisand effect is the — was pretty much an unintended consequence of Barbra Streisand's attempt to censor some information about her.

So what basically happened was, and she goes into detail in her book, was some photographer decided to take loads of pictures of houses that were on cliff faces about to fall into the ocean, basically.

And Barbra Streisand's house was one of them, and it was for environmental reasons. Create this book.

However, she was one of the only people they mentioned her by name, so they gave exact coordinates of where she lived.

And you know, obviously a massive breach of privacy, which we've been talking about all this episode really, haven't we?

So yeah, so the Barbra Streisand effect is basically she sued, and what happened is it went from 6 people seeing this image in a book to obviously being absolute massive news and everyone knows.

Yeah, yep, just really interesting to hear a perspective on it. So my pick of the week is Get Comfort I would say start making friends with Barbra Streisand.

I was very tempted afterwards. I was so moved by her book.

I was very tempted to write to her and say, "I'm not a fan, but I've really enjoyed your book." But then my other half said, "That's not a very nice thing to write to someone." But I meant it in good faith.

She's really converted me. I'm so interested. I'm going to go through all her film back catalog. Yeah, brilliant.
GRAHAM CLULEY
Oh, you should. You should. Barbra Streisand's great. The Way We Were. Have you seen The Way We Were?
LIANNE POTTER
I have seen The Way We Were. I love Funny Girl.
CAROLE THERIAULT
Funny Girl is great. Yeah, yeah.
GRAHAM CLULEY
Talk? Oh, she's so sexy. And what's up?
LIANNE POTTER
Well, if you're interested in that, she does go into quite a lot of detail. She is, I didn't realize the people she was connected with, I should say.

My, if you could see me, my glasses will be wiggling. But yeah, she's had quite the life, we'll put it that way.

But yeah, I miss Barbra every single day now that that audiobook has finished.
CAROLE THERIAULT
Oh, that's a beautiful pick of the week.
GRAHAM CLULEY
Well I may see if I can borrow it from my library as well. That sounds terrific.
LIANNE POTTER
It's brilliant.
CAROLE THERIAULT
Mm-hmm.
GRAHAM CLULEY
Fantastic. Carole, what's your pick of the week?
CAROLE THERIAULT
Well, weird, Leanne, because I also have a book, an audiobook. Mine is a memoir with the best title that I've seen this year, I'm Glad My Mom Died.

This is a 2022 dark comedic memoir by this former actress called Janine Jenna McCurdy. Have you heard of her?
LIANNE POTTER
No.
CAROLE THERIAULT
She's known for sitcoms, mostly kids' sitcoms. So one's called iCarly, Sam Cat, Malcolm in the Middle, you may have heard of.
LIANNE POTTER
Yeah, Malcolm in the Middle. Yeah.
CAROLE THERIAULT
That played here. Yeah, I hadn't really seen any of these, but I didn't know anything about Jennette McCurdy, but I really liked the title.

So when I saw it in my feed, I was like, I'm going to get that audiobook. Let's try it.

And it's great because she was a child actress and the whole book is about her going through that with her difficult relationship with her mother who was obviously in charge of her at the time.

So she started acting at age 6 and got talked into going to auditions by her mother at that time.

Apparently her mom's own acting aspirations were thwarted by her disapproving parents.
LIANNE POTTER
Oh no, not showbiz mom.
CAROLE THERIAULT
I want to give you the life I never had, that kind of thing. Yeah, Mom does not come off very good—Mommie Dearest not good.

Jennette was not allowed to shower on her own until her late teens because her mom had to do it to make sure she was really, really clean. Forced her into diets.

And despite winning all these awards for the sitcoms, she was a complete anorexic who leaned on alcohol way too much.

But despite all these shocking behind-the-scenes revelations, she's a really punchy writer with some great comedic moments that weave all these hardships together.

And it seems writing is very much her thing. She says of it in the book, performing feels inherently fake, writing feels inherently real.

Anyway, so if this sounds like your thing, check it out. I'm Glad My Mom Died by Jennette McCurdy. You can find it wherever you get your books or audiobooks from.

