Now let's get this show on the road.
That's all it needed was a firm—
Hello, hello, and welcome to Smashing Security episode 195. My name's Graham Cluley.
He's a TV producer, presenter, technology journalist, and car nut. It's Jon Bentley.
And it's good fun to do. It's great. And we don't take ourselves too seriously. I don't think it's just stuff about new technology.
1989, roughly, I think, somewhere around there.
Now, coming up on today's show, Graham makes a new Facebook friend. I know. Jon talks about how Mercedes is ramping up its security in its fleet.
And online school is back in session for many. So let's review the main threats and how to handle them. All this and much more coming up on this episode of Smashing Security.
Carole, I remember sometimes going round for late-night soirées at your house and there'd be someone there, or maybe me, who'd want to go and we hadn't got the hint and— Well, you tell people what you would do.
It started off well, but it's had a bit of a lull, but I'm sure it'll come back.
Facebook users have been passing around a warning that a lady of that name has slipped into your friends list, rather like slipping into your DMs, without your permission.
And the warnings are saying that Celine Delgado-Lopez has managed to friend just about everybody on Facebook, despite there normally being only a 5,000 friend limit.
I don't actually use Facebook terribly actively, but I am on it, I think, and I'm searching desperately now to see whether Celine Delgado is one of my— and she isn't.
I mean, I've been left out of this.
Well, according to the warnings, which have been spread via direct messages and public posts and even other social media, people are saying, why am I friends with Celine Delgado Lopez?
And other people saying, my boyfriend's just shown me a Facebook post. Everyone is friends with this woman, Celine Delgado Lopez, and you can't unfriend her.
The only option you have is to block. And what people are saying is that when you look in your friends list, right, on your Facebook account, you don't see her listed.
But if you go to her profile, if you search for her on Facebook and find her profile, people are believing that she is their friend.
And so people to find out if she is their friend go to her profile, they look up her profile and they discover that there is no option to unfriend her.
All they can do is message her.
They search for her name, they go to her profile, and when there, they see there is no option to unfriend her, but they can message her, whereas normally there's an option to send a friend request.
And so they think, oh my goodness, how long have I been friends with this person?
There have been videos created investigating the mystery of Celine Delgado Lopez, which have had millions of views.
So the rumors are going around and someone suddenly mentioned, hang on, there was a Mexican TV show running on the station Canal 5 decades ago, all about missing people.
And one of those people went by the name of Celine Delgado López. And people are going, what is going on here?
Now, I don't know that that's necessarily that unusual a name in South America. It seems like it could be a name, you know.
They started at 3 o'clock in the morning posting spooky videos onto their social media accounts, which were of a ghost speaking or something like this.
So people began to think, well, maybe this is connected to the missing woman and to all these Facebook friend requests because we saw that earlier in the year.
Well, what's really going on is that people don't understand Facebook privacy settings because you can disable the ability for people to add you as a friend on Facebook.
When I did have a Facebook account, I disabled the ability for people to send me a friend request, right? Because I thought, well, who would ever want to use that? First of all.
Is that what you're saying?
Because this particular profile had disabled that ability, when people went there because they'd got the scary warning, they saw there was no button to add friend, but only to message her.
And so people assumed that meant that she had already friended them. So people didn't bother checking their own friend lists.
All I tend to use is as— I think of it more as a useful way to provide information about what's going to be in the programme this week or something like that.
They're assuming that she's sort of cloaked herself. She's in stealth mode.
I have no proof, but I'm sure of it." Well, come to 2020, Carole.
And because your friend has warned you, you believe it.
That was the whole premise of that, wasn't it? I receive a lot of friend requests from people.
I have to try and assess whether they're really real or not, which sometimes I don't think they are.
I noticed I would then receive adverts of very unflattering pairs of jeans on Amazon whenever I went. They obviously had my demographic sorted.
I mean, I remember years ago, Carole, we worked on the Naked Security site and a mainstay of my output writing articles in there was Facebook hoaxes and clickjacking scams and viral stuff which was spreading on Facebook.
It is extraordinary how much people will believe when they receive it in a fancy font on Facebook. So you might think, well, what's the real danger of this other than wasting time?
But if people really believe that this woman is somehow secretly linked to their account and they can't unfriend her, they might then fall for a follow-up scam which says, click on this link to unfriend her or go through this process.
We just need to get off the site.
The new version coming out next year in 2021 will finally feature full over-the-air software updates.
