A disturbing trend is emerging in France, where crypto-related kidnappings, known as 'wrench attacks,' are becoming increasingly common and brutal. The country has witnessed at least 41 such incidents this year, prompting government officials to take action. A recent conference in Paris brought attention to the issue, with Minister Delegate Jean-Didier Berger announcing plans to implement new measures to tackle the problem.
The rise in wrench attacks is not limited to France, with global incidents increasing by 75% in 2025, according to Certik and crypto researcher Jameson Lopp's data. The term 'wrench attack' refers to the use of physical force to gain access to digital assets, often targeting crypto holders who are perceived as easy prey.
Researchers note that attackers are shifting their focus from technical vulnerabilities to identifying potential victims through social media activity, public appearances, and leaked datasets. The problem is exacerbated when insiders, such as government officials, provide sensitive information to attackers. The pool of potential victims has expanded, with mid-level holders and even families being targeted. Cases have involved severe violence, including torture and prolonged captivity.
Experts warn that the risk of self-custody, a core principle of cryptocurrency, is increasing as attacks become more frequent and severe. To mitigate this risk, security experts recommend measures such as multi-signature setups, withdrawal delays, and spending limits to reduce the incentive for attackers.
