CertiK: Wrench attacks rose 33% in H1 2026, driving $124 million in losses
AI Market Summary
CertiK’s H1 2026 data shows physical "wrench attacks" rising 33% YoY to 52 incidents, with reported losses jumping to about $124.1m, concentrated in Europe (notably France). The surge in crypto-related burglaries highlights escalating off-chain custody risk that cannot be mitigated by on-chain security alone. Near term, this may dampen risk appetite and increase demand for institutional-grade custody and insurance solutions.
