A surge in crypto-related kidnappings, known as wrench attacks, has placed France under international scrutiny, prompting government officials to address the issue. This year, the country has experienced at least 41 such incidents, averaging one every two to three days.
In response, a new set of measures is being developed to tackle the problem, including a prevention platform that has already garnered thousands of registrations. The global trend also indicates a rise in wrench attacks, with 72 verified incidents in 2025, marking 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 breaking encryption.
Researchers note a shift in attackers' strategies, from targeting wallets to hunting individuals, by building profiles based on social media activity, public appearances, and leaked data. This shift has led to an increase in attacks on mid-level crypto holders, with cases involving families and children, making the severity of these attacks harder to categorize. Notable cases include the kidnapping of Ledger co-founder David Balland and his partner, as well as instances of prolonged captivity and torture.
Experts believe that both opportunistic and organized groups are involved, with signs of increasing coordination among attackers. After obtaining funds, attackers quickly move the crypto assets, converting them into stablecoins and routing them across multiple chains, making recovery more challenging.
The rise in asset prices has increased the potential payoff from a single attack, while improvements in digital security have reduced the effectiveness of purely technical exploits. Underreporting of wrench attacks is also a concern, as many are recorded as standard robberies or home invasions without mentioning the crypto element. To mitigate these risks, security experts recommend measures such as multi-signature setups, withdrawal delays, and spending limits to reduce the incentive for attackers.
