A rapping bank worker is accused of stealing from the vault, the devices that can hide your car’s true mileage, and why it may be a case of “No No No” rather than “Ho Ho Ho” when it comes to IoT toys this Christmas.
And as Carole sups the mulled wine, Graham has problems with his internet connection…
All this and much more is discussed in the latest edition of the award-winning “Smashing Security” podcast by cybersecurity veterans Graham Cluley and Carole Theriault, joined this week by The Cyberwire’s Dave Bittner.

Frank doesn't like to talk so much anymore.
My name is Graham Cluley.
I don't want to go into precise details, but I've ended up in a fairly small room.
Now Graham is gonna tell us why you shouldn't assume that your social network is your private kingdom. Dave is gonna chat about an automotive man-in-the-middle attack.
I'm gonna be all ears. And I'm heading down the IoT toy avenue to see what potholes we should avoid. All this and loads more coming up on this episode of Smashing Security.
Getting a fox, yeah, saying, look, you've got a new job, come on, you know, act as security at the hen house. You don't do it. It's a disaster, isn't it? Dave, have you?
You wouldn't put a cock in the White House either. You wouldn't put a fox in the hen house. As simple as that. There's a very good reason they can't be trusted, right?
Foxes generally can't be trusted. Or rather, they can be trusted. They can be trusted to behave in a particular way. They can be trusted to do something very, very bad.
When I was in college, I had a roommate who was a pizza delivery man, and sometimes he would get hungry, so he would slice off a little sliver of one of the slices, and then he'd readjust all the other pieces to try to fill in the missing gap.
The FBI claims has happened in Charlotte, North Carolina, because a 29-year-old bank employee of the Wells Fargo Bank, he has been charged with stealing $88,000 from the bank's own customers.
You've basically given them money, haven't you? You're kind of loaning it to them really, and you hope that when you come back and ask for it, that they've still got it.
Well, yeah, so he was pinching this money, allegedly, I should say.
What he would do, one of his jobs was that people would come into the bank and they would bring in a big pile of cash, right?
So I imagine there are some businesses which aren't getting the money electronically, aren't getting it on checks, but are getting it in a big sort of wodge, right?
You get a great big bag full of cash, you plonk it down on the bank and say, thank you very much.
They just bring in a bag of cash and say, I want to deposit this. And the bank's machine goes counting up all of the money, all of the coins, working out what the total is, right?
And then the person behind the desk says, oh yes, that's, you know, £17,027. Well, no, it wouldn't be pounds and cents, would it? We haven't quite arrived yet.
You know, my bank account has been credited to that amount.
Now, Orlando Henderson, according to the FBI, was being a little bit naughty, and what he was doing was he would take that big bag of cash, he would put it through the machine, the counting machine, and then he would say to the person, "It's not $17,033.
Instead, what you've got here is maybe $10,033," and then he would take off the $7,000 himself.
So yeah, I would basically shove my pockets with any of the change that I got.
Now, it wasn't a lot of money, it wasn't a big fancy place, but yeah, say you'd gotten, you know, I don't know, $20 during that night, you would try and pocket 4 or 5 for yourself.
But we had to share our tips with the— I'll wait while Graham—
So, but we had to share our tips with the bartenders.
And I would tell you, at the end of the night, when you were there counting up whatever tips you got, those bartenders were eagle-eyed, looking over you, doing the math in their heads, making sure that you weren't shorting them.
Now you might be wondering, well, where's the computer angle in all this? Where does that, you know, because it's a bit of an old-fashioned fraud, this, right?
He would take the money, he would pop off down the road, and he would pay in lots and lots of money on a regular basis in an ATM to another bank where he had a bank account.
That's where he was siphoning off all this money which he was stealing. But where things began to go wrong for him was because he was a bit of a social media slut, right?
Oh, Graham started posting.
And if someone was very sexually active with lots of different people on different networks, you might say they were a bit slutty. So it fits.
So he was posting all these, but keep up the sort of Shizzle My Nizzle, Puff Daddy, Straight Outta Compton look, he was also fancying himself as something of a rap star, going by the nickname AC Fawazy.
He even posted a rap video, which I've linked to in the show notes, and we can check that right now.
