The second quarter of 2026 has become the most exploited quarter in crypto history by the number of incidents, with 83 hacks recorded across the industry. According to data analysed by Unfolded and DefiLlama, losses have reached $755.3 million so far, led by the KelpDAO and Drift Protocol exploits. While total losses remain below previous record highs, the growing frequency of attacks highlights persistent security challenges across decentralised finance and blockchain infrastructure.
