Crypto Hacks Hit $630M In April as DeFi Dominates Losses
April saw crypto hacks reach $630M, with DeFi protocols accounting for the majority of losses due to sophisticated exploits.Summary
Cryptocurrency hacks in April surged to $629.7 million, marking the highest monthly losses since February 2025. Decentralized finance (DeFi) was the most targeted sector, with major incidents like KelpDAO's $293 million and Drift Protocol's $280 million exploits comprising 82% of the total losses. These large-scale attacks highlight how a few significant exploits can overshadow broader security improvements. The primary causes of these hacks are increasingly linked to bridges, privileged access, and operational failures, rather than solely smart contract bugs. Chainalysis notes a shift towards sophisticated, multi-stage attacks targeting off-chain infrastructure, such as compromised RPC nodes and cloud key management systems, rather than on-chain smart contract vulnerabilities. Despite these challenges, analysts suggest DeFi's growing resilience and the implementation of solutions to reduce vulnerabilities indicate continued growth for the sector.
