DefiLlama data shows that the second quarter of 2026 has become the most active period for recorded cryptocurrency hacking attacks, with a total of 83 independent attack incidents, setting a historical high. Despite the increase in attack frequency, the total losses for the quarter were approximately $755.3 million, still lower than the $3.56 billion in the fourth quarter of 2020.
Among these, the $293 million attack on KelpDAO and the $280 million attack on Drift Protocol accounted for more than three-quarters of the total losses for the quarter. 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 contracts faced two attacks, each resulting in losses of about $2.1 million, and the decentralized exchange Raydium experienced a $1.3 million attack in June.
