I'm actually broadcasting from my wife's knicker drawer because the kids are being ultra loud downstairs.
So what's happened is I've hung up a shirt in the cupboard I'm in and it's fallen down, hit my tea, and now I'm standing in a pool of tea. So it's going well.
Hello, hello, and welcome to Smashing Security episode 240. My name's Graham Cluley.
We are joined by someone who I believe is the BBC's first and maybe only cybersecurity correspondent, Mr. Joe Tidy. Is that right, Joe? Hello.
Well, at the moment, yeah, I'm the first and at the moment I'm the only one, but the way things are going, there'll be about, you know, there'll be a team of 100 of us soon.
So there's a gender and identity correspondent, there's a population correspondent, an Africa religion correspondent, and then there's cybersecurity, or cyber, as I changed it.
About 6 months ago, I changed it to cyber so that I could do other stuff as well, like, you know, things like gaming and, you know, that sort of thing as well.
'Cause when you do a gaming story, for example, putting cybersecurity correspondent as your byline is a bit weird.
I've got something about the chaos in cryptocurrency exchanges, why on earth they are being hacked all the time and losing hundreds of millions of dollars.
I'm going to name 4 things, and I would like you to tell me which of the following is real and which are fake. So which is which, right?
I have the carbonara constable, the spaghetti detective, the taramasalata traffic warden, and the Pizza Police. It's not from some new version of Cluedo that I'm getting these.
Which of those do you think might be real and which might be fake?
Because I am talking this week about 3D printers. Do either of you own a 3D printer, or have you played with 3D printers?
I need to go and get my face or something printed for a piece to camera, don't I? It's gotta be done.
And it's the nozzle which moves very precisely, you know, X, Y, but not just X and Y, but Z axis as well, under the control of a computer.
And molten plastic, a polymer, is squirted out, cools down, and then some more plastic is squirted out, hopefully sticking to the previous piece.
It's a bit like doing icing on a cake, Carole.
Some people are really excited about the potential for printing 3D spare body parts.
So if you feel, oh, you know, my right calf isn't quite impressive enough, maybe you could get it replaced with a 3D part, or if there's a valve or something, or if you were on an International Space Station and you needed something, you could print it out.
If you've got a cheap and nasty 3D printer, it might break down or catch fire— I think the fire hazards are sometimes a problem— it can make a pretty awful smell, and it's not uncommon to encounter 3D-printed objects that haven't quite come out as planned.
Then when it squirts out, when it extrudes the polymer, it may fail to attach itself to the existing model that's been made.
And you end up finding out that you have basically a pile of plastic spaghetti.
And because all the different components are built together, so it's very slow. It's just layer by layer by layer.
And if it detects that something has gone wrong, with the AI through the webcam.
For instance, if it starts extruding spaghetti, the Spaghetti Detective will interrupt the print job, will stop it, and send you a text message or an email saying, you might want to, you know, you might want to try again with this, something's gone badly wrong.
So it's very clever. And this Spaghetti Detective toolkit is open source. So if you've got the nous, you can set it up for yourself on a server. And off you go.
If you've done 3 inches and it starts screwing up, it stops it. You're gonna have to start again. But I suppose you don't have to wait till the whole thing is built.
I imagine this doesn't work very well if you are trying to 3D print spaghetti because it'll keep warning you, hey, you're making spaghetti.
And so maybe you want to use a cloud-based service to do all of this for you, like thespaghettidetective.com.
But many people probably we'll pay them a little bit of money in order to have this sort of surveillance going on, which is kind of handy. What could possibly go wrong?
Well, last week, a Reddit user called OKRUB499—
So it's all sort of raised in the polymer. He hadn't set off a job. And it said, "TSD is not secure. I randomly connected. Sorry, had to inform you." Written in the plastic?
Written in the plastic.
Now, TSD is, of course, the Spaghetti Detective, and it turned out that the Spaghetti Detective contained a security vulnerability that allowed users to link to other users' 3D printers via this cloud-based service.
So not if you had set up the Spaghetti Detective yourself, but if you'd used Kenneth's spaghettidetective.com service.
And he says, if you're looking for lessons to learn from how they responded, take note that he never said, we take your security seriously.
He didn't excuse himself by saying, at least credit card numbers weren't affected.
And he didn't downplay the bug because it was only present for 8 hours and apparently affected fewer than 100 people. So it wasn't the world's biggest problem. It wasn't huge.
But actually, when you read— and again, we'll put in a link in the show notes so we can read the full analysis of what went wrong as posted on by the Spaghetti Detective on their site.
It's really impressive because they're completely transparent. They say, they actually call it a stupid mistake. They say it was horrible. They offer their sincere apologies.
They say, "We screwed up." Hallelujah.
But it was an embarrassing one, and I can't forgive myself for." I the way he's gendered the AI.
