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

A surge in crypto-related kidnappings has put France at the forefront of a global trend, with wrench attacks becoming increasingly frequent, brazen, and violent. The country has witnessed at least 41 such incidents this year, averaging one every two to three days. Government officials have expressed alarm at the scale of the problem, prompting the introduction of new measures to tackle the issue. A prevention platform has already garnered thousands of registrations, but further action is deemed necessary as incidents continue to rise. The term 'wrench attack' refers to the use of physical force to gain access to digital assets, often proving easier for attackers than breaking encryption. 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 problem is exacerbated when insiders, such as government officials, inadvertently aid attackers by leaking sensitive data. 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 the attacks harder to categorize by severity. Experts warn that anybody can be a potential victim, with both opportunistic and organized groups involved. The trend may be linked to rising asset prices, which increase the potential payoff from a single attack, as well as improvements in digital security that reduce the effectiveness of purely technical exploits. As crypto adoption grows, the frequency and severity of attacks are increasing, transforming what was once a niche concern into a broader security risk. Some security experts recommend measures such as multi-signature setups, withdrawal delays, and spending limits to reduce the risk of self-custody, a core principle of cryptocurrency.
