GRAHAM CLULEY
Or you could be one of your colleagues. Right?
MARIA VARMAZIS
Colleagues? You mean my cats? Meow, meow, meow, meow, meow, meow, meow, meow, meow, meow.

Smashing security episode 175 zoom deepfakes Zadoz and Rona Tracing With Carole Theriault and Graham Cluley. Hello, hello, and welcome to Smashing Security episode 175.
My name's Graham Cluley.
CAROLE THERIAULT
And I'm Carole Theriault.
GRAHAM CLULEY
And we're joined this week by a returning guest, a very popular guest. It can only be the one, the only, Maria Varmazis.
CAROLE THERIAULT
The best guest, Maria.
MARIA VARMAZIS
I'm not Gary. I'm sorry that I'm not Gary, but I'm Maria.
CAROLE THERIAULT
Oh no, Gary was great, but you're great. Yeah, it was pretty cool having him on.
GRAHAM CLULEY
And it's also pretty cool receiving voicemails.
MARIA VARMAZIS
Who's it from?
CAROLE THERIAULT
I think you're going to recognize who it is.
GRAHAM CLULEY
I really enjoy Smashing Security. I listen to each new episode every week.
MARIA VARMAZIS
Is it my hubs?
GRAHAM CLULEY
I talk to my wife about this podcast all the time. Sure, she finds this really annoying. I do wish there were more talks about chess and that Maria was on way more often.
MARIA VARMAZIS
Oh, it's my sweetie pie.
MARIA VARMAZIS
There he is.
GRAHAM CLULEY
He likes the podcast so much, he married the guest. There you are. I don't know if that's you or Graham.
MARIA VARMAZIS
After hearing me on Smashing Security. He's a lucky guy. Yes, after.
CAROLE THERIAULT
He's a lucky guy. We all know that.
GRAHAM CLULEY
Before that, you were just a spinster. Nobody wanted you, Maria. But you appear—
MARIA VARMAZIS
You made— You both made my dreams come true.
CAROLE THERIAULT
I don't think you can be a spinster at 24. Oh, I think you can.
MARIA VARMAZIS
You think I'm 24?
CAROLE THERIAULT
Well, before you met Eric.
GRAHAM CLULEY
So, Carole, what's coming up on the show this week?
CAROLE THERIAULT
Well, first, Graham, let's thank this week's sponsors, Boxcryptor and LastPass. Their support helps us give you this show for free.
Now, on today's show, Graham zooms off to find yet another snafu with the video conferencing app everyone's talking about.
Maria is once again knocking on Facebook's door asking WTF, and I chat about the Rona tracing apps that might help us get back up and running.
All this and much more coming up on this episode of Smashing Security.
GRAHAM CLULEY
Now, chums, I almost think we should have a rule.
Just like we have a rule about not discussing the weather on the podcast, I feel maybe we shouldn't keep on talking about Zoom because Zoom's been everywhere, hasn't it?
It's been in the headlines every—
CAROLE THERIAULT
Well, then why are you talking about it now?
GRAHAM CLULEY
Well, because—
MARIA VARMAZIS
It feels kind of unfair to pick on them. You know?
GRAHAM CLULEY
It does a little bit. It's so strange, isn't it, that they are the one which sort of captured the zeitgeist.
Everyone suddenly was installing Zoom rather than Skype, which has been around for donkey's years and does pretty much the same job as far as I can see.
For some reason, Zoom was the one which captured people's imagination.
CAROLE THERIAULT
Well, yeah, because they had 10 million users, and then a month later they had 50 million users.
So it's kind of good that a bunch of security boffins went out and checked out to see how secure or insecure they were. I know why everybody went to Zoom.
MARIA VARMAZIS
That's easy. You don't have to download an app for it. You can just run it out of your browser.
GRAHAM CLULEY
And they'll install it whether you want it or not. That's very true.
MARIA VARMAZIS
So even my aunt, who has absolutely no technical skills, can use Zoom, but she can't download Skype.
GRAHAM CLULEY
Now, it's not just middle managers and middle-aged book club members who are finding themselves tuning into Zoom calls and feeling the pressure of curating their bookshelf and tidying up mess.
By the way, that's one of the most fun things I'm doing when watching TV at the moment.
Is every time someone pops up on a news or a magazine program, I'm not really interested in what they're saying, but we're playing the game of checking out their bookshelf and seeing what books they've got.
MARIA VARMAZIS
You need to get one of those green screens that pops onto the back of your chair. Yeah, those are great.
CAROLE THERIAULT
Doesn't Zoom have some weird background that you can employ to blur it up?
MARIA VARMAZIS
Yes. My background alternates between a huge stack of toilet paper and the Engineering from the Starship Enterprise. I alternate between the two.
CAROLE THERIAULT
What are these? These are apps that you can download to sex it up?
MARIA VARMAZIS
They're just images. Just pick it.
CAROLE THERIAULT
Oh, you just put an image? You can just literally just—yeah, behind you.
MARIA VARMAZIS
I also had Sean Connery in Zardoz as my background. Nobody could look at me with a straight face when you saw him in the red loincloth with all his chest hair. It was great.
I love it.
GRAHAM CLULEY
I hope you were positioned appropriately to—
MARIA VARMAZIS
I absolutely was. Absolutely. So you could just see all of his glory.
GRAHAM CLULEY
Well, it's not just Maria and her ilk who use it. My son, who's only 9 years old, he received a Zoom meeting invitation from his young friends, Rex and Phoebe.
CAROLE THERIAULT
My niece who's 5 gets them.
MARIA VARMAZIS
I'm having a Zoom birthday party for my daughter. Oh. See?
GRAHAM CLULEY
My kid hasn't seen any other kids for weeks. So we thought he'd be chomping at the bit to have some contact with someone less than 5 foot tall.
And it was all set up and it's, okay, yes, let's go into the— Let's go, come on, come on, little Timmy. His name's not Timmy. Come on, Timmy, come on, follow me.
Let's go down to the pleasure palace at the bottom of the garden. Let's sit up on the big screen. And he comes down and everything. Suddenly gets all camera shy.
So basically it's the two mums chatting to each other and the kids.
MARIA VARMAZIS
Bored as always.
GRAHAM CLULEY
He just didn't want to do the video call. And I think truth is many of the rest of us want to get out of video meetings. We're doing anything we can to make them bearable.
