Cross-chain bridge attacks dominated losses, with one exploit accounting for over a third of the quarter’s stolen funds.
Cryptocurrency hacks reached a record $351 million in Q2 2026, driven by a surge in cross-chain bridge exploits. The LayerZero OFT bridge breach, linked to the $293 million KelpDAO hack, alone represented 38% of total losses for the quarter.
Compromised admin attacks and fake token price manipulation contributed 37% of losses, while private key compromises made up 5.66%. Other notable incidents included a $36 million theft from Humanity Protocol and a $10.7 million exploit on THORChain.
Recent attacks, such as the $1.7 million theft from Ethereum layer-2 Taiko, highlight ongoing vulnerabilities in bridge protocols. Smaller exploits, including two on Aztec Connect and one on Raydium, added to the quarter’s losses.
