Starting point is 00:00:00 The attack happened early, on a Tuesday morning in Paris. It's maybe 8.30 in the morning. People are taking their kids to school or daycare. Businesses are opening up. People are having their coffee. That's our colleague Sam Schechner. A white delivery van pulls up and three men dressed in black masks jump out and grab a 34-year-old woman while she's walking with her husband and her two-year-old toddler. Onlookers captured the attack on video. and her two-year-old toddler. — Hello, folks! — I'm sorry, get up! — I'm sorry!
Starting point is 00:00:47 — Onlookers captured the attack on video. — They pepper spray the family and try to drag her into that truck. And she screams. And the husband throws himself in front of her and grabs onto her for dear life and won't let go. And they are trying to pull her away. You know, she's screaming, help, help, help. And, you know, let go of me. Let go of me, damn it.
Starting point is 00:01:12 It's a bomb! Eventually, more people start coming, and a guy who runs a bike shop right nearby runs out of the building holding a fire extinguisher, and he kind of runs at the attackers. And they just hopped in the back of that white van and sped off while the bike shop owner just sort of threw the fire extinguisher after them,
Starting point is 00:01:35 just barely missing the back of the van as it sped around the corner. The assailants fled the scene, leaving the woman, her bloodied husband, and her toddler behind. Why did this happen? Well, this 34-year-old woman, her father, is the CEO of a company called Panium, which is a cryptocurrency exchange based in France.
Starting point is 00:02:05 And investigators believe that the kidnappers were attempting to kidnap her in order to get him to pay a large ransom in cryptocurrency. Okay, so this was an abduction attempt with the idea of extorting the father. This was an old school abduction extortion with the new school twists that what they wanted to be paid in was crypto.
Starting point is 00:02:27 This trend of using violence in the physical world to access someone's online wealth has a name. It's called a wrench attack. And wrench attacks on people who own millions in crypto have been growing across the globe. Another suspect was arrested in the Bitcoin kidnapping and torture case in Manhattan. Three teens accused of kidnapping and robbing a man
Starting point is 00:02:49 out of millions of dollars in cryptocurrency. It comes after a series of kidnappings in Europe targeting crypto magnates. Welcome to The Journal, our show about money, business, and power. I'm Annie Minow. It's Friday, June 20th. Welcome to The Journal, our show about money, business, and power. I'm Annie Minow. It's Friday, June 20th.

Starting point is 00:04:01 The full term for a wrench attack is a $5 wrench attack, and it stems from a comic strip on XKCD, an online webcomic that often covers science and tech. In this two-panel comic, titled Security, two stick figures are trying to hack into someone's crypto account. The first panel depicts, quote, a crypto nerd's imagination. One of the stick figures says, his laptop's encrypted. Let's build a million dollar cluster to crack it. And the other stick figure says, no good.
Starting point is 00:04:32 It's 4096-bit RSA. And then the first one says, blast. Our evil plan is foiled. The other panel is titled, What Would Actually Happen. One stick figure says to the other, his laptop's encrypted, drug him and hit him with this $5 wrench until he tells us the password. The other one takes the wrench and says, got it.
Starting point is 00:04:54 So it's kind of the brute force approach. Yeah, literally brute force, not the crypto brute force approach, but literal brute force. The crypto thefts that you usually hear about happen online, with hackers who break into exchanges or scammers who fish people through text messages. But there's always been the more straightforward approach — violence. And this year, wrench attacks have been on the rise. That's for a few reasons.
Starting point is 00:05:20 One, crypto is more valuable and more worth stealing than ever before. Prices are way up, especially for Bitcoin, which is currently valued at over $100,000. But another reason is that it's just harder to steal crypto online these days. The crypto rich have gotten savvier about where and how they store their keys, the string of numbers and letters that give someone access to their crypto wallet. Increasingly what crypto enthusiasts do is something called self-custody, which means that you keep it offline, air-gapped, away from the internet. There are devices that help you do this.