Maria, you've got your toilet roll mounting.
MARIA VARMAZIS
Yes, I do.
CAROLE THERIAULT
I think you're being a bit harsh. I am grateful to the back of my teeth that we have video calls and the like to keep me connected with people I like.
GRAHAM CLULEY
Do you like it on video? We never video call each other.
CAROLE THERIAULT
Yeah, I said people I like. People I like. Not people I work with.
GRAHAM CLULEY
So, some people are being very creative to keep themselves engaged. So for instance, Iain Thomson, friend of the show, he was a guest way back when.
MARIA VARMAZIS
Oh yeah, yeah.
GRAHAM CLULEY
He's been doing fancy dress every Zoom call. Different one each day. And on the 38th day, he dressed up as Joe Exotic from Tiger King. So he's there in his leopard print.
CAROLE THERIAULT
I hope he didn't really look like him, 'cause that would be a very sad state of affairs.
GRAHAM CLULEY
Oh no, no, no, no, no. I think he just has a lot of leopard print in his cupboard. But you can understand why people are nervous.
What if you have acne, bad hair, spinach between your teeth? What if you're just fucking ugly?
CAROLE THERIAULT
No one's looking at the other people when they're doing these things. They're just looking at themselves, aren't they?
MARIA VARMAZIS
It's impossible not to. It's like you see a mirror in front of you. I have to disable my video of myself, otherwise I can't really—
GRAHAM CLULEY
I have to as well.
CAROLE THERIAULT
Exactly.
MARIA VARMAZIS
It's too distracting.
GRAHAM CLULEY
I just look into those beautiful eyes, those deep pools of desire, and I just think, look at that hot hunk of love there. And so I have to turn it off. I have to disable the webcam.
GRAHAM CLULEY
Sorry, Crow, you alright?
CAROLE THERIAULT
Yeah, I'm fine.
GRAHAM CLULEY
Well, look, help is at hand if you're one of those people who don't want to be on the video call, because there is now an open source piece of software called Avatarify.
Avatarify, I don't know.
MARIA VARMAZIS
They did not work with marketing. Avatarify.
GRAHAM CLULEY
Avatarify. Avatarify. I keep on saying Avafartify.
MARIA VARMAZIS
I'm avatarified of that name.
GRAHAM CLULEY
You're terrified of it. What it does is it takes the input from your webcam and then deepfakes someone else's face onto yours.
So, it doesn't care what video conferencing app you're using.
MARIA VARMAZIS
So I really can be Sean Connery from Zardoz?
GRAHAM CLULEY
You could be!
MARIA VARMAZIS
I need to do this! I'm getting on that.
GRAHAM CLULEY
Or you could be one of your colleagues. Right?
MARIA VARMAZIS
Colleagues. You mean my cats? Meow, meow, meow, meow, meow, meow, meow, meow, meow, meow. I could be pickles or chili. Which one?
GRAHAM CLULEY
It doesn't care if you're using Skype or Zoom because it's just looking at the webcam thing and just meddling with it before it goes to the app. Right.
Now, in the old days, June last year, Jessica Barker in episode 134, she told us how scammers in France had made a stage set, had created a silicone mask, they dimmed the lights, and pretended to be the French Defence Minister.
GRAHAM CLULEY
And they conned €80 million out of people via a dodgy video call. Nowadays, they could do all of that with software. So you don't need an amateur dramatics group to help you out.
Now, avatarify—
CAROLE THERIAULT
Avatarify. It's not hard.
GRAHAM CLULEY
It is hard.
CAROLE THERIAULT
Avatarify. Avatarify.
MARIA VARMAZIS
It's avatarify.
GRAHAM CLULEY
It's a bit like cesia. It's one of those words which is very tricky to say. Avatarify. Yes.
So Avatarify was released by a programmer called Aliyev on GitHub, based upon existing deepfake projects.
So he didn't recreate it from scratch, but it works in real time, replacing your faces. It only took him a couple of hours to whisk it up.
CAROLE THERIAULT
I'm sure he did great security testing.
GRAHAM CLULEY
Well, before you know it, he was testing it on his colleagues on their regular Monday morning Zoom call.
And he's actually produced a video which you can check out, which purports to be a Zoom call between two of his colleagues when an unexpected visitor arrives.
Unknown
Wait a second. Somebody's trying to connect to our conference. Okay, who is it? I don't know, one second. Hey guys! Are you Elon Musk?
Yes, looks like I got into the wrong conference in Zoom. How are you doing, guys? Good, how are you? I'm nice, thank you.
MARIA VARMAZIS
Yeah, I'm sorry. No, that looks weird. That's not gonna convince anybody.
GRAHAM CLULEY
Right. It's not entirely convincing, but then—
MARIA VARMAZIS
The dead eyes. Oh my god. Dead fish eyes going on, and the mouth going—
GRAHAM CLULEY
Well, maybe that is convincing Elon Musk, right? I mean, you know, he's not entirely convincing.
CAROLE THERIAULT
Oh, is that what you're trying to suggest, that he's not as good-looking and fetching as you, Graham?
GRAHAM CLULEY
I'm just saying he's a little bit alien anyway. So maybe people would fall for it.
And if you have a rubbish internet connection, you're used to seeing low-quality video and artifacting.
Or if you're in a meeting with 10 other people all streaming their webcam, your picture's quite small and blurry anyway. Now, it's not perfect, as you can see.
It is pretty easy to work out the moment, and it doesn't do voices, but surely that is only a matter of time, and some of these issues will get fixed.
CAROLE THERIAULT
Are you seriously suggesting that this is how people deal with their shyness on video content?
CAROLE THERIAULT
Is that what this is about?
GRAHAM CLULEY
No, I'm just suggesting this is a scary new way in which deepfake technology is going.
If you think about how far we've come in the last two years, and now this is happening in real time. We know already some people are capable of deepfaking audio.
This doesn't do voices, but—
CAROLE THERIAULT
So you're thinking that in a year or two, someone's gonna call me up purporting to be you, have your mug on his or her face, and go, hey, hey, hey, Carole, podcast stuff, blah, blah, blah, blah, and I'm gonna fall for it.
MARIA VARMAZIS
Or somebody could Zoom bomb one of the current Zoom meetings. I mean, do you really know what people sound like, though? I mean, voices, does it even matter?