It is my pick of the week.
GRAHAM CLULEY
Now, Carole, you've been chatting to the folks at Material this week.
CAROLE THERIAULT
Yes, I have. Abhishek Agrawal, he's the co-founder and CEO of Material, and we talk about all things email and email security. Check it out.

So today on Smashing Security's featured interview, we are speaking with Material Security's co-founder and CEO, Abhishek Agrawal.

Now, Material Security are creators of a multi-layer detection and response toolkit for email.

And today, we're going to find out about email threats and find out what dangers they pose for organizations right now in 2024. So welcome to Smashing Security, Abhishek Agrawal.

A delight to have you here.
ABHISHEK AGRAWAL
Thank you for having me. I'm excited to be here.
CAROLE THERIAULT
Now, first, maybe we could start with getting to know you. What can you tell us about your background and what led you to co-found Material Security?
ABHISHEK AGRAWAL
Yeah, sure thing. So before founding this company, I was a very early PM at Dropbox. Where I actually wasn't on the security side.

I led data infrastructure groups, which powered a lot of Dropbox's internal monetization and experimentation efforts.

I also worked on search and a lot of the different consumer surfaces there. And my background before that is I was at Microsoft Research working on productivity-related incubations.

So really background was in product and engineering more focused on the productivity side. And this company was kind of a new foray into security.

And at Dropbox, we had definitely some exposure to the internal security team that led to some of the early ideas here.

But my background's primarily on the productivity side before this company.
CAROLE THERIAULT
Right. And then, so you founded Material Security in 2017?
ABHISHEK AGRAWAL
That's right. Yep.
CAROLE THERIAULT
Yeah. And what led to that? So what was the niggling thing that you thought needed to be resolved? Founding a company is not easy peasy.

It takes a lot of time and strategy and money and all that stuff.
ABHISHEK AGRAWAL
For sure.
LIANNE POTTER
Yeah.
ABHISHEK AGRAWAL
So first of all, there were three of us, so I had two co-founders also from Dropbox, and we all worked together at Dropbox.

And really it was kind of a team-first thing where we knew we wanted to work together and build something. And we started exploring different spaces around that same time.

In 2017, one thing that was top of mind for everybody was the 2016 election cycle that had just happened in the US.
CAROLE THERIAULT
Yeah.
ABHISHEK AGRAWAL
And that election cycle in particular, there were some very high-profile email-related attacks.

And being kind of new to the security world, we sort of approached that with, I would say, kind of a very naive, but maybe sort of fresh perspective where we were like, oh, this is kind of strange.

We thought email security was a solved problem. It's this 30, 40-year-old app. You know, why is email security playing a role in elections. This is kind of crazy.

And you start kind of digging at the problem and you realize that there's definitely opportunities to improve upon the current state of things.

So that was the genesis, that specific problem, you know, analyzing the election-related hacks, what could have been done better.

And that really led to some ideas that once we started socializing with our immediate network, we realized that there's an opportunity here.
CAROLE THERIAULT
Ooh, tell us more about that.
ABHISHEK AGRAWAL
So in those election hacks, if you think about what happened, someone was able to breach a mailbox and what that does is gets them, you know, 10, 15 years of email because all of us, when we moved to cloud email, started archiving all this mail.

We have sort of infinite storage. And if you just think about the average mailbox, inbox, it just contains all of this different type of data.

You know, in the personal setting, obviously my entire digital life is housed in my email. In a corporate setting, you know, IP, financial reports, employee and customer data.

Just you name it, it all ends up in email.

And so what we kind of got obsessed with was this idea of, well, yes, it's bad that someone got into an email account, but it's really bad that that means that they can just access 15 years of email, 20 years of email immediately.

And so the first idea was kind of, can we add additional layers of protection?

You know, the buzzword is zero trust or defense in depth, but the idea is that just because I get into your email account shouldn't mean that I literally get to access everything.

There should be additional layers of authentication or defense.

Another thing that that election hack taught us is if I get into your email account, I can go reset passwords to all sorts of other services and actually turn that email breach into now a Dropbox breach or a Twitter breach or a bank account breach.

