A new report from Bitcoin journalist Joe Nakamoto reveals that approximately 70% of all crypto wrench attacks — physical assaults or kidnappings targeting digital asset holders — take place in France. The data shows 41 such incidents have occurred in the country so far in 2026, equating to roughly one attack every two and a half days.
KYC data collection under scrutiny
Nakamoto attributes the concentration of attacks to centralized know-your-customer (KYC) data collection, which stores sensitive personal information on servers that have been repeatedly compromised. He specifically points to the 2020 Ledger data breach, which exposed the identities, home addresses, and email addresses of over 270,000 customers worldwide. That leaked data, Nakamoto argues, has enabled criminals to identify and locate crypto holders with precision.

Industry warnings and security advice
Jameson Lopp, CEO of crypto wallet and key management company Casa, described the situation as a warning sign for the broader crypto ecosystem. “France is the canary in the coal mine, demonstrating how financial regulations create a surveillance apparatus that causes direct harm to bitcoin holders,” Lopp said. The attacks are often orchestrated by criminals living abroad, who recruit young individuals in France to carry out the physical assaults.
How crypto holders can protect themselves
Nakamoto recommends several security measures for crypto holders, including using custody services that offer a pre-agreed distress phrase. If a holder is under duress, they can use this phrase to signal the service to freeze assets and alert authorities. He also suggests maintaining a “decoy” wallet with a small amount of funds to satisfy attackers, and advises holders to keep a low profile online and avoid publicly discussing their crypto holdings.

Law enforcement response
Vanessa Perrée, France’s national prosecutor for organized crime, confirmed that at least 88 individuals have been arrested in connection with crypto wrench attacks in the country. The data underscores growing concerns about physical security risks tied to digital asset ownership, particularly in jurisdictions with stringent KYC requirements.
Conclusion
The report highlights a troubling intersection between regulatory data collection and physical crime. As crypto adoption grows, the security of personal information stored by exchanges and wallet providers is becoming a matter of life and safety, not just privacy. The situation in France may serve as a case study for other nations evaluating similar KYC frameworks.
FAQs
Q1: What is a crypto wrench attack?
A crypto wrench attack is a physical assault or kidnapping carried out to force a cryptocurrency holder to transfer their digital assets to the attacker. The term derives from the idea that a wrench can be used to coerce someone into giving up their private keys.
Q2: Why are wrench attacks concentrated in France?
According to the report, the concentration is linked to KYC data stored on centralized servers that have been breached, notably the 2020 Ledger leak. This data gives criminals home addresses and identities of crypto holders, making them easier to target.
Q3: How can crypto holders reduce their risk of physical attack?
Experts recommend using custody services with distress protocols, keeping a decoy wallet with limited funds, avoiding public discussion of crypto holdings, and using privacy-focused security practices to minimize exposure of personal information.