Unless the person has a distinctive voice and you're really familiar with them. If you just fake it, if it's a male voice and you're a man, most people would probably go, okay.
GRAHAM CLULEY
Or maybe you pretend you got a cold. You're talking about that all the time, right?
MARIA VARMAZIS
Yeah, I think if somebody Zoom bombed a meeting, I don't know why you would do this and why this would convince somebody, but if you tried it, it might actually be crazy enough to work.
Not that I'm going to do it as Sean Connery, but I mean, I don't know why you mentioned that.
GRAHAM CLULEY
I reckon it's only a matter of time, Maria, until you're donning his mankini, his space-age mankini. You've got the fake chest wig on.
MARIA VARMAZIS
Have you not seen Zardoz?
GRAHAM CLULEY
Carole, do you not know this movie?
CAROLE THERIAULT
You've not been drinking enough. Are you hydrated?
MARIA VARMAZIS
Have you not seen Zardoz, Carole?
MARIA VARMAZIS
No, I'm sorry. Oh, well, okay. Well, a giant floating head with guns coming out of its mouth just how the movie starts. So, you know, I'm running to it now. You need to see it.
You need to see it. That's my pick of the week, by the way.
GRAHAM CLULEY
Maria, what's your story for us this week?
MARIA VARMAZIS
Can we just talk about Zardoz some more? Would that be all right?
GRAHAM CLULEY
I think we should do maybe a commentary on it.
CAROLE THERIAULT
I don't think that would be good for our Patreon supporters. Come on.
GRAHAM CLULEY
What have you got for us, Maria?
MARIA VARMAZIS
Facebook is doing a thing. Actually, you know, Facebook's not— I mean, it kind of is. All right, so here's my story.
So in the special kind of stupid that only America can provide, there are people in this great land protesting coronavirus quarantine measures in large groups.
CAROLE THERIAULT
Which of the states are the worst for this?
MARIA VARMAZIS
I don't know about worst, but it's basically every state has had one of these protests. Even my state of Massachusetts, we had one.
GRAHAM CLULEY
Even Massachusetts?
MARIA VARMAZIS
Yeah, tiny, tiny little—
CAROLE THERIAULT
Practically British.
MARIA VARMAZIS
Yes, we're New England, dammit. We've had, I think every state has had one at this point. Sure feels like it. And they're very small gatherings.
Like, my wedding was bigger than most of these gatherings.
CAROLE THERIAULT
But you are Greek.
MARIA VARMAZIS
No, no, I had a small wedding actually. Okay, point of correction.
But I mean, these gatherings are not terribly big, but they are happening, and people are not social distancing at these, and they're certainly not wearing any kind of protection most of the time.
Sometimes you see people with masks on anyway. It's really weird.
GRAHAM CLULEY
It is weird when you see them having a banner and they've got a mask on.
MARIA VARMAZIS
Yeah, the cognitive dissonance is, I mean, I've been living here for my whole life and even I'm just stunned by it. I just didn't think it was possible.
CAROLE THERIAULT
So are these protests saying we want to go back to work and we don't want to wait for the go-ahead? This is unfair. It's against our amendment, right?
MARIA VARMAZIS
Yeah.
These are protests that are sort of directed usually at the governor of everyone's respective state saying these measures are too draconian and we need to just go back to normal and let people die who are going to die and cull the herd kind of thing.
Absolutely. I mean, I wish I was exaggerating, but people actually have signs saying things like, "Let the weak die." I mean, it's just, I just—
GRAHAM CLULEY
It's one of your constitutional rights, I imagine, isn't it? To choose the moment of your death, perhaps, and the method.
MARIA VARMAZIS
Well, I mean, so the reason I'm even talking about this story on this podcast is there is actually a Facebook tie-in.
So Facebook has announced, as part of their whole trying to actually help and squash misinformation about COVID-19, that they're actually trying to quash these events because I think people are organizing them in large part through Facebook events.
So they're waiting for the states to tell them, hey, there's a protest being planned, you should put a stop to this, Facebook.
It sounds like they're not actually going out and seeing them and taking them down themselves unless the state is telling them to.
GRAHAM CLULEY
Oh, so Facebook is saying if we're asked by the authorities, then we will take these Facebook events down.
CAROLE THERIAULT
I think it's maybe more complicated than that.
GRAHAM CLULEY
How does this work?
CAROLE THERIAULT
So you have— you've got Donald Trump who keeps flirting with let's open up the states. Sorry, the states.
MARIA VARMAZIS
Yeah, the states. Just business. Yeah.
CAROLE THERIAULT
But it's the governors that make that decision, that make that call.
CAROLE THERIAULT
So Trump's saying open them up, please. And you've got the governors going no way, Jose.
And some are saying, oh, okay, if you say so, then that's great for me because we have no money. You know, we need to get people back to work.
MARIA VARMAZIS
So, yeah, I mean, people are certainly hurting.
I mean, even where I'm at, a lot of my neighbors are really, really hurting and nobody's been getting the money from the government that we were told we would be getting.
So I get the why in some cases why people are hurting.
The sort of weird catch-22 of Facebook waiting for a state to tell them, the reason this is sort of a flag to me is that that can flirt kind of dangerously with a governor saying you can't protest, which is basically a First Amendment violation.
So there's a great quote here from Ohio Governor Mike DeWine that says, the governor values the First Amendment and asks that protesters practice social distancing by standing at least 6 feet apart.
CAROLE THERIAULT
So you're saying governors can't actually ask this because it's a First Amendment problem?
MARIA VARMAZIS
I don't know if they can't or they might and then just wait and see what happens later. It might be one of those, like, we'll deal with the ACLU later.
Right now we need to keep people alive. Certainly some state authorities have asked Facebook to do this.
I don't know if it's literally the governor, but I imagine if states come in and say, we need to put an end to this, Facebook, stop it, people are gonna say, actually, it's my right to protest and get other people sick.
This country, I swear to God.
So, but Zuck was saying that his company is working to remove posts that violate basically the best practices, and they are also going to try to put a stop to anything that violates social distancing measures.
So I can imagine someone would be, I'm creating an event, but it's required that all attendees stand at least 6 feet apart. That might be enough to get around this. Who knows?
It's such weird times.
CAROLE THERIAULT
Okay, but you know, so is that— I think it is, but you know, on Thursdays in the UK, in the evenings, we have a little clap-a-thon from our gardens for first responders.
