Overview
- Chainalysis reported Thursday that violent physical attacks known as 'wrench' crimes produced more than $30 million in confirmed stolen transfers in the first half of 2026 and about $107 million when failed ransoms and blocked transfers are included.
- Independent tracker CertiK recorded a larger toll, documenting 52 verified wrench attacks and $124.1 million in total financial exposure for H1 2026, illustrating wide differences in how firms count incidents and losses.
- The assault mix shifted this year toward more home invasions, which accounted for about 37% of documented cases, while kidnappings remained common and attackers increasingly targeted relatives to force transfers.
- Chainalysis found three tiers of post‑theft behavior: unsophisticated actors who send funds to centralized exchanges, mid‑level criminals using decentralized exchanges, bridges and MEV tools, and criminally embedded groups that use OTC laundering services.
- French authorities have led a stepped-up response with roughly 200 arrests, 88 indictments and dozens held in pretrial custody, and investigators and exchanges are using on‑chain tracing and freezes while urging holders to limit public exposure and strengthen physical custody.
