reported losses

live sources

Executive summary

Total known losses exceeded $1.86B, driven by a $1.8B social-engineering fraud (HyperFund) and a $42M social-engineering attack. Additional losses of $14.6M (UXLINK swap), $2.2M (smart-contract bug), and $500K (Immunefi) were reported. Dominant vectors were social-engineering and supply-chain malware, with smart-contract bugs ongoing. Intelligence sources note a broken Immunefi feed, so coverage may be incomplete.

Social-engineering scams remain the highest-value threat by far
Supply-chain malware via Steam wallpaper clipper is active
Multisig keys sharing a single machine introduces private-key risk
Circuit public input binding bugs persist in zero-knowledge protocols
