ChainCatcher reports, according to DefiLlama data, the second quarter of 2026 became the most active period on record for cryptocurrency hacks, with a total of 83 independent attacks—the highest number ever recorded. Despite the increased frequency of attacks, total losses for the quarter amounted to approximately $755.3 million, still below the $3.56 billion lost in the fourth quarter of 2020. The attacks on KelpDAO ($293 million) and Drift Protocol ($280 million) accounted for more than three-quarters of the quarter’s total losses. Cross-chain bridges were the largest source of losses, with related attacks resulting in approximately $351 million stolen. Earlier this month, Humanity Protocol lost $36 million; Aztec Connect’s passive smart contract suffered two separate attacks, each costing approximately $2.1 million; and the decentralized exchange Raydium suffered a $1.3 million attack in June.