CAROLE THERIAULT
And I don't know if you saw on Friday last week, there was a huge hoo-ha because the Met Police organized a clap-a-thon on Westminster Bridge. Loads of people showed up.
They're all hanging out on the bridge. Some people holding babies. Nobody's masked. Everyone's just hanging around clapping.
Ironically for the health first responders who were actually going to probably save some of the people's lives.
MARIA VARMAZIS
They're all going, "Go home!"
GRAHAM CLULEY
"Go home!" And I saw first responders responding to it on Twitter.
CAROLE THERIAULT
Yes, don't blame them.
GRAHAM CLULEY
And saying, "What the bloody hell do you think you're doing?" Yes!
CAROLE THERIAULT
It was just incredible, and it was just such a huge— It was embarrassing to see, and I'm sure those involved were just, "Oh my God." I mean, that is certainly a bad idea, what they're doing.
MARIA VARMAZIS
It's sort of misplaced kindness. Road to hell. Yeah, yeah.
The protests though that are happening around the states, as many of us have been reading about, there is some credible evidence that they have been astroturfed.
They have been not exactly a groundswell of grassroots support, that maybe some folks with malicious intent have been planting the seeds on this discussion to try and manipulate people into this kind of action.
CAROLE THERIAULT
I would not be surprised at all, especially after all the things that were unveiled after the 2016 election.
GRAHAM CLULEY
Oh, whoa, whoa, whoa. I'd be very surprised if someone was meddling in such a fashion. There's no track record of anything like that, is there?
MARIA VARMAZIS
Are you individual number one? Is that what you're saying? Yeah, it's interesting, scary, sad. Thankfully, these folks that are doing this kind of protesting are the tiniest minority.
The vast majority of people here regardless of their political affiliation have good sense.
CAROLE THERIAULT
Hey, but you still have cell phone masks, so there's that.
GRAHAM CLULEY
Oh, please.
MARIA VARMAZIS
Again, I understand the economic pressures that people are under. I'm around it all the time. I'm out of work. I get it. It's just, I mean, you can't shoot a virus, America.
It just doesn't work that way.
And there certainly is a contrarian streak in this country of folks seeing everybody doing one thing for the common good, and there's always going to be other folks that go, well, F that.
CAROLE THERIAULT
Do you not think it's just an effort in gaslighting? Do you think the people that are there are really saying, we want all the lockdown lifted and it's okay?
MARIA VARMAZIS
Well, listen, I mean, tomorrow in Massachusetts, Governor Baker could say, hey, lockdown's lifted, go about your business. Everybody's still gonna stay home around here.
Nobody wants this. I mean, the governor could say whatever, but that doesn't change what's actually happening in the hospital.
So, you know, I'm not waiting for the governor to give me the okay. Let me put it that way.
GRAHAM CLULEY
So would you like it if Facebook and other social media sites were being more proactive about doing something about this, or do you think that's the wrong approach as well?
MARIA VARMAZIS
Yeah, that's what I've been chewing on a lot, because I do understand the First Amendment issue that could come up with this.
That said, I mean, this actively puts people in harm's way.
I mean, even if these folks just infect each other, there are more bodies in the hospital, could get more health workers sick and get out and, you know, infect innocent people.
To me, it's— oh my God, I can't believe I'm about to say this— it's a hair away frankly. So, oh boy, I'm gonna get reamed for that.
GRAHAM CLULEY
Well, on that cheery note—
MARIA VARMAZIS
What, the reaming? No, no, just— oh man, nobody's gonna like that I said that, but I think these people are crazy dangerous.
CAROLE THERIAULT
You know what, we're gonna censor it. No one's gonna know what you actually—
MARIA VARMAZIS
Okay, okay, thank you.
CAROLE THERIAULT
Just that word's gonna be bleeped.
MARIA VARMAZIS
All right, whatever, I'm already out of work. Nobody can get me less out of work now, so it's fine. Whatever, my reputation's already in the shitter. It's because I come on this show.
GRAHAM CLULEY
Carole, what's your story for us this week?
CAROLE THERIAULT
Okay, well, you know, it ties in well with Maria's topic, right?
MARIA VARMAZIS
So, is it about coronavirus?
CAROLE THERIAULT
Well, what isn't these days, right? So people need to get back at work. The economy needs people back to work. Companies want their staff back.
People want to go back to work so they can keep a roof over their heads and food in their bellies. And the question is, how do we do this safely?
We don't want companies to become big breeding grounds for the virus.
CAROLE THERIAULT
And we don't want to overwhelm hospital capacity like we talked about. So we need something that protects the economy, first responders, and everybody else.
Yet countries are right now relaxing lockdown rules. We're seeing it happen in places like you said in the States, but also in Europe.
Germany is just starting to do it as well with small shops.
But there seems to be a general consensus amongst the scientists that tracking infections is the key to controlling the spread.
So in other words, if you can trace, contact trace, how would I put this?
GRAHAM CLULEY
I think that's it. So if you can identify who's been infected and who they've come into contact with, gives you a heads up as to who else might be spreading it, right?
CAROLE THERIAULT
It would help contain future flare-ups, right?
So there's all these guys out there, these countries and even businesses that are trying to find a way that we can actually contact trace people.
There's pluses to it because you could automate the assessment of who's at risk and telling them to go see a doctor or to get tested or to self-isolate.
There's an international scramble to get all these track and trace systems up and running. And there's— I read somewhere, in a plague, civil liberties are suspended.
The trick here is to balance the limiting of the spread of the disease without us waking up in an Orwellian surveillance state.
Because there's careful balancing here, because once we put something in place, it isn't gonna be easy to get rid of.
WILLIAM GREEN
Even if that isn't the intention. The problem is perception, isn't it?
Because you need the public to be on board with whatever you're going to do, your way of using technology to track and trace people.
And so they need to be reassured that there's no chance that something dodgy might happen in the future.
CAROLE THERIAULT
I don't know. I think it's more than that, but there's lots of different approaches. So I almost didn't do this story because it's just too crazy, right?
Every single country is applying this slightly differently.
CAROLE THERIAULT
So I'd love to be able to say this is what they're doing, but I kind of have two camps here. One camp is the centralized network-based location tracing.
The reason people use this approach is it means you eliminate the need for apps, right? They need the phone, but they don't need to download an app.
