The cryptocurrency sector experienced a significant increase in security breaches in March 2026, with 20 major hacks resulting in losses of $52 million, marking a 96% rise from February's $26.5 million. The most notable incident involved ResolvLabs, where an AWS KMS breach led to an 80 million USR 'infinite mint,' causing a $25 million drain and triggering systemic bad debt across platforms like MorphoBlue, Euler, and Fluid. Other significant breaches included Venus, which suffered a $2.18 million loss due to a sophisticated on-chain/off-chain attack. Additionally, a physical and on-chain attack on Sillytuna resulted in a $24 million loss, while a Kraken whale fell victim to targeted social engineering, losing $18 million. These incidents highlight the growing threat of what is being termed the 'Shadow Contagion' in the crypto space.
