Hackers stole about $168.6M from 34 DeFi protocols in Q1 2026. The largest hack was a $40M private key compromise of Step Finance in January. Other major exploits included $26.4M stolen from Truebit and a private key attack on Resolv Labs. Attacks tend to rise during bull markets and periods of high liquidity, with threats ranging from organized groups to opportunistic hackers. The cryptocurrency community has faced persistent threats from North Korean-linked hackers, including the recent Drift Protocol exploit. However, crypto-related cybercrime has evolved into more complex, highly organized groups that work in coordination to exploit core infrastructure.
