Crypto Hacks Losses Hit $52 Million In March

Crypto hacks and exploits totaled $52 million in March, marking a sharp escalation in security breaches across digital asset markets. The spike highlights persistent vulnerabilities in decentralized finance infrastructure and rising risks for capital deployed onchain.

Onchain security firm PeckShield reported 20 major incidents during the month, with losses up 96% from $26.5 million in February. A single exploit at Resolv Labs accounted for over $25 million, after an attacker abused a flaw in the protocol’s USR minting contract to generate roughly 80 million unbacked stablecoins.

What Triggered The Surge In Crypto Exploit Losses?

The Resolv incident extended beyond immediate losses, triggering broader instability across interconnected DeFi systems. PeckShield identified “shadow contagion” effects, where the collapse of USR—down approximately 80%—created systemic bad debt across protocols including Morpho Blue, Euler, and Fluid.

Security incidents are increasingly producing second-order impacts rather than isolated losses. But, compared with February’s $26.5 million in total exploits, March’s near doubling underscores how a single vulnerability can cascade across multiple protocols. Similar patterns followed past events, including the $128 million Balancer exploit in November 2025, which contributed to the shutdown of Balancer Labs.

PeckShield emphasized the structural risks tied to interconnected liquidity.

“The real damage lies in the shadow contagion,” the firm noted, pointing to how exploit-driven depegs can destabilize lending markets and collateral positions beyond the initial breach.

Can DeFi protocols contain systemic fallout as exploits grow more complex and interconnected? With attackers continuing to target contract vulnerabilities and users facing rising physical security threats, the next catalyst will likely come from protocol-level security upgrades or coordinated industry responses to mitigate cascading risk.
