Crypto Hacks Hit Record $1.1B in First Half of 2025

Ethereum and Solana protocols took the heaviest hits, losing roughly $332 million and $326 million respectively. Attack frequency climbed sharply, from 18 incidents in January to 57 in June. April alone saw $635 million stolen, the report noted.

Privileged key misuse drove roughly $790 million in damages, far outpacing code vulnerabilities. The firm said it verified more high-threshold exploits in this period than across all of 2025, signaling a sharp escalation in attacker scale. Emerging risks include prompt injection attacks targeting AI agents and novel wallet delegation exploits that bypass traditional defenses, Blockaid added.

Some vulnerabilities allow partial fund freezes or recoveries through code mechanisms, though outcomes vary widely across cases. The report did not specify which protocols had recovery options. Attackers appear to be shifting toward operational security failures rather than bug exploits, the firm said. June's 57 incidents were the highest monthly count on record.