I mean, you could say this is sort of 8 years after Tesla first featured them, but now the fact that Mercedes are adopting them means they really are entering the mainstream of legacy car manufacturers.
I think it is a real issue as cars become more and more complicated and more and more connected, their security systems really aren't up to scratch at all.
And Tesla had the right idea because they were starting from scratch with being able to basically keep a car up to date like a computer is kept up to date.
But other cars are quite weak in this regard, I fear.
I wouldn't— don't quote me necessarily on that, but I think it's much more limited.
BMW recently, because they're quite ahead in this field, I mean, they work in whatever the consortium is that does digital car keys with Apple, as they were the first to announce their involvement in that.
But their focus when they announced in July was more on the fact that you'd be able to pay for your options remotely.
So the car may be physically equipped with having heated seats, but you'd only get them if you paid extra and then they'd be activated remotely through software, which sounds potentially rather wasteful, or it could be very efficient if you think every car's the same, therefore it's easier to build, whatever.
But there's— I think it's more the fact that cars are really rather insecure.
I mean, all cars have been connected to the internet since 2018 through the eCall system, which is when you have a crash, all new cars have been connected.
It could save your life.
It could be a wretched nuisance if you were hoping not to go through the insurance company for that careless bit of parking, which happened to set the airbag off.
But they're all being connected.
So that makes all cars potentially really very vulnerable to, I mean, theoretically, if once a hacker's got into the in-car entertainment system, they could get through to the steering and the brakes of the car.
If it has automatic parking, for example, there's already a link in the car so that you can actually get through to those parts of the system.
It's theoretically possible that, you know, all Range Rovers could be forced to turn left at 11 o'clock on Friday or something.
It's also possible that you could get ransomware threats over your in-car entertainment.
I mean, we have seen security researchers demonstrate some of the vulnerabilities in cars, including taking over the steering or the accelerator, or maybe more simply unlocking cars remotely.
And finding out where they are. I guess Mercedes has been a top brand. They're probably doing loads of stuff, are they, which is going to be possible to do via updates?
I think since they've regarded security as very much a physical issue, locks and keys and that sort of thing.
But I think the fact that Mercedes is now getting involved and that they seem to be stressing more the comprehensiveness and security aspects of this is good that everyone's catching up with Tesla.
So actually it's not necessarily, although I'm pretty certain the market's taken a hit, but it seems to be bouncing back.
Jon, as someone who's clearly a huge motoring enthusiast and also into technology and gadgetry and so forth, do you think sometimes too much technology is being put into cars, or is there no such thing as too much technology?
I'll give you an example. I've seen the new Honda e, which is their new— right? And they have a digital aquarium.
And merely to get your finger anywhere near a touchscreen and to actually prod the right bit of it whilst you're driving is very difficult.
And I know that there are— There are attempts, I know Jaguar was trying to do this, to actually monitor the position of your finger in advance so that it can somehow tell what you're aiming for.
That's not so good, is it?
I can see that you're going to be torn in two directions potentially by this because you clearly love your cars and motoring, and you clearly love technology.
So where do you stand on driverless cars? Is that a good thing? Are you looking forward to driverless cars, or is there a bit of you which thinks, I want to drive?
Maybe that would be one good way of looking at it.
I think the interim is a real problem where you get sort of semi-driverless cars and it becomes very difficult to remember which things you're driving can do and which you can't, which is one thing.
And also they will be lulling people into a false sense of security, which you do get with Teslas already, for example. You know, people think it's genuinely almost driverless.
They're delighted with the fact they've done 20 miles of motorway without squeezing the steering wheel, then all of a sudden they encounter something.
Something— you're told to take over. Maybe the car can't handle that bend or whatever. It just takes so long to get back into the zone of concentration and you'll crash.
This guy had a big camper van, you know, bed in the back, set his cruise control, went to sleep.
It seems like some are pretending the pandemic was a pre-summer problem, while others worry that some of us are getting a little less vigilant and that we're going to see infection numbers shoot skywards, right?
So it's really fascinating. I've got friends in different parts of the world, and they all are dealing with the same issue. And it's— they're all going, why is it changing?
Anyway, so everyone's kind of wondering what's going on.
Now, according to SecureList, half of all US elementary and high school students will be entirely online, which surprised me.
Even those that are reopening are deploying some kind of hybrid model, such as delivering large lectures online. And I mean, I feel for students and the teachers.
It's got to be really hard, right? Not everyone's good at performing online or learning online.