So you get rid of people voluntarily downloading or basically choosing not to.
These network-based solutions basically have access to raw location data and they can alert you if you've been near somebody. Significant privacy problems, many say.
CAROLE THERIAULT
South Korea, instead of using a dedicated app, used a system gathering tracking information from a variety of sources, including your mobile device tracking data, card transaction data, and combined all these to generate notices or SMS messages to potentially infected individuals.
And in addition to using this information to alert potential contacts, the government also made this location information publicly available. So basically saying, oh, right.
And this is something that wouldn't be permitted here in the UK. Thank you, privacy laws. But this happened because of the MERS outbreak.
And so back then they changed some of the privacy laws.
GRAHAM CLULEY
Being too nerdy, and I know it's your favorite topic, but wouldn't GDPR have an impact there?
Because even if it's happening in South Korea, if you were a European who was visiting South Korea and your personal information and you were being tracked, wouldn't that potentially be?
CAROLE THERIAULT
Yeah, but no one's traveling right now, dude.
GRAHAM CLULEY
Okay, yes, true, true. Okay, ah, damn, damn, you ruined it.
MARIA VARMAZIS
Sorry, gotcha.
CAROLE THERIAULT
Oh, shit. Zing zang. Okay, so that's the centralized network-based location tracing, right? Now the other approach, the other camp is privacy-preserving contact tracing.
Personally, I find that name a little rich. I would say privacy-friendlier solution. OK. And this uses Bluetooth, right? BLE.
So it basically uses that to log a user's proximity to other mobiles.
And then users can receive a message they've been in close contact with someone who tested positive for COVID-19.
MARIA VARMAZIS
Interesting. OK.
GRAHAM CLULEY
So that wouldn't track your specific location, but it'd be basically pinging to see what other devices are in your vicinity.
And over time, if one device is known to belong to someone who has the disease, they can say, oh, but they also came into close contact with these people as well, or these devices too.
That's right.
CAROLE THERIAULT
But you can imagine, think about it in actual practice, right? So imagine we all, along with, I don't know, 30 other people— how many?
I don't know how big the supermarket is, but we're all in a supermarket, right? And there's one guy there who's infected.
CAROLE THERIAULT
And everyone's phone goes off but his, right? Saying, ding, ding, ding, potential infection! And everyone runs out of the store.
GRAHAM CLULEY
I don't think it works in real time quite like that. I don't think it's Scarlet Letter, I don't think it's diagnosing someone and saying, whoop, whoop, whoop.
It's not a radar or a Geiger counter telling you someone's close to the grenade.
MARIA VARMAZIS
No, maybe it's just play an obnoxious ringtone like it's the early 2000s again, like Crazy Frog, and everyone's gonna go, "Ah, fuck," and then just— Oh yeah, and that'll get everybody running.
CAROLE THERIAULT
So Apple and Google say they're working together on interoperability for their Bluetooth, so that people with Android iOS devices— It would be nice. Yeah, wouldn't it be nice?
It took this, guys.
MARIA VARMAZIS
Heal the world. World healing.
CAROLE THERIAULT
Took a pandemic to finally get you guys to play nice together.
GRAHAM CLULEY
But it would have to be turned on all the time.
CAROLE THERIAULT
It would have to be turned on all the time. And there's a number of— you know, this isn't a perfect solution either.
I mean, does this mean that people have to carry their phones around with them all the time?
MARIA VARMAZIS
Yeah, 'cause a lot of people don't. And a lot of people don't keep Bluetooth on. I certainly don't. I know my husband doesn't.
GRAHAM CLULEY
What's gonna happen to your battery life?
MARIA VARMAZIS
Also privacy issues. My husband never has his on. He just always has it turned off.
CAROLE THERIAULT
And Graham, when I was talking to him about this story earlier, he said, "Well, what if someone just duct taped the phone to a cat and let it run around?"
MARIA VARMAZIS
You know, an infected flare.
GRAHAM CLULEY
Around the neighborhood.
CAROLE THERIAULT
See, I give you credit. I didn't steal it clean.
MARIA VARMAZIS
Hey, cats can get coronavirus, but dogs can't.
CAROLE THERIAULT
Oh, that's true. That's true.
GRAHAM CLULEY
Or what if you're in a tower block and the people on the floor below have got it. You never come into contact with them, maybe other than perhaps in the elevator.
Your phone's constantly pinging, "You're still there!" Exactly, but some data's being collected that you were in the vicinity.
It's a very difficult thing to do reliably, and I think if it's prone to making lots of mistakes—
CAROLE THERIAULT
Well, I don't know, I don't think anyone knows whether it's prone to make a lot of mistakes yet, and also you have to remember we're in a— We're in a fricking pandemic, clearly, so something has to be done.
So we can sit there and poke holes in all the suggestions, but take this. This is one of the biggest problems with this.
Modeling by researchers at Oxford University suggested that 80% of all smartphone users in a city of 1 million people would have to use the tracking system to halt the virus spread.
So 80% of people in a 1 million people city have to be using it, otherwise it won't work.
GRAHAM CLULEY
Oh no, you're poking holes in it.
CAROLE THERIAULT
Okay, so that means you've got to get a lot of people to use it.
CAROLE THERIAULT
And Germany are saying, "Hey, we really like this idea, but we want this to be voluntary." Colombia did something like what I expect maybe the UK or the United States to try and do to get people on board is to give them a little treat, an incentive.
MARIA VARMAZIS
As a treat.
CAROLE THERIAULT
So the Corona app in Colombia is a government mobile app, and it's been downloaded by 1.2 million users.
So it's still quite small in terms of population, but it's a free application which doesn't consume any data.
And the idea is it helps detect affected areas and nearby people with a positive diagnosis. Graham, listen, listen up.
GRAHAM CLULEY
No, I'm listening, I'm listening.
CAROLE THERIAULT
Corona app facilitates the real-time monitoring of data collected to the emergency operations center in the Instituto Nacional de Salud. Ooh la la! Real-time monitoring.
And as an added benefit of the app, the government will finance 1 gig per month and 100 minutes for users of prepaid lines that install it.
GRAHAM CLULEY
But real-time doesn't necessarily help you, does it? Because—
CAROLE THERIAULT
Well, I don't know. If you're walking down Waitrose or wherever you—
GRAHAM CLULEY
No, no, no. If you've got the damn thing, Carole, if you've got the symptoms, you're not meant to be down the supermarket, are you?