And they got printers around the world to print out, "Subscribe to PewDiePie's." Do you remember that?
And it was such a strange and weird, interesting story.
I think they did about 50,000 printers in the first wave and then they did about another 150 in the second wave and then they went into hiding and got really scared.
And now I talked to this guy who's really proud of it and, you know, he's tried to make me do a story sort of outing his identity many times and us sort of saying, mate, you know, just because it was a meme back then doesn't mean it's not a security issue.
You might still be in trouble for this.
But I think we can sort of turn a little blind eye to that on this occasion because it was— the vulnerability was only present for a short time.
About, I think it was last week or week before last about this $600 million hack of the cryptocurrency exchange service, the Poly Network, which in itself was an amazing story because of course all the money was stolen by the hacker who then proceeded to pay himself in Ethereum.
And every time he paid himself little bits, he would write a note, which is publicly available to everyone.
So he started by bragging about the hack and then he started saying, how can I launder this money? And then he changed tack and said, actually, it was all a security exercise.
I'm gonna return it all. And he did, which is amazing in itself.
But then of course, within a few days, you've got another hack of a Japanese cryptocurrency exchange called Liquid, and that's $100 million gone.
And then I've just been looking into this and it's just an absolute mess.
So there's this list I found on a website and I haven't verified these numbers, so I can't do the whole BBC thing.
Well, I will do the whole BBC thing and say this is unverified currently. But I'm gonna put this all onto a, sort of pen to paper and try and write something on this.
So I'm basically using you guys as a help for my article. So this is in 2020, there was one called AltBit, which had $70,000 hacked out of it.
November 2019, South Korean one called Upbit, $51 million. Then in the same month, $500,000 was lost. Then there was one in Singapore called BitPoint, $28 million.
And then in May that year, $40 million. And then of course there's the Coincheck one, $560 million worth hacked.
And then there was, of course, the big one, which is one that's probably the most famous one, which is Mt. Gox, which is $460 million.
But I didn't really know about this kind of problem until the $600 million recent story. And it is just incredible.
Your mind boggles at how this can happen, because I've been speaking to loads of the people who are caught up in this, you know, the victims.
And you often think, in the tech team, we kind of look at these stories and we think, oh, you know, does the average person care about this?
Because these are kind of crypto bros who have lost a bit of money speculating and gambling in the crypto world.
But then I spoke to this other person who said that their mom and dad, for example, had one bitcoin in the Liquid exchange, which they very nearly lost and they had to sell rapidly as a panic sell.
And now they've lost loads of money on it. And that was going to be their kind of little retirement pot.
So I just think it's amazing that these exchanges are custodians of so much money, yet they seem to be really badly secured.
And they said that all of our cryptocurrency is stored in cold storage, which means it's not directly linked to the internet.
Yet now it appears, and we still are waiting to hear back from Liquid, so I don't know the full facts, but it appears that wasn't the case.
And what I find amazing about this world, I don't know if you guys are into your crypto, but it's really hard to find people to speak about this in a level-headed way.
Because if you're an expert in crypto, then there's a good chance you're a crypto fan.
So as a reporter, I find these stories so intimidating to do because you're sort of dipping into a world that is almost cult-like in a sense.
There will be many people who will have put away a little nest egg thinking, well, it's worth us chucking £20,000 or whatever it may be in there to see what happens.
I think lots of people don't know how to get it out now and they'll be like, they'll get around to it, they'll get around to it, they'll get around to it.
You know, it's probably going to still go up - it's a marvellous way where you can actually go and find nothing in there.
And actually I recently found it and it's sort of 0.001 bitcoin. You're lucky. I don't really know what to do with it, you know.
And the funny thing is in my job, and it's probably the same for you guys as well, the only way to truly understand these things is to get involved and to use it.
And, you know, buy things and move your money around and stuff. But yeah, it is quite hard - it's quite a close-knit community, which is sort of a closed community full of weirdos.
I'd love - I mean, that's gold for people, right? To understand what they're getting involved in.
So we all chipped in and got him an NFT, a non-fungible token, just for a laugh. And it was delegated to my colleague Christina to actually go and buy the blooming thing.
And she must have spent three weeks trying to, first of all, buy this. Was it Ethereum or Ether?
I can't remember what the cryptocurrency was, but the faff she went through to get this, to actually secure this NFT, this useless bit of digital— And then she wrote a piece about it and it was great.
It's that sort of thing that shows you—
The money that— did you see that about Beeple, this digital artist who made $70 million, I think it was?
So Hulk and Linda Hogan, 2007.
The celebs that didn't follow suit are the so sweet and earnest you want to vomit— Can you guess who I'm talking about?
According to The Times, tech billionaires have typically divorced very quietly behind closed doors, and it's rare that they're willing to trade blows in a public courtroom and expose the complex web of their personal finances.
