The Alarming Rise of Crypto-Related Violence: How France Became a Hotbed for Wrench Attacks

A disturbing trend is emerging in France, where crypto holders are being targeted in increasingly brazen and violent attacks, known as wrench attacks. This phenomenon has prompted government officials to take notice and implement new measures to tackle the issue. According to Jean-Didier Berger, Minister Delegate to the Interior Ministry, at least 41 crypto-related kidnappings and home invasions have occurred in France this year, translating to approximately one incident every two to three days. The country has become the epicenter of a global surge in wrench attacks, with security researchers and law enforcement data indicating a significant rise in such incidents worldwide. In 2025, there were 72 verified cases of physical coercion globally, representing a 75% increase from the previous year. 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 break encryption. Researchers note that attackers are now focusing on identifying vulnerabilities in individuals rather than exploiting technical weaknesses. They build profiles of potential targets by monitoring social media activity, public appearances, and leaked datasets, making it essential for crypto holders to be mindful of their online presence and security. The problem is further complicated when government officials inadvertently aid attackers by leaking sensitive information. 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, highlighting the need for increased awareness and security measures. Experts suggest that both opportunistic and organized groups are involved in these attacks, with some displaying signs of coordination and pre-planning. After obtaining funds, attackers often quickly convert them into stablecoins and transfer them across multiple chains, making recovery more difficult. The rise of wrench attacks in France may be attributed to a combination of factors, including leaked personal data and cross-border criminal networks. As crypto prices increase, the potential payoff from a single attack grows, while improvements in digital security have reduced the effectiveness of purely technical exploits. The issue of underreporting also exists, as many wrench attacks are recorded as standard robberies or home invasions without mentioning the crypto element. This lack of visibility can make it challenging for authorities to connect cases and identify broader patterns. The increase in attacks has raised concerns about the risks associated with self-custody, a fundamental principle of cryptocurrency. Security experts recommend implementing measures such as multi-signature setups, withdrawal delays, and spending limits to reduce the risk of wrench attacks by limiting access to funds under duress.
