A report released by blockchain security firm PeckShield states that 20 major security incidents occurred in the crypto industry in March 2026, resulting in a total loss of $52 million, a 96% increase compared to $26.5 million in February. However, the report points out that a greater risk lies in "shadow contagion," a chain reaction of systemic risks triggered by attacks. Specifically: 1. Resolv Labs' stablecoin USR experienced a de-pegging incident, with 80 million USR being "unlimitedly issued," causing approximately $25 million in losses and further triggering systemic bad debts in protocols such as Morpho Blue, Euler, and Fluid. 2. Venus suffered a complex attack combining on-chain and off-chain elements, resulting in approximately $2.18 million in bad debt losses. The report also points out that security threats are expanding from on-chain to real-world and social engineering levels. For example, user Sillytuna suffered a combined offline and on-chain attack, resulting in a loss of $24 million; another Kraken big player lost $18 million due to a targeted social engineering attack.