They have to use Microsoft Teams or Google Classroom. Actually, my elder daughter was also doing some dance teaching.
So to have all this going on with me trying to record YouTube videos in the house was— How dare they?
It was more the cacophony that was the problem rather than the— All the education was going quite well, I think.
So the thing is, maybe if you were a parent or a teacher, as we listen and go through this story, I'm going to try and cover a few things that have happened since school reopened in the digital world and things that we can do to make sure that you don't get stuck into one of these.
And I'm not just talking about the embarrassing things that happen, you know, you thinking you're on mute as you let out some loud body expletive, or you forget the cameras are on when you bend over unattractively, or a parent comes in or whatever, all those things.
So we're going to start off with Zoom bombing. We've covered Zoom bombing. This is a word that didn't exist in 2019.
Is that— I wrote that down and I'm thinking, is that a fair statement?
So we have Albany High School last week during an online freshman orientation session was disrupted by people who drew obscene pictures and engaged in racist and sexist speech in a chat function.
And apparently this happened because Albany orientation included parents, so people with non-school email accounts were admitted to the call.
There was a school, a middle school in Columbus, Georgia, suffered a similar online snafu last Wednesday when their social studies lesson suddenly became a skin flick.
Parents— one of the students said the daughter said she saw what looked like the Exorcist's face before the class video system was flooded with inappropriate images.
And there's even San Leandro 5th year class video session got disrupted by what they're calling inappropriate and possibly pornographic images.
I found that term so weird, possibly pornographic.
So in June, Microsoft Security Intelligence reported that the education industry was getting 61% of the 7.7 million pieces of malware that hit enterprises in the last 30 days.
So for every 10 pieces of malware that hit a company or corporation or an organization, 6 were hitting the education sector. But it's not just Zoom bombing.
DDoS attacks, this is a distributed denial of service attack, is on the up in the education sector as well, as much as 350 to 500% greater this year than it was in corresponding months in 2019.
Another major university in northeastern U.S. had its exams disrupted after a DDoS attack, you know, affected its online test platform.
These are packages that are available online and people are maybe Googling and clicking on maybe ads for these things that may not be going to the appropriate places.
But they're bundled into legit installers, right? So in 2019, Kaspersky said that saw less than 1,000 unique users who'd been impacted. But in 2020, it's already jumped to 170,000.
So that's just a quick list, but I thought maybe we could just take a bit of time to just mention a few things that you can do or make sure that your school is doing for your kids to make sure they don't end up in one of these situations.
Because a lot of this stuff happens in phishing accounts too, right? So you're getting phishes which are saying, hey, download this Zoom app and get, you know, some incentive.
And that's the way that a lot of these are coming to people.
I mean, you hear about things being routed through China and things— Zoom sharing user data with Facebook. Is that all fake news?
But they seem to have changed their spots. They appear to be making more of an effort. So they're—
I don't agree.
It is a doddle compared to Skype, which still, for the life of me, I get into a pickle every single time.
So I think that the ease of use is what's given it edge, but give me a break that a new company compared to someone like Microsoft would take security or have the same kind of gravitas when it comes to security.
Zoom is still trying to grow and be a market leader. It's now having to start to contend with, now that you are market leader, we're now going to look at you. Oh, wow.
We found a lot of problems. Like, it was like, oh, this is not very good Zoom. And, you know, to your point, they have made some of those changes.
It's just that the media hasn't been talking about them because everyone is talking about Zoom because that is the one that most people are using most of the time.
So we ended the session here, and of course we never covered a few quick tips that I wanted to share with you to make sure you guys had a safer online session.
So password protect your video sessions and share those passwords very carefully. Ask teachers to admit attendees as appropriate rather than letting it be a free-for-all.
And what you can do is have people register beforehand with their email address so teachers can kind of cross-reference those to make sure all the people that are appropriate are let in as opposed to other people.
Make sure that the school provides easy-to-follow links to the bona fide real deal video app.
We want people to avoid downloading video apps that also have malicious code tagged onto it.
So if you provide links, easy links, and advise people to download the video software from this link, you increase your chances that people are actually using the real deal and not installing suspicious software on their computers at home.
And tell your kids not to share private information, though most of them know that now, not to respond to contact requests from people they don't know, and who they should tell if they see or hear something upsetting or inappropriate.
That's really important. Always say this is the person you go to. Hey, Carole, that was really good. That was really, really excellent advice. Thanks for sharing that.
Oh, no problem, Graham.

