Europe’s cryptocurrency holders are getting robbed at gunpoint. Not online. In person.
Armed gangs have stolen $101 million from crypto owners across the continent, according to blockchain security firm CertiK. The criminals work in small teams—usually three to five people—and they’re not hacking wallets. They’re showing up at people’s homes, sometimes dressed as delivery drivers, and forcing victims to hand over their private keys. It’s called a wrench attack, and it’s becoming a serious problem in major European cities where crypto adoption has grown fast over the past few years.
How the Attacks Work
The method is pretty straightforward. Criminals identify someone who holds a lot of crypto. They figure this out through social media posts, public blockchain transactions, or just word of mouth in crypto communities. Then they plan an ambush.
Often, they pose as delivery personnel or service workers. Someone knocks on the door with a package or claims to be there to fix something. Once inside, the situation changes fast. The attackers use physical threats—sometimes actual violence—to force the victim to unlock their phone or computer and transfer cryptocurrency to wallets controlled by the gang. Within minutes, the assets are gone. And because blockchain transactions can’t be reversed, recovery is basically impossible.
CertiK’s data shows these aren’t random crimes. The gangs do reconnaissance. They pick targets based on estimated holdings, which they assess through social media activity or other public information. Some victims have posted about their crypto investments online, making themselves visible to criminals who monitor these channels specifically looking for high-value targets.
The attacks concentrate in urban areas. Big cities with active crypto communities see more incidents, probably because that’s where the money is. Criminals can operate more anonymously in dense population centers, and they can identify multiple targets in a smaller geographic area, making their operations more efficient.
Why Europe
Europe has seen particularly heavy crypto adoption in recent years, especially in countries like Germany, France, and the Netherlands. That concentration of wealth in digital assets creates opportunity for organized crime. The $101 million figure represents confirmed losses, but the real number might be higher—many victims don’t report these crimes immediately, either out of fear or because they’re uncertain how law enforcement will respond.
The criminal groups behind these attacks are sophisticated. They’re not street thugs making impulsive decisions. CertiK’s analysis found that these teams carefully plan each operation, sometimes watching a target for days or weeks before making a move. They assess security measures, daily routines, and the best time to strike.
What makes wrench attacks particularly dangerous is that no amount of digital security helps. You can have the most secure hardware wallet in the world, use multi-signature setups, store your seed phrase in a bank vault—none of it matters if someone’s holding a weapon and demanding you transfer your coins right now. The physical threat bypasses all the cryptographic protections that make blockchain technology secure in the first place.
Law enforcement across Europe is scrambling to respond. But the criminals adapt quickly. As police develop new tactics to track these gangs, the attackers change their methods. They use encrypted communication, rotate team members, and move between jurisdictions to avoid detection. Some gangs have even started targeting victims in different countries, making coordination between national police forces necessary but difficult.
What Holders Can Do
Security experts are telling crypto holders to keep their mouths shut about their holdings. Don’t post screenshots of your portfolio. Don’t brag about gains at parties or on social media. Don’t make yourself a target.
Some recommend storing private keys in non-digital formats—written on paper, stored in secure locations separate from where you live. Others suggest using decoy wallets with small amounts of crypto, so if you are attacked, you can hand over something without losing everything. But that’s not foolproof either.
The bigger issue is that as crypto becomes more mainstream, these attacks will probably increase. More people holding digital assets means more potential victims. And unlike bank robberies, where the money is in a vault protected by security systems and insurance, cryptocurrency sits in digital wallets that individuals control themselves. That makes holders personally responsible for security in ways that traditional finance doesn’t require.
Authorities continue working to dismantle these criminal networks. Several arrests have been made across Europe in recent months, though officials haven’t released many details about ongoing investigations. The challenge is that these gangs operate across borders, and cryptocurrency’s pseudonymous nature makes tracking stolen funds difficult once they’re moved through mixing services or converted to other assets.
CertiK noted that the three-to-five member team structure appears common across different criminal groups. It’s small enough to operate quietly but large enough to overpower a victim and handle logistics like lookouts and getaway drivers. The delivery driver disguise works because it’s non-threatening and gives a plausible reason to be at someone’s door.
The $101 million loss figure spans multiple incidents over recent months. Some individual attacks have netted criminals hundreds of thousands of dollars in a single robbery. For the gangs, the risk-reward calculation is clear: one successful attack can yield more money than months of other criminal activity, and the chances of getting caught remain relatively low if they’re careful about target selection and execution.
There’s no central database tracking these crimes, which makes the actual scope hard to measure. Different countries report statistics differently, and cross-border coordination remains inconsistent. The $101 million figure comes from CertiK’s analysis of known incidents, but security researchers think the real number is higher.
Frequently Asked Questions
What exactly is a wrench attack in cryptocurrency?
A wrench attack is when criminals use physical force or threats to make cryptocurrency holders give up their private keys or transfer digital assets directly to the attackers’ wallets.
How much money have European crypto holders lost to these attacks?
According to CertiK, wrench attacks in Europe have resulted in $101 million in losses, though the actual figure may be higher due to unreported incidents.
How do criminals select their targets for wrench attacks?
Attackers identify targets through social media posts about crypto holdings, public blockchain activity, or information shared in cryptocurrency communities, then conduct surveillance before striking.