You're meant to be in bed or you're meant to be in hospital.
CAROLE THERIAULT
Well, I suspect they might use this app to tell you as well that your results have come in.
CAROLE THERIAULT
Open the envelope, ding, ding, ding.
GRAHAM CLULEY
All I'm thinking is that people are spreading the disease while they haven't actually got the symptoms, right, for a couple of weeks.
CAROLE THERIAULT
Absolutely.
GRAHAM CLULEY
But I think there's a bigger problem with this, right? You're talking about this being compulsory.
What about all the 70-year-olds and 80-year-olds, the ones we're meant to be trying to protect right now?
MARIA VARMAZIS
Yeah, they don't have cell phones, yeah.
GRAHAM CLULEY
Or they certainly don't have a nice smartphone. They'll have an iPhone 3GS if you're lucky. And God knows that's not gonna get the operating system update from Apple, is it?
It's not gonna be able to run the app.
CAROLE THERIAULT
Yep, good point.
GRAHAM CLULEY
So are they going to supply us all with a brand new phone? That'd be rather nice.
MARIA VARMAZIS
They're probably gonna have to supplement this with good old-fashioned, a person actually doing contact tracing. That's what they're doing in my state at least.
They've got the National Guard making phone calls to people, doing it manually, and it's not working very well 'cause nobody's answering the phone. They think it's spam.
But that's what's happening right now is that we're trying to get to where South Korea was. We're trying to model them a lot.
And so we have a lot of people actually doing a manual contact trace.
CAROLE THERIAULT
I don't know if they had people running around the streets saying, hey, let us out.
Okay, so Amnesty International and over 100 other organizations just issued a statement calling for limits on this kind of surveillance, right?
They're really worried about what some organizations or government organizations might include or allow in the app, the flexibility they might allow to add future surveilling components to it.
GRAHAM CLULEY
Or a nasty government, not like the British government, for instance, one of those other countries, right, Maria?
MARIA VARMAZIS
What? Yeah.
CAROLE THERIAULT
So they're saying there's 8 stipulations, but a few of the important ones is it has to be lawful, necessary, and proportionate, the surveillance.
And extensions of monitoring and surveillance would have to have a sunset clause, which means when the alarm goes down, this stuff goes away.
You can't just remain enforced indefinitely.
MARIA VARMAZIS
Yeah, I mean, there's certainly an instinct from a lot of people to be privacy just should go immediately out the window, it doesn't matter, everybody.
And I'm happy to hear about that sunset clause. At least gives me some comfort.
GRAHAM CLULEY
But you know what, Maria, if you've got all those crazy people right now protesting, how are they going to feel about having to carry their phone and the app being installed.
That's going to really rile them up.
MARIA VARMAZIS
Yeah, yeah, it is. I mean, a lot of those folks, I know there's the Venn diagram has a large overlap with anti-vaxxer, anti-5G stuff.
GRAHAM CLULEY
Uh, yeah, Auntie Margaret. Just my Auntie Margaret.
CAROLE THERIAULT
I think, you know what, I think they're extremely small part of the population.
I think they make a lot of noise because it's sensational and our media are too focused on trying to get clicks.
MARIA VARMAZIS
I have a feeling it's gonna have to be, there's a certain percentage of the population will need to have some sort of interfacing with this.
And if, I don't know, the epidemiologists will know the answer, but say it's just 80%.
If we have 80% of the people doing or interfacing with the system in some way, that's enough to give us a sense of herd immunity.
That doesn't make sense, but I'm sure 100% is just not, doesn't seem possible.
CAROLE THERIAULT
They do talk about digital herd immunity.
MARIA VARMAZIS
Interesting. Yeah, there's no way we can get 100% of everybody for all sorts of reasons.
CAROLE THERIAULT
Look, I get it, right? The least physically invasive solution is using technology we already have, and particularly one we keep on our person virtually at all times.
Using mobiles to track and trace infections makes sense, but it's vital that governments and tech firms operate with morality, transparency, and respect for our current civil liberties.
If their security is not baked into these apps from the very start, we risk a massive shit show on our hands. 1984 is a great read, but none of us want our future to be like it.
See, cheery, right?
GRAHAM CLULEY
Well, excellent. So, Carole, thank you very much. I think I'm just gonna hibernate until 2525 and put my head in the sand.
MARIA VARMAZIS
You know you are going to wake up in Zardoz's world if you sleep that long. Who is Zardoz? I really need to see this.
CAROLE THERIAULT
He is Zardoz.
MARIA VARMAZIS
Okay, just Google Zardoz for me right now. Z-A-R-D-O-Z. Just duck, duck, go it. Use your search engine of choice. Z-A-R-D-O-Z.
CAROLE THERIAULT
I'm just afraid.
MARIA VARMAZIS
Don't be afraid.
GRAHAM CLULEY
It's nothing you haven't seen before.
CAROLE THERIAULT
Ooh, sexy. You haven't met my husband, have you?
MARIA VARMAZIS
I don't know how to answer any of these questions. I'm pretty sure I have. But also, what?
CAROLE THERIAULT
I don't know. I kind of like it. Hey, Graham?
CAROLE THERIAULT
So I've got a problem.
CAROLE THERIAULT
I use a cloud service. I put all my files and data up there, and I'm kind of nervous about prying eyes looking at it. Any advice?
GRAHAM CLULEY
Yeah, you've got to encrypt it. So what I would recommend is use a piece of software like Boxcryptor. It's what I run on my computer.
And any file before it gets uploaded to those cloud services gets encrypted with my own keys, which I control.
So the cloud service itself can't see the contents of the files, which I'm putting on the cloud drive. It's all encrypted.
CAROLE THERIAULT
Cool. I'll check it out.
GRAHAM CLULEY
Well, now's a great time to do it because they're offering a fantastic 40% discount to listeners of the Smashing Security podcast.

MARIA VARMAZIS
On with the show.
GRAHAM CLULEY
And welcome back, and you join us on our favorite part of the show, the part of the show that we like to call Pick of the Week.
CAROLE THERIAULT
Pick of the Week, Zardoz—
MARIA VARMAZIS
I mean, 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 Zardoz-related necessarily.
