French authorities have charged 88 people in connection with 12 separate crypto wrench attacks across the country. These violent incidents targeted cryptocurrency holders. The charges were announced by the French National Police on April 25, 2026. The attacks occurred between January 2025 and March 2026. They represent a growing threat to digital asset owners.
What are crypto wrench attacks?
A crypto wrench attack is a physical assault. The attacker forces the victim to transfer cryptocurrency. The name comes from the idea that a wrench (or similar tool) can be used to compel someone to hand over digital funds. Unlike digital hacks, these crimes involve direct violence or threats.
According to the French police report, the 12 attacks involved a range of methods. In some cases, attackers broke into homes. In others, they followed victims from crypto meetups. The goal was always the same: access to private keys or exchange accounts.
Data from the French Ministry of the Interior shows a 40% increase in such physical crypto crimes in 2025 compared to 2024. This suggests the problem is getting worse. Industry watchers note that the rise of decentralized finance (DeFi) has made more people targets.

The 88 charged: who are they?
The 88 individuals charged include both men and women. Ages range from 19 to 55. Many had prior criminal records for theft or assault. Some were part of organized crime groups. Others were opportunists who learned about victims through social media.
Police investigations used a mix of surveillance, digital forensics, and witness testimony. Blockchain analysis helped trace stolen funds. In three cases, victims identified attackers from crypto community events. The arrests took place in multiple cities: Paris, Lyon, Marseille, and Nice.
Breakdown of charges
- Armed robbery: 34 people face this charge. It carries a penalty of up to 20 years in prison.
- Kidnapping: 22 people are charged. Victims were held for hours while forced to transfer funds.
- Extortion: 18 people face this charge. Threats of violence were used.
- Conspiracy: 14 people are charged for planning attacks.
The implication is clear: law enforcement is treating these crimes with maximum severity. French prosecutors have requested bail be denied for most defendants.
Why are crypto holders targeted?
Cryptocurrency transactions are irreversible. Once sent, funds cannot be recovered. This makes crypto holders attractive targets. Unlike bank accounts, there is no fraud protection. Private keys are the only barrier.
According to a 2025 report by Chainalysis, physical crypto thefts accounted for $350 million in losses globally. France represented about 12% of that total. The average loss per victim was $29,000. Some victims lost over $1 million.
The attacks often involve a “wrench” or similar tool. But attackers also use knives, guns, and even bare hands. The key element is coercion. Victims are forced to log into their accounts and transfer funds. In some cases, attackers held victims’ families hostage.
Timeline of the 12 attacks
| Date | Location | Loss (USD) | Method |
|---|---|---|---|
| January 2025 | Paris | $150,000 | Home invasion |
| March 2025 | Lyon | $80,000 | Carjacking |
| June 2025 | Marseille | $1.2 million | Kidnapping |
| August 2025 | Nice | $45,000 | Street robbery |
| October 2025 | Paris | $500,000 | Home invasion |
| December 2025 | Lyon | $200,000 | Extortion |
| February 2026 | Marseille | $75,000 | Follow-home |
| March 2026 | Nice | $900,000 | Kidnapping |
This timeline shows the geographic spread. It also reveals that losses vary widely. The implication is that even small holders are at risk.
How French police cracked the case
French police used several techniques. First, they monitored crypto forums and social media. Attackers often boasted about their crimes. Second, they analyzed blockchain transactions. Stolen funds were sometimes moved through mixers. But police traced many to exchanges where attackers cashed out.
Third, they used traditional detective work. Victims described their attackers. In some cases, attackers left fingerprints. One victim recognized a neighbor who had asked about crypto. That lead broke a major case.
According to a police spokesperson, “The collaboration between cybercrime units and local police was essential. We shared data across jurisdictions. This allowed us to connect the dots.” The operation was called “Operation Secure Key.” It lasted 15 months.
What this means for crypto users
The charges send a strong message. But the threat remains. Crypto holders need to take precautions. Here are some recommendations from security experts:
- Don’t publicize holdings: Avoid posting about crypto on social media. Attackers often scout victims online.
- Use multi-signature wallets: This requires multiple keys to authorize a transaction. It can slow down an attacker.
- Keep a decoy wallet: Store a small amount of crypto in a wallet with a small balance. Give that up under duress.
- Use hardware wallets: Keep most funds offline. Only transfer small amounts to hot wallets for daily use.
- Be discreet: Don’t wear crypto-branded clothing or accessories. This marks you as a target.
What this means for investors is that physical security is now part of crypto risk management. The old advice was about digital security. Now, it’s about personal safety too.
Broader implications for France and Europe
France has some of the strictest crypto regulations in Europe. The country requires crypto exchanges to register with the AMF (Autorité des Marchés Financiers). It also enforces KYC (Know Your Customer) rules. But these laws do not prevent physical attacks.
European lawmakers are now discussing new measures. One proposal is to create a database of crypto-related violent crimes. Another is to fund police training on crypto forensics. The European Union’s Anti-Money Laundering Authority (AMLA) is also involved.
Industry watchers note that these attacks could slow crypto adoption. If people fear for their safety, they may avoid holding crypto. This could hurt the broader ecosystem. But the French response shows that law enforcement is adapting.
Conclusion
The charges against 88 people in France mark a significant step in fighting crypto wrench attacks. The 12 incidents highlight a violent trend that targets cryptocurrency holders. French police used a combination of digital forensics and traditional detective work. The arrests send a clear message: these crimes will be prosecuted aggressively. But crypto users must also take personal precautions. The threat is real, and it is growing. As the industry evolves, so must security practices. The French case is a warning for crypto holders everywhere.