And when they were trying to work out who might have been grabbing all this money and they went through the list of employees on Facebook and Instagram, there was this chap in front of these luxury cars pimping himself as some kind of rap star.
Literally with the money in his hands. And some of his buddies up on the social media was just— they were posting comments, and who carries that much money around with them?
Potentially, he could be jailed for up to 25 years if found guilty. The authorities are now investigating smashing security in this.
But once again, we find ourselves in this position of really as a sort of a service, I think, for the general public of criminals out there.
We need to tell them, look, if you're going to rob a bank, and in particular if you're going to rob the bank where you actually work, it's probably best not to brag about it and post photographs of the evidence up on Instagram and make rap videos about it as well, because something bad's going to happen.
Can I tell you a secret?
It's not that drink the Cristal is to show all your friends you're supping back the Cristal. Who's this friend of yours named Cristal?
Ronald Reagan is president. Drugs are bad. Drugs are bad. Yeah. And a middle-aged man named Bill Bittner decides he wants to buy a car. That man would be my father. Aw.
What a waste of money.
This is everything bad about 1980s Detroit automotive manufacturing in one beautiful two-toned package.
My father comes home with this car, the apple of his eye, the object of his desire.
The transmission fails, there's trouble with the engine, and he takes it into the service place and he says, "Please fix the car." And they look at it and they give it a once-over and they come back to him and they say, "Sir, we've looked at this car and the things that have gone wrong with this car do not align with the number of miles on the odometer of this car." This car claims to have around 40,000 miles on it, and the things that are going wrong, the amount of wear that we see inside the engine bay, this car probably has 80,000 or so miles on it.
This is a fly-by-night kind of place, clearly. So, you will recall back in the pre-digital days, this was a mechanical affair.
There was a cable that went from inside the engine compartment to a physical device on the dashboard that was the odometer. This is the thing that— Yes.
The digits roll over, and that shows how many miles there are on the car. And people back then would have to, they'd call it cracking open the odometer, to roll it back.
And this, of course, is a crime.
You're not allowed to do that because if you alter the mileage on the car, that could change the value of the car, which is exactly what happened to my poor sweet father.
So time passes.
Just a couple weeks ago, I was watching one of my favorite YouTube channels, which is called BigClive.com, and Clive takes apart electronic devices A very charming fellow.
And he had a device that someone had sent in to him, and this is basically an electronic man-in-the-middle attack.
It's a little device that goes on a modern vehicle's CAN bus, and the CAN bus is the controller area network.
That's the electronic communications bus that runs all over your car that communicates with all the different devices that need to talk to each other.
So what this device does is it takes the readings from the ECU, which I think is the electronic control unit. It's "wah wah wah wah" for me.
Now in modern cars, there can be multiple places where the mileage is stored, and this is to keep people from modifying the mileage, doing essentially an electronic rollback.
This value is stored in multiple places, and the ECU checks to make sure that they're all in agreement.
However, however, and here's where it gets good, however, the display on the dashboard is being sent a signal over the CAN bus from the ECU.
The ECU says, hey, display on the dashboard, this is how much mileage this car has. Display says, got it, this is what I'm going to show. Yes, there's a massaging.
It would answer back and say, yeah, got it.
And then in the meantime, it would alter that value lower it by, let's say, 40,000 miles and send that value to the display on the dashboard. Right.
So the car always knew the correct amount of mileage, but you, the driver, wouldn't. The brains of the car thinks that there's nothing going wrong.
It's communicating with the display and they're all talking to each other, and as far as it's concerned, everything's fine.
But this man-in-the-middle attack is intercepting that message altering it, sending it to the display.
So if now you go to, let's say, sell your car or get your car appraised for sale or something like that, the person looks at the display and it's much lower than it should be.
Sorry, I triggered— that was Siri. That was me.
So the display is now showing something that is inaccurate, but as far as the car is concerned, it doesn't know that there's anything wrong.
So on this video from BigClive.com, he basically reverse engineers this device. And what's interesting, it's not terribly complicated. You can buy these online for under $20.
And it's not that hard to install.
At this point in time, there'd be some sort of security on the CAN bus. And evidently, there isn't.