Makes sense. But they do happen. And just this week in tech and mainstream media, it's all abuzz with this high-stake tech divorce.
So in the left corner, we have robotics guru and startup entrepreneur Scott Hassan.
He was one of the code writers for the original search algorithm for Google known as BackRub back in '96.
He's kind of known as the third unofficial Google founder in some circles, along with Larry Page and Sergey Brin.
You know, before we all had phones in our pockets, you'd have video conferencing, and there'd be a screen on a long kind of neck, and it had— almost like those IVs in hospitals.
It looked like an IV, but it had a screen on it.
And it's a screen you bring in, like video conferencing, but it would be keeping at the height of the person.
So you could bring it down to be chair height or standing up, so you could have a coffee meeting. I don't know, I'll finish this. Anyway, it went bust.
And they were married for 13 years. And for the last 7, they've been trying to divorce. And the problem is they don't agree on the settlement.
And so this week, this Tuesday, they've gone to trial and it's proving to be a popcorn-eating worthy affair.
Because it's been open to the public, and some allegations have been a little bit surprising.
And the accusation is basically tried to dump the company for a pittance and a tax dodge and a divorce shrinking of the settlement.
So, we're talking, no one's going hungry here, right? On any side. But it's been rough waters for quite a while now.
Even at the beginning, apparently, when he planned to divorce, he did it by text. So, it's probably safe to say this was not a conscious uncoupling.
She's ghosting me or whatever. Clearly she doesn't want to be with me. She's not returning my calls, she's not returning my texts, etc.
So it happened for a couple of weeks and I thought, oh, clearly I've been dumped. You know, it would have been nice to have known, but clearly I've been dumped.
And so I thought, just to be all upfront about things, sent her a text basically saying it's over, right? Fair enough, you know, look after yourself, etc.
And then she got really, really arsey. And she got arsey because she said, well, there was no way, how dare you dump me via text.
It's like, I've been trying to communicate with you for weeks, you know.
And maybe this tech mogul guy was in a similar scenario.
I don't understand.
So ipso facto, Smashing Security worthy, right?
Maybe his meditation teacher quit. He came to the decision it'd be a good idea to create and make a website live, cleverly entitled AllisonHoon.com, his wife's full name.
You have a list of a number of articles that she's written, but kind of a random selection. And then you have some lawsuits. Oh, yes.
And apparently these connected over to a Google Drive where you could find all kinds of information on these lawsuits, what was going on. And these are from her past.
And they're not necessarily— they're involving sexual harassment and all kinds of ugly stuff. Now, this is the problem. He did a good job of hiding his fingerprints, right?
His fingerprints were all over this. And she had no idea this was live. So this went out in February, and Hoon only discovered it on August 5th.
I knew you would do that, Graham, because you can't believe that people don't Google their names every day, can you?
So it would pop this up at the top of the results or something.
So if anyone was looking for information on her, maybe because she was looking for a job or if she was starting a new relationship, they would end up on this page and they'd think, oh, this looks—
Because the kids are being ultra loud downstairs.
So what's happened is I've hung up a shirt in the cupboard I'm in and it's fallen down, hit my tea, and now I'm standing in a pool of tea. So it's going well.
The material and information contained on this website is for general information purposes only.
You should not rely upon the material and information on the website as a basis for making any business, legal, or any other decisions. Now on with the dirt. I added that last bit.
Lawyer called in the forensic pros, who apparently failed to find anything. But Hoon, no idiot, did.
I was able to determine that the Google Drive site which contained all the lawsuit documents, was registered by Scott Wendell— Scott's middle name.
And to add salt to the wound, she's quoted saying, so the genius of Silicon Valley was exposed by his wife using her technical knowledge. Poetic justice. So it sounds bitter.
It does sound bitter, doesn't it? I think this is much cleverer than you imagine.
Because there's all these reports of him, once the divorce started, or once they separated, he stopped showing up at the office on time. He missed meetings.
Missed meetings all the time. He was basically just, you know, running it to the ground is the argument.
It came together in a moment of frustration when I felt Alison and her attorney were telling one-sided stories to the press. This is the robotics god, apparently.
I thought aggregating publicly available information without commenting or editorializing would help.
It only ended making our dispute more public and tense, which was never what I intended.

My friends over at Attivo Networks have tackled this challenge, and I want to share how it works.
The Attivo Identity Visibility Bundle finds exposed admin credentials from the endpoint.
Conducts over 200 continuous checks on Active Directory and identifies risky entitlement and over-provisioning in cloud environments.
The Attivo Identity Detection Bundle cloaks production credentials and AD objects to hide and deny access and deceives tools like Bloodhound, steering the attacker into decoys for threat intelligence gathering.
If you want to learn more and kick credential attacks to the curb, go to attivonetworks.com. That's Attivo, A-T-T-I-V-O, networks.com.