CAROLE THERIAULT
It can't be unless it's Maria's choice.
MARIA VARMAZIS
It's not my Pick of the Week.
GRAHAM CLULEY
Well, my Pick of the Week this week is a website called Sketchplanations.
GRAHAM CLULEY
And Sketchplanations is a cute little website run by a chap called Jono Hay.
And once per week, he grabs his iPad Pro and his Apple Pencil, and he draws a sketch explaining something. And I think it has a certain charm.
And he also writes a few paragraphs explaining the thing which he is explaining in the sketch and giving you some more details. We can read more about it.
And it can be about all manner of subjects, everything from business to Chindogu. Are you familiar with Chindogu? I don't know if it's Japanese or Chinese.
It is the art of unuseless inventions. And so he gives the example.
CAROLE THERIAULT
Unuseless? So useful.
MARIA VARMAZIS
Yes. I'm pretty sure that's Japanese.
GRAHAM CLULEY
He gives the example of the back scratch shirt, which is a t-shirt which has coordinates on the back of it, rather like a game of battleships, which can help someone work out where you want to be scratched.
CAROLE THERIAULT
Okay, I like that idea a lot. Except the image you have here is totally outside. It doesn't even cover the areas that I like.
GRAHAM CLULEY
Oh, it's just an example—
MARIA VARMAZIS
Well, you need to make your own. Clearly you need to tattoo coordinates on your back.
CAROLE THERIAULT
Yes. Yes.
MARIA VARMAZIS
Just tattoo it.
GRAHAM CLULEY
But all manner of other things as well. And he has very cute little drawings.
And Carole, when I saw these cute little drawings, when I first visited Sketchplanations, I thought of you, not because you're cute and little. That would be ridiculous.
But because the drawings you do are a little bit in this style. I know you're quite artistic. So I quite like it. Check out Sketchplanations.
CAROLE THERIAULT
You know, I'm gonna try not to be— Yeah, okay. Thanks very much, Graham. That's very sweet. These are stick men.
MARIA VARMAZIS
Everybody?
CAROLE THERIAULT
Stick men. That's all I gotta say.
MARIA VARMAZIS
Oh, the Peter Principle. That's my favourite one.
MARIA VARMAZIS
Is that why I never got promoted? I was just too smart. No, that's not why.
GRAHAM CLULEY
Why is that called the Peter Principle, by the way? Does anyone know?
MARIA VARMAZIS
Is it a Dilbert thing, I think?
GRAHAM CLULEY
Oh, I don't know.
GRAHAM CLULEY
I wonder if Peter was another word for— A bit like the cock principle. I just wanted to—
MARIA VARMAZIS
What do you mean?
GRAHAM CLULEY
Anyway, Sketchplanations is my pick of the week.
GRAHAM CLULEY
Maria, what have you got for us this week?
MARIA VARMAZIS
You're gonna be surprised. It's not about the movie we've been discussing. It's about coronavirus. Yay!
GRAHAM CLULEY
That's your pick of the week? You're recommending?
MARIA VARMAZIS
Yes, my pick of the week is coronavirus.
CAROLE THERIAULT
I think we need to add that into our pick of the week no-nos, Graham.
MARIA VARMAZIS
What? Coronavirus?
CAROLE THERIAULT
No Rona refs.
MARIA VARMAZIS
No Rona refs? I see. I was wondering if you were gonna come down hard on me on that one.
We won't this time because we didn't say anything, but from now on I had a feeling though you might be like, no more, but these are actually uplifting. I'm just saying.
GRAHAM CLULEY
Let's hear it.
MARIA VARMAZIS
So, okay, so I mean, to me they're uplifting.
So I mean, I think it's pathetic that there's no PPE for a lot of people right now, and folks like me who know how to use a sewing machine are making masks for friends and family.
It's pathetic, but it makes me feel like I'm doing something slightly helpful while just sitting on my ass.
So I love how much the maker community has really rallied to figure out how to homebrew a lot of stuff that people need.
And when I say maker, I like the phrase maker is basically like men who figured out you can make things.
MARIA VARMAZIS
It's like women have been doing this forever, but whatever. So in this, again, another phrase I'm just going to get yelled at for.
In this case, I'm including in makers like more quote traditional domestic types, like people who sew, as well as people who use a 3D printer.
And Makezine, which is a really cool magazine of all sorts of recipes for making stuff, has some really awesome resources for make these projects to fight COVID-19 right now.
So whether you know how to use a sewing machine or even just want to cut up a t-shirt to make your own mask, or if you have access to a 3D cutter or 3D printer, there's a whole list of free resources and free recipes and stuff you can make.
CAROLE THERIAULT
It's very cool.
MARIA VARMAZIS
It's super cool. And if you're handy with your hands in any way, if you know how to make stuff, there's probably something on that list for you.
My absolute favorite one is 3D printing a bias tape maker, which is basically if you've got a 3D printer, you can help out people like me who know how to sew.
You can buy them at stores, but they're all sold out now.
MARIA VARMAZIS
So it's just a tiny little doohickey that a 3D printer can really easily make, and it's very, very helpful for people who know how to sew and drastically speeds up their process.
CAROLE THERIAULT
It really does, actually, because it's super great.
MARIA VARMAZIS
Yeah. So especially now that also elastic is sold out everywhere, bias tape duct tape is the next best thing for affixing a mask to your head. It just makes a very strong tie.
And sort of a secondary pick of the week is this website called Fix the Mask.
It's a very interesting makeshift solution to making a surgical mask slightly more tight-fitting on the face and provide a better seal using just rubber bands.
MARIA VARMAZIS
I thought it was, I don't know if it's actually as good as the site purports it to be, but I thought it was a very fascinating potential fix.
CAROLE THERIAULT
I have also a very good mask design, which I'll add to the— your links, if I may.
MARIA VARMAZIS
Absolutely. I mean, my personal favorite, the one that I've been making, is called the Foo Mask, and it's on freesewing.org.
I've made a ton of these for friends and family, but it's hard to breathe through by design.
You're supposed to put a heavy fabric layer in it, so it's not going to be comfortable in warmer weather.
GRAHAM CLULEY
So, and I've just shared with you both a link to a tweet with a video of a chap.
I think he's Italian or something like that, demonstrating how you can make a face mask out of a t-shirt, just the way you fold it and wrap it around your head.
