Crypto Hacks Cost $1.18 Billion In Q3 As Smart Contract Exploits Surge
Summary
Hacken reported $1.18 billion in crypto losses across 107 security incidents in Q3 2026, up 55% from Q2. Smart-contract exploits accounted for 48% of losses, compared with 12% the prior quarter, while access-control and operational failures fell from 88% to 40%. The largest individual losses involved supply-chain attacks, compromised keys, and weaknesses in signing and withdrawal systems. Hacken cautioned that contract audits alone cannot protect surrounding infrastructure, deployment processes, or third-party software, and noted that some exploits used weaknesses with publicly available fixes. The report underscores the need for ongoing security checks alongside audits.
