Data compiled by Woofun AI shows that the second quarter of 2026 witnessed a surge in cybersecurity threats, with 83 independent cryptocurrency hacking incidents recorded, marking a new historical high for attack frequency. Despite this escalation in volume, the aggregate financial damage totaled approximately $755.3 million, a figure significantly lower than the $3.56 billion lost during the fourth quarter of 2020.

The majority of these losses were concentrated in two major events: the $293 million breach of KelpDAO and the $280 million exploit of Drift Protocol, which together accounted for more than three-quarters of the quarter's total damages. Cross-chain bridges emerged as the most vulnerable infrastructure category, with related attacks resulting in approximately $351 million in stolen assets. Additional notable incidents included a $36 million loss by Humanity Protocol, two separate attacks on Aztec Connect's passive smart contracts totaling roughly $4.2 million, and a $1.3 million exploit targeting the decentralized exchange Raydium in June.
