Crypto Holders Lose $30M as Wrench Attacks Surge Worldwide

Evolving Tactics

Not every attempt succeeds. Chainalysis reported that only 26% of violent theft attempts through late June resulted in a payout, down from 49% in 2025 and 67% in 2024. The report’s researchers linked the falling success rate directly to France, writing that the country’s attacks are “more numerous, more indiscriminate” and less often successful than the targeted attacks common in prior years.

The nature of the attacks is also changing worldwide. Home invasions made up 37% of documented incidents in 2026, up from 26% in 2023. Kidnappings grew too, from 39% of cases in 2023 to 52% now. Attackers have also started going after family members and associates instead of the crypto holder directly. Chainalysis found that tactic showed up in roughly a quarter to a third of cases globally, and in more than 40% of cases in France alone.

Once an attack succeeds, the stolen crypto has to move somewhere. Chainalysis tracked the money and found three tiers of criminal sophistication. Some attackers send stolen funds straight to a centralized exchange, a mistake that makes them easy for investigators to trace and catch. Others use decentralized exchange (DEX) platforms and cross-chain bridges to cover their tracks. A third group appears embedded in organized crime, with funds flowing through laundering networks tied to drug trafficking and terrorist financing.

French authorities are treating the wave as organized crime. The country’s specialized anti-organized-crime unit, known as JUNALCO, has made around 200 arrests and filed 88 indictments tied to crypto-related attacks, with 75 suspects held in pretrial detention.

Chainalysis explained that the risk mostly falls on local residents rather than tourists. In France, 93% of victims with known residency were locals, a pattern researchers said points to careful planning by attackers, whether through leaked data, social media, or blockchain tracking.

For crypto holders, the report’s advice is straightforward. Avoid publicizing large holdings, keep custody arrangements private, and treat any data breach involving personal information as a security risk, not just a privacy one.

The second half of 2026 will show whether France’s crackdown slows the pace. Chainalysis’s year-end totals will confirm whether 2026 becomes the worst year on record for violent crypto crime.