In the case of the election hacks, you know, people got into an iCloud account where now they get text messages.

So it really opens another kind of interesting point, which is email also acts as identity.

So not only does it have years and years of your digital life in there, it also is your identity for a lot of different applications.

And I can use that to now move laterally from an email account to all these other things.

The key point here is that if I am only trying to stop bad emails from coming in, if that's the only context that I'm thinking about email security in, I'm sort of not really doing anything about the content inside email or the fact that I can use it to move laterally.
CAROLE THERIAULT
So yeah, you're kind of saying that email is the target.
ABHISHEK AGRAWAL
That's exactly right. And that's what we say all the time, that it's not just the way I get in, it's actually the thing I'm after.

And if you think about it only as the way in, then all of your security controls are gonna focus on it as the way in.

But you have to think about it as the actual target of the attacks. For example, very recently, in the US there's been kind of big nation state attacks on government email systems.

Midnight Blizzard was the most recent one. Before that there was SolarWinds, Hafnium, Storm.

In all of these cases, there was not a single malicious email that was sent, but the actual target of the attacks was all of these email content repositories, right?

If I can get into the email account of someone in the State Department, you can only imagine how useful that is from a state actor perspective.

So that sort of illustrates the problem really well, which is if there was no bad email sent, but I can get into an email account in many other ways, like I can bypass MFA, I can install a Chrome extension that gets me access.

I can convince someone to authorize a malicious OAuth application. There's many, many different ways in.
GRAHAM CLULEY
Yeah.
ABHISHEK AGRAWAL
If I get in, what additional controls we can have in place.
CAROLE THERIAULT
I like this a lot. I like the angle. 'Cause I've always thought of email as a vector, but you're absolutely right.

So tell me, how does Material Security, a multi-layered detection response toolkit, what, how does it help? How does, what is, how does it thwart off the bad stuff?
GRAHAM CLULEY
Yeah.
ABHISHEK AGRAWAL
So on the kind of inbound detection side, we're doing honestly a lot of the same things that have been done for a while.

We're just applying new techniques to them, new types of data sources.

So for example, looking for signals that suggest that it is a malicious email, things like it's a sender your organization has never seen before, or it's doing a lot of urgency in its language, even though it's also at the same time trying to request a financial transaction.

And new sort of technology capabilities like AI and sort of a lot of the recent developments with LLMs are massively helpful for this problem because at the end of the day, you're often trying to decipher kind of the intent of these emails in order to understand if they're malicious.

And these language models can be very useful for that, along with just, you know, basic heuristics that you can apply if you can process a lot of data.

On the side of more techniques to actually help in the case that an account is breached and how do you protect the content inside or how do you stop me from moving laterally there, what we take is kind of a defense-in-depth approach.

So a very simple example, let's say that in my mailbox I have a message that's very, very sensitive. Maybe it's got PII or passport information or something like that.

If it is older than a certain age, what Material does is it redacts the contents of that email and it actually leaves a stub that doesn't contain the actual sensitive content.

It's a redacted version of that message.
GRAHAM CLULEY
Cool.
ABHISHEK AGRAWAL
The key thing though is that the user of the mailbox can still get the original contents of the message if they pass a side challenge.

On some factor that is very easy for them to do, but would be very hard for an adversary that had gotten into the account to do.

So for example, in the case of our customers, they're often using an IDP like an Okta or Duo.

And so imagine that I get into a mailbox, I see some messages that have been redacted because they're old and they contain sensitive data.
ABHISHEK AGRAWAL
If I want that message, I press a button, I have to pass a Duo challenge or an Okta challenge.

If I pass it successfully, the message is restored into my mailbox immediately via API. It's seamless. I can interact with the email as I always would in my mailbox.
ABHISHEK AGRAWAL
I'm not going to some third-party website to read my email.
CAROLE THERIAULT
Yeah, yeah.
ABHISHEK AGRAWAL
But then after some amount of time, we're going to redact it again, so that, you know, at rest you're actually protecting this information.

You can apply a similar technique to something like password resets.

