The number of hacker attacks hit an all-time high, with crypto projects losing approximately $972 million in the first half of 2026.

Odaily Odaily reports that an Immunefi report shows that in the first half of 2026, crypto projects suffered cumulative losses of approximately $972 million from 207 hacker attacks. The number of attacks reached a record high, but total losses remained under $1 billion and were less than half the scale of losses in the first half of 2025. The report notes that DeFi attack losses have dropped by 74% from their peak of $2.62 billion in 2022, falling to approximately $680.3 million, with the median single-loss amount declining by 75% over the same period. Furthermore, the source of risk is shifting from purely smart contract vulnerabilities towards infrastructure failures, private key leaks, cross-chain configuration errors, and weaknesses in privileged access.
