The Surge of Violent Crypto Crimes in France

This year, France has witnessed a alarming rise in violent crimes targeting digital asset holders. Official statistics reveal at least 41 recorded cases of kidnapping and home robbery directly linked to cryptocurrencies, averaging one incident every 2.5 days. This trend has prompted significant governmental concern. Jean-Didier Berger, representing the Interior Ministry, stated that a series of new counter-strategies and measures are being developed in collaboration with Interior Minister Laurent Nuñez.

The Global Spread and Evolution of 'Wrench Attacks'

The term 'wrench attack' specifically refers to coercing victims through physical violence or intimidation to transfer their crypto assets. According to security agencies and researchers, globally verified cases of such physical coercion reached 72 in 2025, a staggering 75% year-on-year increase. Cases involving actual physical assault saw an even more dramatic surge, rising 250%. Notably, the attack methodology is evolving: criminals are no longer merely searching for anonymous wallet addresses but are proactively 'hunting' individuals. They utilize social media platforms, data breach information, and other channels to precisely pinpoint the lifestyles and identities of high-value targets. The kidnapping of Ledger co-founder David Balland in France in January 2025 serves as a stark example of this new trend.

The Crime Chain and Security Recommendations

Due to the irreversible nature of cryptocurrency transactions, recovering assets after forced transfers is extremely difficult. After successful attacks, perpetrators often quickly convert illicit gains into stablecoins and utilize cross-chain technology to move funds across different blockchain networks, complicating the trail and evading law enforcement. Faced with this escalating security threat, industry experts propose several defensive measures:

  • Utilize Multisignature Wallets: Require multiple key authorizations to complete transactions, increasing difficulty for a single point of compromise.
  • Implement Withdrawal Delay Mechanisms: Set time locks for significant transactions, providing a potential buffer and alert window during coercion.
  • Apply Spending Limits: Restrict the daily or per-transaction amount for wallets, lowering the ceiling for potential one-time losses.
The combined use of these tools can significantly enhance the security tier of personal digital assets and reduce the risk of becoming a target.