Starting point is 00:06:01 The old school way would be to write your key down in a notebook, but you know, the keys are very long. So instead, you usually have a device that you keep the keys offline in your pocket or in a safe somewhere. That might insulate you from an online attack, but it won't help you if, for instance, someone breaks into your home and threatens you with violence if you don't give up your key. Who's being targeted in these attacks? The main through line we see is people who are well known for having a lot of crypto. People like crypto influencers. I've made over a million dollars from crypto. Here's my exact rate.
Starting point is 00:06:39 I made two million dollars in 10 months with Bitcoin. I'm sitting in this bed in the studio apartment, and I just became a millionaire. Talking about your crypto wealth online, being an online influencer, a crypto influencer, is becoming a more dangerous game these days. A French influencer named Kylian Desnos learned just how dangerous a few years ago. Kylian Desnos, who is known online as Twiffer, he was a YouTube and Twitch streamer.
Starting point is 00:07:18 Twiffer was well known for his crypto holdings. In August of 2023, two people kidnapped Desnos' father from his house in France. One of them was dressed as an Amazon delivery driver. They sent Desnos a ransom video, showing his father bound with a gun to his head. Desnos paid the ransom, and his father was freed. And this is because Tuffer was a little bit braggie online about his crypto wealth.
Starting point is 00:07:46 Is that? Well, you know, that certainly seems to be the case. And indeed, Tuffer, you know, said that he sort of blamed himself. You know, he said on X that maybe he should have been more secretive. And after the recent kidnapping attempt in Paris, he wrote again on X that these kidnappings remind him of what happened to his family and that he actually got out of crypto. At least two people were later arrested and faced preliminary charges in the case.
Starting point is 00:08:21 Another group that's been targeted in wrench attacks are crypto entrepreneurs, and executives known to have crypto wealth. And the pool of victims comes from around the world. Last July, an Australian crypto billionaire narrowly escaped abduction in Estonia. In March, a Houston crypto influencer's husband got into a shootout with home invaders demanding her laptop. And just last month, there was a big case in New York City. Police made a second arrest in an alleged cryptocurrency kidnapping scheme in New York City. Two men allegedly tortured an Italian man for weeks in an apartment to try to get it as crypto. And then there was a case earlier this year that shocked the crypto world.
Starting point is 00:09:04 Before it ended, somebody would be missing a finger. That's next. The Chevrolet employee pricing event is on now. Get a big cash purchase discount of up to $11,300 on the 2025 Chevrolet Silverado LDZR2 and Silverado HDZR2. With a factory installed lift kit and Multimatic DSSV dampers on both the Silverado LD and HDZR2, you'll have all the capability you need to leave the asphalt behind. Hurry in! Employee pricing is on for a limited time. Visit your local Chevrolet dealer for details. It happened sometime before sunrise in central France.
Starting point is 00:09:58 David Ballant and his partner were kidnapped brutally at gunpoint. They were separated, put in different vehicles, and driven off. — David Ballant is one of France's crypto elite. He helped found a crypto company called Ledger. Within hours of the abduction, other Ledger co-founders had heard from one of the kidnappers. He wanted a ransom of 10 million euros
Starting point is 00:10:24 to be paid in a cryptocurrency called Tether. And his messages made it clear that he wasn't messing around. Very quickly, they escalated to the point of showing a video of Ballon as his finger was cut off. Oh my gosh. He had his pinky finger severed by one of the assailants. And you know, others showed him in emotional distress what looked like a gun to his head. Bellon's friends, his co-founders, went to the police. And together, they'd embark on a multi-pronged strategy. Part one was to start paying some of the ransom, to buy police time to find Bellon and his
Starting point is 00:11:07 partner. And part two involved trying to get those ransom payments back. They had connections to kind of get directly to Tether and to some of the exchanges that were involved so that they could get the cryptocurrency back as soon as the hostages were freed. The idea was that as soon as Balon and his partner were safe, the co-founders' contacts would pull back the ransom payments and recover the money. And that meant that they basically had to stay on a vigil because they didn't know when they would be freed.