And thanks to Attivo Networks for sponsoring the show.
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.
And that got me thinking quite a lot about the TV crime genre and having plowed my way through quite a lot of Columbo, I thought, what else did I used to like?
And I'm gonna give you another one right now, which some people may not have seen. It is, of course, Cracker.
Columbo's brilliant, but Cracker is somewhat different. Cracker— I mean, both are brilliant in their own way, but they're very different.
Cracker has a great cast, including Ricky Tomlinson, Geraldine Somerville, Robert Carlyle, Christopher Eccleston, who has one of the most truly memorable moments in TV drama history.
I'm not going to give you any spoilers. OMG. What happens at the beginning of Series 2 of Cracker? Unbelievable.
There was a US remake of Cracker called Fitz, which I've never seen. I imagine is terrible. So go and check out the original Cracker. It is quite brilliant.
And that is my pick of the week.
The thing that I've been obsessing over lately is I've got a wildlife camera, one of these ones that you stick in the corner of your garden and then it's got a sensor, a load of lasers or whatever.
And then whenever an animal that's big enough goes past it or near it, it turns on. And I've managed to get this little fox that we've got that comes and visits our garden.
You can tell how exciting my life is, by the way. But the thing I've been really trying to get is this rat.
There's a rat living somewhere in our garden which we haven't managed to capture. I've seen it once at 6 in the morning, came down for a cup of tea.
There it was sitting on the patio, just chilling out. But I still haven't got it.
And it's a sort of cat and mouse or rat and mouse, if you like, game between me and this creature, which is driving me mad. I've caught— I've got the back of it.
So in one footage, one little video I've got for about half a second, you just see the back of this thing running across the camera. But that is the thing that I'm obsessed with.
And if you've got a garden, and if you've got— I think it was £50 or £60 or something— I strongly recommend these because they are quite good fun, especially with kids as well.
My little boys will wake up in the morning, we'll go and see what the camera got overnight. They'll normally be quite— oh, that's gorgeous. I'll be more excited than they are.
But yeah, we've got a hedgehog, we've got a fox, and we have got the back of a rat.
Flips you the V's, something like that, on the camera.
You see, this all came about because my wife said, can you do something about the rat? I think she meant, can you put a rat trap out?
I don't think she meant, can you get some footage of it on a wildlife camera? So there's been a bit of a disagreement in the household, but I think ultimately that's what she wants.
But I think if we can name it and if we can see it, then we can be friends with it. It can be our pet.
I do not want him living in our garden because we have a walled garden as well, right? I don't want him to go, this is perfect.
We've got bird food, we've got this watering bag, everything we need. This is awesome, right? And come on, honey, come on, right?
And then having thousands of babies everywhere because they just nest and they nest.
I got a big plant pot which is left over from previous nonsense, and I was bored in February in height of lockdown, and I thought, right, I'm going to bury this in the garden, fill it with water, and I've suddenly got a lovely wildlife pond.
It hasn't worked that way. Some of the stuff that grows in there, it's what you'd see in Prometheus. It's horrendous.
Have you ever seen a, what's it called now, a long-tailed rat larvae? Oh, look at— oh, the way they swim, they are otherworldly and terrifying.
Make it an NFT, exactly, just do a couple of conferences a year, and that's me done.
It's a BBC full-cast detective series set in Budapest, 1964. So, 8 years after the Hungarian uprising, when people revolted against Soviet rule.
The country is still at this time, 1964, it's still fraught with political intensity, paranoia about who's listening in on who, because any dissidence is, you know, it's pretty risky.
So in Keeping the Wolf Out, we follow a special investigator, so similar to your Cracker, but a younger guy called Bertalan Lazar and his spy wife, Renzsiska.
And boy, they face a lot of turbulent times. And they try to find out the truth and unmask the true baddies as part of their jobs.
But it's not always easy because a lot of people higher up are up to no good.
But the gorgeous thing is they come together at night and they commune and share over dinner and the relationship between them is just phenomenal. It just oozes with character.
They're sassy, funny, sexy, vulnerable. It's just great. You'd love it, Graham. Joe, I can tell you'd love it. If you were going, "Cracker sounds good," this is just— and it's audio.
And it's actually, you know, I'm not just saying this because I work for the BBC, because BBC's got problems, but what a stroke of genius. I use that app.
All my family and friends use the app every day. It is really good. And you're right, I think they've invested massively in audio.
They've seen the podcasts and dramas like the one you're talking about are massive. And I think, yeah, I mean, it's paying off.
Obviously there's always going to be the hashtag defund the BBC. That will always be there, and they may win one day. Hopefully not.
But yeah, it's really nice to see when they do something like that.
So it's called Keeping the Wolf Out and by Philip Palmer, and it's awesome. Brilliant. Great. That sounds good.
What's the best way for people to that?
