April Was the Worst Ever Month on Record for Crypto Hacks

April 2026 was a record-breaking month for crypto hacks, with 29 incidents resulting in $651 million in losses, raising concerns about blockchain reliability.

April 2026 has earned a dismal reputation in the cryptocurrency community, marking the worst month ever recorded for crypto hacks. With 29 incidents tracked by crypto data provider DefiLlama, the total losses reached a staggering $651 million , the highest monthly total since March 2022, excluding the notable Bybit hack of February 2025. What Does This Mean for Blockchain Reliability? The surge in hacking incidents has sparked concerns among crypto market observers regarding the reliability of blockchain infrastructure, especially for traditional financial institutions. Major figures in finance, including BlackRock’s Larry Fink and JPMorgan Chase’s Jamie Dimon, have previously praised the potential of tokenization. However, the recent DeFi hacks challenge the readiness of this technology for mainstream use. Which Hacks Caused the Most Damage? Among the notable hacks in April, the incidents involving Drift and Kelp DAO stand out, collectively resulting in losses of $579 million . The Drift hack, in particular, has drawn attention due to the six-month social engineering operation conducted by North Korean agents to infiltrate the protocol. This attack exemplifies a growing trend, as a recent report from blockchain analytics firm TRM Labs revealed that 76% of all crypto value extracted from hacks this year has connections to North Korea, with the regime reportedly accumulating over $6 billion from these operations historically. Can DeFi Recover from This Blow? The ramifications of these security breaches extend beyond immediate financial losses. They put into question the institutional appeal of decentralized finance (DeFi). A recent analysis from JPMorgan indicated that “persistent security vulnerabilities” coupled with a stagnant total value locked (TVL) continue to hinder DeFi’s attractiveness to Wall Street firms. Instead of engaging with the inherent risks of decentralized networks like Ethereum, traditional financial institutions may opt for more controlled block