Starting point is 00:11:38 And so you had some of the people on this team to claw back the ransom who were up up 24-7. And, you know, there was always somebody on duty waiting for the call, and they were following in real time as police raided one house. Nope, he's not there. Another house. Nope, he's not there. And then finally... -♪ Police raided a farmhouse in the French countryside,
Starting point is 00:12:01 and they found Ballon. David is freed, and they're almost ready to push the button, basically, and make the call to claw back the crypto. And then it turns out that the partner's not there. They'd have to wait until Balon's partner was found to claw back the ransom. But they didn't wait long. They made another ransom payment, and she was discovered the following day in a van at a road stop
Starting point is 00:12:25 an hour and a half north of the farmhouse where police had found Belong. She was shaken but okay. And so that story had a happy ending. But you know, with the caveat that it was a pretty harrowing experience for both of them. Of course. David was one finger short, and he actually he actually later posted to social media on his profile that it was like the, he wrote like Kidnapping Championship 2025, fingers 9 out of 10.
Starting point is 00:12:53 In total, Balan's friends clawed back most of the 3 million euros in crypto that they'd sent as a ransom. It's interesting that the ability to transfer huge amounts of money instantly with crypto kind of facilitates this kind of crime. It makes it attractive at the same time. In this case, the crypto was able to be clawed back almost just as instantly. Yeah, it is an interesting duality. I think a lot of criminals and people in the world in general think crypto is anonymous,
Starting point is 00:13:24 crypto is, crypto is you know Suited to crime but in fact in a lot of cryptocurrencies every transaction is public and so that actually makes it really a treasure trove of information for investigators and it it does make it a little bit more difficult to Launder that money once it's stolen. Did the attackers get away with it? Are they still at large? Well, when they freed Belong, they arrested a bunch of people and another 25 people were arrested in recent days and many of them were charged as linked to more recent kidnappings and others.
Starting point is 00:14:01 So the question is, are they the organizers or are they just, as they'd say in French, petit-mins, little helpers? And it does seem that most of them are young, some of them are minors, they're recruited online, they don't actually know the entirety of the scheme. They're just hired guns. Yeah, they're hired guns. And unfortunately, it means that the people who are profiting from the crime may still be at large.
Starting point is 00:14:27 A few weeks ago, Moroccan authorities arrested a 24-year-old French man, who they suspect was a ringleader in some of the recent abductions. The theory among investigators in France is that these cases are linked. One of the people who was actually arrested in the Killian Desnos case is suspected to have actually been in contact while in prison with the kidnappers in the Ballant case. Interesting. Okay. Then the question is, is that person, is that guy who himself is pretty young in his 20s,
Starting point is 00:15:04 was he the one who was in charge or is he also a hired hand? Despite these recent arrests, the risk of wrench attacks seems to be growing. That's because people who own crypto are increasingly seeing their personal information leaked online. A few years ago, Ledger, the crypto company
Starting point is 00:15:22 Belong Co-founded, had one of its databases hacked. Information for over 200,000 customers was made public. A person familiar with the Ledger breach said that Belon's home address wasn't included in that information. And earlier this year, Coinbase, a major American crypto exchange, was also hacked. Coinbase basically came out and said that as many as 97,000 customers had had their personal information stolen from them and that included things like their balance snapshots. So you know how much crypto they have how much crypto they have which is basically the target
Starting point is 00:15:56 on your back. Right. Also their addresses in some cases and you know the company said that data had been likely stolen by a bribed contractor or possibly employees who were working customer support. So this is information that says, here's exactly how much crypto these people have, here's how rich they are, here's where to find them. Exactly. In some cases, at least, that's the information that was hacked. Coinbase said it's working with law enforcement to investigate the incident and is taking other measures to harden its defenses. What do these wrench attacks say to
Starting point is 00:16:31 you about kind of the moment we're in with crypto? That's a good question. What do they say to me about the moment we're in with crypto? It shows how crypto is becoming that much more important and mainstream. The value of assets in crypto has grown significantly. It's become a magnet for criminals and yet at the same time more and more people are holding it, which creates a wealth of new targets. It's also a sign that perhaps it's still a somewhat immature ecosystem. One of the things that's most attractive about crypto is that it does not rely on the traditional banking system. And it allows you to basically conduct transactions with people you don't
Starting point is 00:17:16 trust without having to rely on a trusted third party, that you can live your life without the need for some central authority. And the question is, you know, how much that vision of a distributed world coincides with the sort of security that we expect today.