So if I go and request a password reset to my Dropbox, well, normally it would just send a password reset email, and if I'm in your account, I just use that to change the password to whatever I want.

And now I've compromised your Dropbox.
LIANNE POTTER
Yeah.
ABHISHEK AGRAWAL
In the case of Material, what we'll do is we'll actually intercept that password reset email and we will first make you prove again on a side challenge that you're actually the one that is requesting the password reset.

If you say yes, we can deliver it as usual. If you say no, then I could be in your account, but I don't get to go change your password to Dropbox.
ABHISHEK AGRAWAL
So you can take these sort of deterministic techniques and just say, hey, there's certain transactions that are so valuable that I'm not gonna let you do them unless you prove your identity again.

And this is really not a new idea. I mean, I'll give you a simple example. Let's say somehow you break into my bank account online.
ABHISHEK AGRAWAL
And it really doesn't matter how, but let's just say you're staring at my bank account. That's bad, obviously.
CAROLE THERIAULT
Yep.
ABHISHEK AGRAWAL
But now let's say that you try to initiate a wire out of it that drains the entire account. What do you think the bank will do? Will it just let you do it? Of course not.
ABHISHEK AGRAWAL
Instead, it makes you verify. It probably will make you reenter your password at a minimum. Probably there'll be some additional verification.
CAROLE THERIAULT
Mm-hmm.
ABHISHEK AGRAWAL
But if you think about email, if I get in once, if I bypass authentication just once, so if I take over a user session, or I bypass MFA somehow, or I get you to authorize a malicious app, that's it.

It's game over. I have access to the entire contents of the email account. I can perform password resets.
ABHISHEK AGRAWAL
There's no additional verification. It just doesn't make sense with all of the things that an email account has and all of the different ways I can exploit it to move laterally.

It doesn't make sense that we treat all messages as equal. Some of them are way, way, way higher consequence than others.
CAROLE THERIAULT
Absolutely.
ABHISHEK AGRAWAL
And our whole idea is that those messages just deserve an additional layer of verification.
CAROLE THERIAULT
Yeah, I really like that because you're right, we kind of treat every email same.

And in fact, the information they contain can make one very unimportant versus one super, super, super sensitive. And it's just sitting in the same bucket.
ABHISHEK AGRAWAL
Exactly.
CAROLE THERIAULT
So do you have any tips for anyone out there listening to this and thinking about next steps to better protect their email and its gateway to the organization?
ABHISHEK AGRAWAL
Yeah, absolutely. So like everything in security, there's always infinite things you can do. There's always another risk you can cover.

And I always advocate for a very pragmatic approach. So the nice thing about email is that there's really only two cloud email systems that most companies are using.

It's either M365 or Google Workspace. So first of all, just making sure you're fully utilizing the native email security controls that already come with the provider is step one.

And you'd be surprised how many companies we talk to where we just see that they're not even properly configuring their existing security controls that they already own thanks to the email security provider.

So doing an audit of those and really making sure, especially in the Microsoft side, things can be intricate and they can be hard to decipher all the different settings.

But that's step one.

I think after that, if you feel the need to supplement the email security that the native provider is doing, maybe you're still seeing a lot of things get through.

That's where an API-based render is something you may want to evaluate. In the past, there used to be a lot of products that would make you deploy inside the email delivery path.

These are called secure email gateways. The modern sort of alternative to those is to actually take an API-based approach so that we're not routing all email through something else.

But post-delivery, you can have something still looking for malicious emails that may have landed in a mailbox.

If after that you feel that you've got those things under control, that's where then I would advocate thinking next about what do I do about some of the content in here?

How can I address some of those gaps? And so to summarize, it's a maturity curve, right?

Start with the basics, make sure you're actually using what the provider gives you by default.

Then think about supplementing with something if you're still seeing things get through.

And then finally, you can address the problem of content and really thinking about extra controls for messages themselves.

But it's a journey and it's better to start with the basics.

Having said that, obviously, my biased perspective is that if you're picking a platform to do some of these things, you don't want 3 different tools to do 3 different aspects of this.

So, it's best to pick one that can be on that journey with you.
