A surge in crypto-related kidnappings, known as 'wrench attacks,' has put France at the center of a global rise in violent attacks on crypto holders. The country has experienced at least 41 such incidents this year, prompting concerns from government officials and a push for increased security measures. The trend is not limited to France, with global data showing a 75% increase in verified physical coercion incidents in 2025.
The use of physical force to extract access to digital assets has become a lucrative method for attackers, with crypto transactions being irreversible and allowing for quick movement of funds across wallets and chains. Researchers note that attackers are shifting their approach from targeting technical vulnerabilities to building profiles of potential victims, tracking their social media activity, public appearances, and routines to identify points of weakness. The biggest mistake crypto holders can make is tying their real-world identity, location, and routine too closely to their visible crypto wealth. The problem is exacerbated when attackers receive insider information from government officials, as seen in a case where a French tax official sold sensitive data to wrench attackers.
The pool of potential victims has expanded, with mid-level holders and even families being targeted. Cases have involved prolonged captivity, torture, and severe violence, making it harder to categorize the attacks by severity.
Security experts point to the need for increased coordination and information sharing between authorities to combat the growing threat. They also recommend measures such as multi-signature setups, withdrawal delays, and spending limits to reduce the risk of self-custody and limit the incentive for attackers.
As crypto adoption continues to grow, the frequency and severity of attacks are likely to increase, turning what was once a niche concern into a broader security risk.
