Huo Xing Finance reports, according to on-chain analyst PeckShield, the cryptocurrency sector experienced 20 major hacking incidents in March 2026, resulting in total losses of $52 million—a 96% month-over-month increase from $26.5 million in February. The most significant risk this month lies in the “shadow contagion” effect, where a single incident triggers cascading bad debts across multiple protocols. Major incidents include: ResolvLabs ($USR) suffered an “infinite minting” attack due to an AWS KMS key management vulnerability, resulting in approximately $25 million in losses; the price of USR plummeted 80%, triggering systemic bad debts across protocols including MorphoBlue, Euler, and Fluid; Venus ($THE) was targeted by a combined on-chain and off-chain attack, leaving $2.18 million in bad debts; prominent on-chain figure @sillytuna suffered a physical and on-chain coordinated attack, losing $24 million; and a Kraken whale user (0xC551...acA21) lost $18 million due to a social engineering attack, with the hacker having transferred part of the funds via Thorchain to HitBTC.
