The Alarming Rise of Crypto-Related Attacks in France and Beyond

A disturbing trend is unfolding in France, where a surge in crypto-related kidnappings has prompted heightened security measures, particularly during a recent international blockchain and crypto conference. The country has become a focal point for these wrench attacks, with at least 41 incidents reported this year, translating to roughly one every two to three days. Minister Delegate to the Interior Ministry, Jean-Didier Berger, announced plans to introduce new measures to tackle the issue, including a prevention platform that has already garnered thousands of registrations. The global rise in wrench attacks is also a concern, with 72 verified physical coercion incidents reported in 2025, 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 bypassing encryption. Crypto researcher Jameson Lopp noted, 'Every time a wrench attack is successful, it tells the world that crypto owners are juicy targets.' Unlike traditional bank transfers, crypto transactions are irreversible, allowing attackers to quickly move funds across wallets and chains once a victim is coerced into authorizing a transfer. Researchers have observed a shift in attackers' strategies, from targeting technical vulnerabilities to building profiles of potential victims based on social media activity, public appearances, and leaked datasets. Phil Ariss of TRM Labs warned, 'The biggest avoidable mistake is tying real-world identity, location, and routine too tightly to visible crypto wealth.' The problem is exacerbated when government officials inadvertently aid attackers, such as 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 attacks by severity. In response, security experts recommend measures like multi-signature setups, withdrawal delays, and spending limits to reduce the risk of self-custody. As crypto adoption grows, the frequency and severity of attacks are increasing, transforming a once niche concern into a broader security risk.
