A crypto wallet is turning into a reason for actual physical violence — not a hack, but a home invasion or a kidnapping. According to a new report from blockchain analytics firm Chainalysis, criminals extracted nearly $30 million from crypto holders through violent attacks in the first half of 2026. Add in the failed attempts — cases where a victim managed to freeze a transfer or a ransom got traced and seized — and the total climbs to $107 million.
The industry has a nickname for this: wrench attacks, a nod to the old webcomic where a $5 wrench beats any cryptographic defense. Chainalysis found that home invasions now make up 37% of incidents, up from 26% back in 2023. Kidnappings are rarer but account for 53% of the money stolen — criminals hold a victim until relatives send the crypto.
France tops the list by a wide margin. One reason, according to Chainalysis: a 2024 data breach in which a French tax official sold information on wealthy crypto holders — names, addresses, holdings, phone numbers. A separate breach at hardware wallet maker Ledger last year leaked buyer contact details too. French authorities logged 77 crypto-related kidnapping and extortion cases in 2026, up from 45 in all of 2025 — a 71% jump. More than 200 people have already been arrested.
Over 40% of the French cases targeted family members rather than the crypto owner directly — it's simply easier to force a payment that way. Local crypto businesses have responded by signing up en masse for emergency identification services; 724 people are now registered.
Chainalysis sorts the attackers into three tiers: lone opportunists who just force a direct transfer, more capable groups that route stolen funds through DeFi protocols and decentralized exchanges to cover their tracks, and organized networks with access to OTC laundering desks. A strong password and a cold wallet won't stop someone standing in your living room — and that's a problem the crypto industry still hasn't figured out how to solve.
