77 Bloody Codes: When the '$5 Wrench' Shatters the Privacy Myth of France's Crypto Elite
**Summary**
In the first half of 2026, France recorded 77 violent crimes—including kidnappings, illegal confinement, and extortion—targeting cryptocurrency holders, a 71% increase over the 45 cases in all of 2025. This equates to an attack every 2.3 days, making France a global hotspot for so-called "wrench attacks," where criminals use physical violence to coerce victims into surrendering crypto assets.
High-profile cases include the 2025 kidnapping of Ledger co-founder David Balland, who was shown with a severed finger in a ransom video, and an attempted kidnapping of the family of Paymium's CEO in Paris. Prosecutors note these are not isolated incidents but part of structured criminal networks, sometimes involving minors.
Several factors contribute to France's vulnerability: a large holder base (approx. 7.3 million people), the presence of major crypto firms and executives, a culture of public disclosure among enthusiasts, and potential data leaks. The trend is spreading across Europe, which now accounts for over 40% of such global attacks. Research indicates a correlation between Bitcoin price surges and increased wrench attacks.
In response, French Interior Minister Laurent Nuñez announced a three-pillar action plan focusing on enhanced intelligence sharing, deeper cooperation with the industry association Adan, and improved operational and cross-border coordination. Authorities have made over 200 arrests in the past year.
Security experts warn that digital asset safety now extends to the physical world. They advise holders to use hardware wallets, avoid disclosing holdings on social media, enable multi-factor authentication, and report suspicious activity. The situation underscores the urgent need for the crypto community to shift from a "show-off" culture to one of discretion as physical security becomes paramount.
