A disturbing trend is emerging in France, where crypto-related kidnappings, known as "wrench attacks," are becoming increasingly frequent and violent. This shift was evident during a recent international blockchain and crypto conference in Paris, where security was heightened and VIP guests were escorted by police motorcades. The French government has expressed concern over the scale of the problem, with at least 41 reported cases of crypto-related kidnappings and home invasions this year, equivalent to one every two to three days. Minister Delegate to the Interior Ministry, Jean-Didier Berger, announced that new measures are being implemented to tackle the issue, including a prevention platform that has already seen thousands of registrations.

However, authorities acknowledge that further steps are necessary as incidents continue to rise. The term "wrench attack" refers to the use of physical force to extract access to digital assets, which can be an easier option for attackers than attempting to break encryption. According to security researchers and law enforcement data, the trend is not limited to France, with a 75% increase in verified physical coercion incidents globally in 2025.

Attackers are identifying victims by building profiles, tracking social media activity, public appearances, and leaked datasets, and exploiting points of weakness. The problem is exacerbated when attackers receive insider information from government officials. The pool of potential victims has expanded, with mid-level holders being targeted, and cases now include families with children being targeted alongside crypto-holding parents.

Experts warn that anybody can be a potential victim and that the biggest avoidable mistake is tying real-world identity, location, and routine too closely to visible crypto wealth. To reduce the risk, security experts recommend measures such as multi-signature setups, withdrawal delays, and spending limits. As crypto adoption grows, attacks are becoming more frequent and severe, turning a once niche concern into a broader security risk.
