Report: Crypto Hacks Rose 96% in March as Losses Hit $52M
March's $52 million in losses was bad enough, but April has opened with a single incident that resulted in the theft of $285 million.
In March 2026, the cryptocurrency industry experienced a significant surge in hacks, with losses reaching an astonishing $52 million. According to a report by blockchain security firm Peckshield, this marked a 96% increase in the number of major crypto exploits compared to the previous month. The situation has only worsened in April, with a single incident resulting in the theft of $285 million. This alarming trend is not only causing direct financial losses but also triggering a phenomenon known as "shadow contagion," which destabilizes the broader DeFi ecosystem.
Peckshield identified 20 separate crypto exploits in March 2026, resulting in collective losses of $52 million. This figure is nearly double the $26.5 million reported stolen in February. The firm's analysis reveals that these attacks are no longer isolated incidents. Instead, they are creating a ripple effect that destabilizes lending markets, drains liquidity pools, and creates bad debt for protocols that were not directly compromised. This "shadow contagion" has become a growing concern in the industry, as the effects of one breach can ripple through multiple platforms, causing unintended consequences.
One of the largest security incidents in March involved a hack on ResolvLabs, where attackers exploited a vulnerability in its AWS key management system. This allowed them to mint 80 million USR tokens, leading to direct losses of around $25 million. However, the impact extended far beyond ResolvLabs. The breach triggered bad debt across several other protocols, including Morphoblue, Euler, and Fluid. This illustrates how a single exploit can have cascading effects on the entire ecosystem.
Another notable incident occurred on the Thena (THE) market within the Venus Protocol. A hacker bypassed the supply cap, inflated a collateral position to more than three times the intended limit, and borrowed nearly $15 million in assets. While initial reports suggested a $3.7 million exploit, on-chain investigations revealed that the attacker ended up losing over $4 million while creating $2.18 million in bad debt. This highlights the complex interplay between exploits and the broader DeFi landscape, where even seemingly isolated incidents can have far-reaching consequences.
In addition to these large-scale exploits, the report also highlights attacks on individuals. One such case involved a $24 million heist of crypto belonging to online personality Sillytuna. This demonstrates that the threat is not limited to protocols and platforms but also extends to private individuals, further underscoring the need for robust security measures.
The rise in crypto hacks and the resulting shadow contagion are causing significant concern within the industry. As the number of exploits continues to increase, the potential for widespread instability and financial losses grows. The DeFi ecosystem must adapt and strengthen its defenses to mitigate these risks and protect both users and protocols from the cascading effects of these attacks. The rapid evolution of cryptocurrency technology and the growing complexity of DeFi platforms present both opportunities and challenges, necessitating a heightened focus on security and resilience in the face of these evolving threats.