The CAN bus sort of trusts that anything coming from inside the car is trustworthy.
So anything you're going to have in the last 10 years, the systems are all going to be running, they're going to be slinging data around on a CAN bus for sure.
There are some things that have a higher level of security, like the anti-lock brake actuators, things like that. But overall— Oh, that's nice. At least a few. Yeah, yeah.
But the amount of security built into the CAN bus protocol is quite limited.
I think this is an area where they didn't think they'd have a problem, so maybe they need to take another look at it. Anyway, do check out the video.
It's interesting reverse engineering of this thing, and I thought it was quite fascinating.
So I'm so sorry.
Shall we just see what happens?
Okay, but seriously, I don't think it surprises me at all. I mean, there is a veritable glut of smart shit out there being marketed to kids and adults, right? With money to burn.
Phones and tablets and smart TVs and speakers and smart irons. I'm sure that exists somewhere. It must.
The question is, is it so smart of us to buy all this stuff without really thinking about whether it's safe or not? In fact, I'm sure lots of us think about it.
It's a whisper in our brain, is this gonna be safe? Yeah, probably.
I think maybe we probably give it a nanosecond more time than most people just because of the horrible things that we know, but then we just go on with our lives and do it anyway.
So we rely on her to do things turn the lights on and off and tell us when doors are open and so on and so forth.
And I know that even if people are worried and thinking, I probably need to look into this, but I don't have time, they're just going to buy the smart tech anyway.
So what I'm thinking is maybe you and I can share because Graham's not here because he couldn't be bothered to join us on this call.
We can share some advice on what people should look out for before they walk away with a cyber time bomb that's just waiting to mess up.
They're not necessarily au fait with making the technology or cybersecurity, right? That's not their wheelhouse. Right.
And this is this year, they've just put out this report. So there's this toy, this physical toy that Mattel makes called Bloxels, okay?
And it's basically a toy that allows you to build your own video game.
And there's an app associated with it, and there's also this web portal for consumers, like an education consumer web portal that was created, like you said, by a third party.
And one of the things that these guys found was that there was no moderation.
So kids could create games, put loads of inappropriate content such as swearing, which is what they tried, but you can, you know, to your heart's content, and then would put the game up there for other kids to play with.
The other problem was that accounts could be created with very weak passwords, right?
So that totally can destroy your entire security posture if you've got passwords that can be 4 characters long.
So basically, reputable, trusted toy makers have to really, really think hard about who they partner with to IoT-ize their toys, because faults on the connectivity side can lead to big headaches for your brand.
Yeah, and as buyers, we've got to be careful about what IoT machines we allow in our homes because we're giving this to the people that we basically love most of all to play with.
Rule number 2. Rule number 2. How smart is it, right? So what technology is it making use of or is enabled by default? So is there a Bluetooth connection? Is there a Wi-Fi connection?
Does it have a mobile app that's associated?
Are all these components necessary for the device or for the service you're trying to use, or can some elements be turned off or disabled?
If you think, for example, a mobile app, there may be settings that automatically turn on during the default installation, and I'd recommend you go look at those access rights, right?
Do you need to have a microphone as part of this thing? Does the microphone need to be turned on? What about the photo album?
Do you want them to have access to the photo album, to your contact list? And before you say, "Yeah, no problem," as soon as you click yes, they just hoover all that data up, right?
Every time afterwards, they just collect the changes. So think really hard before you say yes to those things.
So maybe, inserting yourself in that process to slow it down and say, okay, does your new Transformers Optimus Prime really need to be able to download the entire family's contacts list?
That's what you should do, right?
For me, the most important would probably be, can it get updates? Like, is it even physically possible for it to get some software updates? And how would that work?
What do I have to do to make sure that happens? Is it on by default? Is it not? Whatever. And then does it have any user authentication, right?
Like when I plug it in and give it my Wi-Fi, does it say to me, who are you?
And what secret word or secret handshake can we use to make sure I know it's you other than just your name?
Because as we talked about, if it's only limited to 4-character PIN code, right? So those are the big ones I think of. Two more, two more, and we're done.
But you can interrupt anytime, I don't mind. Okay, this is the big one and the hard one, but what information is being collected from your kid, right?
