$GT Gate News reports that on April 1, the blockchain security firm PeckShield released a report stating that by March 2026, the crypto industry experienced a total of 20 major security incidents, with cumulative losses reaching $52 million, a 96% increase compared to $26.5 million in February. The report points out that a greater risk lies in "Shadow Contagion," which is the chain reaction systemic risk triggered by attacks. Specifically: Resolv Labs' stablecoin USR experienced a de-pegging event due to 80 million USR being "infinitely minted," resulting in approximately $25 million in losses and further causing systemic bad debt in protocols like Morpho Blue, Euler, and Fluid; Venus faced a complex attack combining on-chain and off-chain methods, leading to about $2.18 million in bad debt losses. Additionally, the report highlights that security threats are expanding from on-chain to real-world and social engineering layers, with user Sillytuna suffering an attack combining offline and on-chain methods, losing $24 million; another major CEX account was targeted by a targeted social engineering attack, losing $18 million.
