Woofun AI data shows that crypto projects incurred approximately $972 million in losses from 207 hacker attacks during the first half of 2026. While the attack count reached an all-time high, total losses remained under $1 billion and were less than half of those recorded in the first half of 2025.

Immunefi reports that DeFi attack losses fell 74% from the $2.62 billion peak in 2022 to roughly $680.3 million, with median single losses declining by 75%. Risk sources are shifting from smart contract vulnerabilities to infrastructure failures, private key leaks, cross-chain configuration errors, and privileged access weaknesses.