Or what is being shared with third parties? So we live in a bit of a tech wild west.
I know I keep saying that, but even tech daddy Google, you know, the ones that are basically paving the way for everyone else and setting the ethical standards for how we should use computing, was fined $170 million squidoodles to settle with an FTC accusation that they were violating children's privacy on YouTube.
You get well-respected companies like LeapFrog, this was just in the summer, which had serious vulnerabilities in their LeapPad Ultimate tablets that could allow a hacker to track the location of a child and then talk to them through the device's built-in chat called Pet Chat.
She's a fraud expert at a company called Terbium Labs, and she was making the point that when it comes to kids, parents might want to consider coming up with sort of false aliases for their children to use to log on to these things because that way you can try to delay or head off this aggregate data collection that's happening with all of us, where these people like Google and Facebook are collecting these dossiers about all of us.
If you can delay that for your child, that might be a good thing to consider.
So when you're putting in your child's name and those sorts of things, maybe you could even make it a fun thing with the child to come up with some sort of fun name that's not their own.
I'm being a bit doom and gloom here, right?
But it's the other information that annoys me, all the secret information they're hoovering up from your location, for example.
So say it's a tablet that your kid takes around with them whenever they go, and you've allowed an app on there that's allowed to hoover up all your navigation information, information that is taken from that thing.
And that's not something you would think about unless you read the T's and C's.
And you don't have to read all the T's and C's, if you were just to do one bit, right, you just go read the privacy notices.
Because what you're looking for is what information are you taking from me, how is that information stored and used, and who else will have access to this, if anybody.
Those are in my view, the biggest questions.
Are you willing to take that heat? Are you willing to live through that tantrum?
So as you have kids, I'm gonna give you my old school examples, right, for old school cool suggestions.
And I want you to tell me whether you think it'll work with your kids, okay, or kids you know. All right, option number one. Yeah, mix cassette tapes.
Now you may not know, but I am on trend. They are seriously making a comeback.
So if you can find your teen some old blank tapes and a working boombox as long as the tape recording component works.
And then they have to try and make a mixtape from radio we did in the '80s, '80s style. Did you ever make these when you were a kid?
There was no internet back then, so we were making mixtapes and passing them around, and you just sit by the radio, just— well, you're waiting for your favorite song to come on because you couldn't afford to go buy it at the record store.
So you— yeah, absolutely. Oh yeah, yeah.
But what's been going on? What? Oh, Graham, welcome back! We were just talking about you. Hey, I've taken over.
Yes, I'm just almost—
Which a Twitter user actually suggested to me that I buy for Graham. But as he couldn't even be bothered to listen to my story. No, I could be bothered.
But I think if you were to give a child a salt and pepper shaker shaped— I mean, that's, that's you're gonna lose your cool aunt, street cred. Yeah, I will very quickly. Yeah.
What about experiences though?
If they were into food, you get them a cooking class, or if they're into eating, you book them a table somewhere and chef it up a bit? Absolutely. I that kind of stuff.
And when you scrunched it up, little bits of crickets went everywhere.
One, you're probably gonna get a new device that needs to be connected to the internet either at home or in the office.
And two, if you don't use a reputable password manager, you're very likely to forget your passwords when you get back to work. So why not check out LastPass?

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.
Maybe one of the ultimate Christmas movies of all time.
Hello, Harry.
Harry said to me, he said, he's Irish, by the way, he said, "Oh, Graham Begorra, you should make your pick of the week this thing on Netflix which I've seen." And he pointed me towards a Netflix series called The Movies That Made Us, which takes you behind the scenes of fabulous movies like, I don't know, Home Alone and Die Hard and others I can't remember at the moment.
It tells you the stories of the movies, and it's fairly light and frothy, but at the same time quite fun.
And so I thought, as it's Christmas and as I like Alan Rickman, I should watch the episode about Die Hard. And I found out facts I didn't know.
For instance, Die Hard— did you know Die Hard was originally written under a different name way back in the 1960s, and it was a sequel to Detective Oh, for goodness' sake, I haven't got that written down.
It's something like No One Lives Forever. It was something like No One Lives Forever or something like that.
