Violent attacks targeting cryptocurrency holders, often referred to as 'wrench attacks,' are on pace for a record year, with over $30 million stolen in the first half of 2026, according to Chainalysis. These attacks, which involve threats or physical violence to force victims into transferring cryptocurrency, have seen a surge in recent years as criminals recognize the wealth held by crypto holders.
Chainalysis documented 46 such attacks through late June, noting that while kidnappings remain common, home invasions have increased significantly, now accounting for 37% of incidents compared to 26% in 2023. Attackers are also increasingly targeting relatives and acquaintances to coerce victims into transferring funds. The firm highlighted that home invasions offer a controlled environment for compelling transfers, whereas kidnappings are more logistically challenging and expose attackers for longer periods.
France has emerged as a focal point for these attacks, with 30 incidents recorded by mid-2026, more than any other country. This rise is reportedly linked to a data breach exposing information on high-net-worth crypto holders, including alleged misuse of French tax records and a breach at crypto tax-reporting company Waltio. The methods used by attackers to launder stolen funds vary, from direct transfers to centralized exchanges by less sophisticated criminals, to the use of decentralized exchanges, bridges, and DeFi tools by more advanced actors seeking to avoid compliance programs.
Previous reports indicate a growing trend, with CertiK noting a 75% increase in wrench attacks in 2025, reaching a record 72 incidents. French authorities have been actively investigating, charging 88 suspects in April. In a separate development, five men were convicted in London for imprisoning and torturing two French crypto millionaires in an extortion scheme.