MARIA VARMAZIS
Oh yeah, absolutely. There's so many interesting solutions.
GRAHAM CLULEY
It's quite clever, quite imaginative, the way some of these things work. Well, there you go. What an uplifting and wonderful Pick of the Week, Maria.
MARIA VARMAZIS
Oh, thank you.
GRAHAM CLULEY
And also Zardoz. We'll try to prevent you from mentioning it.
MARIA VARMAZIS
Next time I won't. Next time my pick will be Zardoz. Just Zardoz.
GRAHAM CLULEY
Us. Crow, what's your pick of the week?
CAROLE THERIAULT
So many of us are starting to watch our pennies if we hadn't already started, and some of us are getting rid of services that might feel slightly more indulgent now that we might be more worried about bills or feeding the fam.
If you're one of those people, or you know someone who is, you might be happy to hear that Netflix has made 30 of its educational productions available for free on YouTube.
MARIA VARMAZIS
First one's always free.
CAROLE THERIAULT
Yeah, so you've got 30. Now what's cool about these is they're all family friendly. They're a lot of Attenborough videos. The Planet videos are part of that list.
There's this documentary that Netflix did on babies which I haven't seen, but I've heard everyone talk about it, but I haven't seen it myself yet. So it's a good mix.
There's probably about 1,000 hours of viewing pleasure there where you'll actually learn some stuff. Am I making that up? Oh, that's probably impossible.
MARIA VARMAZIS
I don't know about that, but no, 30 shows, that's literally impossible.
CAROLE THERIAULT
It's probably gonna be more like 100. I knew there was a 1-0-0. It's probably 100 hours.
MARIA VARMAZIS
The Art of Design series on there, which I love. Yes, that I was excited.
CAROLE THERIAULT
Yeah, yeah, yeah. So that's cool. Now if you do have Netflix and you're like, oh, boring, I have another thing.
CAROLE THERIAULT
Yes, right. So the Faroe Islands I've never been. Here it's beautiful. However, no tourists are allowed on the island right now.
So what they've created is a remote tourism tool, and basically it works via mobile, tablet, or PC.
You can explore the Faroes' rugged mountains, see waterfalls, and spot traditional grass-roofed houses by interacting live with a local Faroese who will act as your eyes and body on a virtual exploratory tour.
GRAHAM CLULEY
And what, you go around the Faroes, do you?
CAROLE THERIAULT
Yeah, exactly.
So basically, the local is equipped with a live video camera, allowing you not only to see views from the on-the-spot perspective, but also allows you to control where you go, what you look at, and even walk, run, and jump.
So if you click on the link, so it's remote-tourism.com.
GRAHAM CLULEY
Okay, yes, I'm there right now.
CAROLE THERIAULT
Now you'll see it says the next tour starts at a particular time.
CAROLE THERIAULT
And each trip lasts for an hour, and people can take turns to be controller for 1 minute each.
GRAHAM CLULEY
Well, hang on a minute. So, oh, so this is actually— you're directing someone live? Go a bit closer to the cliff.
MARIA VARMAZIS
Yeah, I was just thinking is this gonna get really dark really fast or what?
CAROLE THERIAULT
I have a feeling she'll be like, no. Anyway, it's very cool, and it's quite fun.
MARIA VARMAZIS
So brilliant. That is honestly really brilliant. I love that. Yay, that's so brilliant.
CAROLE THERIAULT
Cool. Okay, well, all the links that you need, and there's a video in it, all that's going to be in the show notes, which is on our Smashing Security website.
GRAHAM CLULEY
Marvelous. Well, I think on that wonderful note, it just about wraps it up for this week.
CAROLE THERIAULT
Being dramatic.
GRAHAM CLULEY
Well, I was— yeah, anyway. So, Maria, I'm sure lots of our listeners would love to follow you online. What's the best way for folks to do that?
MARIA VARMAZIS
I mean, I guess Twitter. I'm not really online much.
CAROLE THERIAULT
She doesn't really want people following her right now. Well, I mean—
GRAHAM CLULEY
Keep your distance.
MARIA VARMAZIS
I'm out of work and caring for a kid full-time at the moment, so I'm not tweeting much of anything interesting while I'm chasing a 3-year-old.
I'm on Twitter @mvarmazis, but don't expect much right now.
GRAHAM CLULEY
And you can follow us on Twitter @smashingsecurity, no G, Twitter doesn't allow us to have a G. And you can also join the Smashing Security subreddit. Go and look for us up there.
CAROLE THERIAULT
And as always, many, many murky buckets. It's French, Graham, for listening to us. You keep Smashing Security alive by listening to us each week, literally.
Also, a huge thank you to this week's Smashing Security Sponsors: Boxcryptor and LastPass. Their support helps us give you this show for free.
Check out smashingsecurity.com for past episodes, sponsorship details, and information on how to get in touch with us.
GRAHAM CLULEY
Until next time, cheerio. Bye-bye.
CAROLE THERIAULT
Bye. Stay safe.
MARIA VARMAZIS
The gun is good, the penis is evil.
CAROLE THERIAULT
Is that a Zardoz—
GRAHAM CLULEY
Is that a quote?
CAROLE THERIAULT
Do you know why you love him? Because he's got, he's got a rather big package, doesn't he? He does.
MARIA VARMAZIS
The movie is batshit insane.
CAROLE THERIAULT
That's why I just want you to look at the images, the Zardoz images.
MARIA VARMAZIS
I've seen Zardoz so many times, girl, in various states of mind.
CAROLE THERIAULT
I'm just saying, he's very endowed.
MARIA VARMAZIS
That's just so not part of the appeal of the movie for me.
CAROLE THERIAULT
Well, he is trying to show it off quite a lot with his 1970s weird—
CAROLE THERIAULT
I'm going to get one for my husband.
GRAHAM CLULEY
I've just seen a picture of a woman.
MARIA VARMAZIS
The woman dressed up for Halloween?
GRAHAM CLULEY
Just, have you seen it? Have you seen that one?
MARIA VARMAZIS
Yep. What an outfit! I had a friend who introduced me to that movie, I want to say 15 years ago, at a 24-hour bad movie marathon at our local cinema.
And it became a yearly thing where we would take somebody new every year and we would just watch the person, not the movie, but the person, just watch their reaction as the horror comes over their face and they're like, what am I in for?
It's great. It's just great.
