French jurisdiction bears the brunt of cryptocurrency exploitation, accounting for nearly three-quarters of global wrenching incidents.

A staggering proportion of wrench attacks, which involve physical violence and intimidation to extort digital assets from cryptocurrency holders and their families, have been concentrated in France, with roughly 70% of all such incidents occurring within the country's borders, as reported by renowned Bitcoin journalist Joe Nakamoto. The frequency of these assaults is alarmingly high, with a total of 41 crypto-related kidnappings having taken place in France since the start of 2026, translating to approximately one attack every 2.5 days.

Nakamoto posits that the surge in wrench attacks can be attributed, in part, to the mandatory collection of know-your-customer (KYC) data, which is often stored on centralized servers that have been compromised in high-profile data breaches, such as the 2020 incident involving Ledger, a prominent hardware wallet provider. This particular breach exposed the personal data, including identities, home addresses, and email addresses, of over 270,000 customers worldwide.

Jameson Lopp, CEO of Casa, a leading cryptocurrency wallet and key management company, has weighed in on the issue, stating that France serves as a cautionary example of how stringent financial regulations can create a surveillance state that ultimately puts Bitcoin holders at risk. The cryptocurrency community is growing increasingly wary of KYC data collection, as the number of physical attacks and kidnappings targeting digital asset holders continues to rise, underscoring the need for enhanced security protocols.

According to Nakamoto, these attacks are often masterminded by foreign-based criminals who recruit young individuals in France to carry out the physical assaults. To mitigate the risk of falling victim to such attacks, users can utilize crypto custody services that offer advanced security features, such as a pre-arranged signal or phrase that alerts the custodial company to potential threats, enabling them to freeze assets and notify law enforcement authorities.

Additionally, Nakamoto recommends maintaining a "decoy" wallet containing a small amount of cryptocurrency, which can be surrendered to attackers in the event of a physical confrontation, as well as keeping a low profile and avoiding public discussions about cryptocurrency holdings. The French authorities have reported the arrest of at least 88 individuals in connection with crypto wrench attacks, according to Vanessa Perrée, the national prosecutor for organized crime.
