A disturbing trend is unfolding in France, where a surge in crypto-related kidnappings has led to heightened security concerns. The country has witnessed at least 41 such incidents this year, equivalent to approximately one every two to three days. This alarming rise has prompted government officials to acknowledge the severity of the issue and pledge to implement new measures to tackle it. The problem is not unique to France, as global data indicates a 75% increase in verified physical coercion incidents in 2025, with a significant spike in cases involving physical assault.
The term 'wrench attack' refers to the use of physical force to gain access to digital assets, often proving easier for attackers than attempting to breach encryption. Crypto transactions, unlike traditional bank transfers, cannot be reversed, making them an attractive target for attackers.
Researchers note that the methods used by attackers have shifted from targeting technical vulnerabilities to building profiles of potential victims, tracking their social media activity, public appearances, and routines to identify weaknesses. The situation is further complicated when attackers receive insider information, such as in the case of a French tax official who sold sensitive data to wrench attackers.
The pool of potential victims has expanded, with mid-level crypto holders increasingly being targeted. The attacks have become more brazen, with cases involving families and children, and have resulted in severe physical harm, including torture and mutilation. Experts warn that anybody can be a potential victim and that the rise in crypto prices has increased the potential payoff for attackers, making it a more attractive crime. The issue of underreporting also poses a challenge, as many incidents are recorded as standard robberies or home invasions without mention of the crypto element.
To mitigate the risk, security experts recommend measures such as multi-signature setups, withdrawal delays, and spending limits to reduce the incentive for attackers. As crypto adoption continues to grow, the frequency and severity of these attacks are likely to increase, turning a once niche concern into a broader security risk.