Anyway, it was the sequel to another book which was turned into a Frank Sinatra movie.
So Die Hard is actually a sequel, and Frank Sinatra owned the rights to the sequel to the movie which is in— so the sequel which became Die Hard, right?
And so when they eventually got around to making this movie in the 1980s, they were contractually obliged to give Frank Sinatra first refusal on starring in the movie.
I love Weekend at Bernie's.
And he's obviously a friend of the producer or something who's in the movie, and somehow John Barryman as well. But yes, anyway, back to my pick of the week, Carole.
We'll come on to Shark Attack. Oh yeah, back to you, of course. So the series is called The Movies That Made Us, and it's quite entertaining.
And you find out all this stuff like Sinatra turned down the job, as did Burt Reynolds and Mel Gibson and Arnie and Sylvester Stallone.
And they were very worried about the movie because it had all these jokey bits.
But the biggest problem of all was, of course, Bruce Willis, who was considered this sort of jokey, arrogant, smug sort of Moonlighting character.
He is a musician and he knows his stuff. He knows music theory.
And he goes through a song and just deconstructs it, tells the audience what's going on inside that song, what's going on musically, what's going on lyrically.
What's going on with all the different instruments that are being played in the song, the structure of the song, and the way that he does it is so joyful.
He just loves everything about all of these songs that he talks about, and it's a contagious enthusiasm. He's done a variety of songs.
He's done everything from Think by Aretha Franklin. He did Like a Prayer by Madonna. He's done songs by—
I don't mean to bring security up in Pick of the Week, but come on, dude. You could just email him and say, dude, I'll show you how. I'll show you how I have friends.
If only we didn't have episode 159 of Smashing Security after how this has been.
And as the holidays, and many of you will be hiding, no doubt, from the in-laws and the like, I thought I would give you something to distract you.
And this is Apple TV's show called Truth Be Told.
And the reason I've chosen it is because we, Smashing Security, will not be recording for a few weeks so we can recharge our batteries for 2020, because God knows Graham needs it.
But I thought I would check out a podcast-related series that would maybe tie you guys over until we return to the internet waves. So it's called Truth Be Told. Here's the premise.
So Poppy Parnell— okay, snappy name— this is played by Octavia Spencer. She's a true crime podcaster returning to the case of Warren Cave.
This is played by Aaron Paul of Breaking Bad fame. Warren was convicted 20 years ago of murdering his neighbor when he was only a teen.
Now Poppy, our star, has reason to believe that Warren might be innocent, but she's also got skin in the game because basically she got famous, you know, she wrote a series of stories that made her career, and she's concerned that her reporting led to his conviction.
So that's the story. So I thought, okay, that's kind of interesting, right? I can identify. I'm a podcaster. I like crime stuff. Great, right? But I don't know if I recommend it.
It's that kind of pick of the week, isn't it? 4 hours watching it. No, I spent 4 hours listening and I felt I would do a review, okay? Because it turned out—
There's a lot of that stuff going on, and there's all this Scandi Noir music, you know, deep and meaningful and hopeless and echoey.
You're constantly dealing with her feelings of guilt and her family's lack of support and her passion, you know. But I kept watching it, okay? And it's not even finished yet.
New episode comes out every Friday. I've watched about 4, and I think I like to scoff at it because she keeps missing the mark of what makes a great story in my opinion.
So if that grabs you as fun as a Christmas activity, check out Truth Be Told on Apple TV.
I've not really seen anything to make you click your heels. But, you know, watch this space.
She's several episodes in. I only watched the first one so far, and it was pretty good.
It was good enough that I would watch more of it, but I don't know that it'd ever actually be my pick of the week or anything.
And what's the best way for folks to follow you?
I'm the co-host of the Caveat Podcast. Sometimes I appear on the Grumpy Old Geeks Podcast. Really, at this point, there are more podcasts that I host than I do not host.
So, and after our little time together, I think Carole and I have agreed that I'm gunning for you, Graham. So next, no, it's much nicer to me, Graham.
Go and find the Smashing Security subreddit up there.
How will we survive the next few weeks without you? Lord only knows. But we wish you at least a tolerable Christmas season and a wonderful night to bring in the new year.