And you join us at our favorite part of the show, the part of the show that we like to call Pick of the Week.
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.
This is an article, you might be thinking, oh, I wonder who's written this article? Well, the article is written by GPT-3.
And that is this extraordinary new AI system, which has been used in all kinds of ways.
And so it went away. And a typical robot, it disobeyed because it didn't provide a 500-word article. It produced something which is about 1,200 words. But never mind that.
It is a bit too much. And it is well written. It's slightly scary because you think about the implications of this.
It tries to reassure us that it doesn't have any plans to kill us, but at the same time—
What on earth is going on here? So it's rather petrifying.
I think I've tried to— I can't remember which— where exactly they were from and which ones were best. But this seems slightly more convincing. I'd to see the raw output.
It's like world-endingly, cripplingly scary. What do you do?
I mean, we had the Echo early on and obviously tried it out, and my wife was delighted that she could summon up radio stations quickly and everything, all that sort of thing.
But then it started answering back.
Although I do occasionally, obviously I have them and I switch them on to do things. And it's also a bit the same with the light bulbs as well.
They're fine until they decide to reset themselves when they all come on. And if there's been a power cut or something, their default position is on, which is always annoying.
They, and often you can end up, the app's crashed or whatever, just becomes an awful bit of a palaver.
And I end up using the IKEA disc instead and switching off the hub and things like that. So I've got a bit of a love-hate relationship with IoT things really.
So I think we have to be careful.
I mean, I was tempted.
We were doing some filming with it, it's not quite, it's a few weeks old, came out a few weeks, months or so ago, but that Sony ZV-1, or ZV-1, it sounds better that, vlogging camera.
It's great to see that camera manufacturers are starting to take vlogging seriously and providing flip-round screens and microphone inputs and very clever autofocusing it had so that you would set it to face autofocus so you could be doing your vlogging, focus automatically on your face.
And if you held up a product, it would, if it was in product demonstration mode, it would automatically shift focus from your face to the product and back again, which I thought was pretty good.
In the end, I thought it was— I went to visit the very much reduced IFA at the weekend for a Gadget Show piece in Berlin, and it was just a few little things there.
And the one I rather liked was a thing called the Heapl, which was a mini induction heater that can be built into your kitchen worktop.
Admittedly, it's a prototype at the moment, but so you can just plonk your cup on the surface in the right point and you get boiling water very, very quickly.
But you do have to put in a sort of wand first to attract the magnetism, a metal wand. But it's rather an induction hob, but a mini one for boiling drinks. So I quite that.
I was also hoping to squeeze in a mention of the new series of The Gadget Show, which starts on the 25th of September, 7 PM on Channel 5. Excellent. Yes.
Oh, but also in our prize fund this series, we've also got a copy of my book, Autopia, on the future of the car, which came out last November, comes out in paperback, a slightly revised form, on 1st of October.
I thought I'd try and get that in as well.
I have a rather massive husband in terms of size. He's 6'4", right? 16 stone. Big, big T-bone of a man.
Well, it's not equipment, but you know what I mean. He doesn't, but he has been getting into biking, right? And he's a bit of a tech nut like you.
So the other day I was perusing Costco.co.uk, which is, if people haven't been there, it is coming on in leaps and bounds.
What a fun afternoon you can spend checking out what's available on Costco.co.uk. Okay, that's how bad it's got. But let me send you this link for this bike.
And I want to just get your take on this bike. So it's called the Rayvolt Cruiser V3 e-bike with lights, mirrors. That's nice. At least, you know, and a leather bag.
And you can get, I mean, you can get kits to convert other, your favorite bike to electric now, which I quite like.
But it must weigh a ton.
I'm sure lots of our listeners would love to follow you online, maybe find out more about your book as well. What's the best way for folks to do that?

So you guys notoriously— I don't know if you still do this, I haven't seen it in a little while— but you guys always gave away the most ginormous list of freebies.
You people have not seen this show who have no idea what I'm talking about, we will find a YouTube link to show you how much, or something, so you can see.
On average, there's what, 50 items?
On average, I haven't seen the latest surveys, but when we did a survey early on, people tended to keep a third of it, give a third away to friends, and eBay the final third.
So it was so much, because they simply wouldn't have room to keep it.
But yes, also in our prize fund this series, we've also got a copy of my book Autopia on the future of the car, which came out last November, comes out in paperback, a slightly revised form, 1st of October.
I thought I'd try and get that in as well.
