April DeFi hacks hit record 29 attacks

TLDR

April 2026 set a new record for DeFi hacks, with about 29 attacks stealing over 600 million dollars from protocols on Solana, Ethereum, and other chains.

1. Data aggregators report around 28 to 30 DeFi exploits in April, roughly 29 attacks, with about 630 to 650 million dollars lost, mostly from the Drift and KelpDAO hacks.
2. The main vectors were social engineering, bridge and cross chain infrastructure failures, and privileged key abuse, often attributed to North Korea linked groups and increasingly assisted by AI.
3. DeFi users and builders now face a higher baseline risk, making security practices around bridges, admin keys, audits, insurance, and incident response more critical to monitor.

Deep Dive

1. Record Month By The Numbers

DeFiLlama and multiple security firms report that April 2026 saw roughly 28 to 30 DeFi related exploits, a record incident count and about one successful attack per day, with estimates converging around 29 attacks.

According to DeFiLlama, these incidents stole about 635 million dollars, with two mega hacks doing the heavy lifting: KelpDAOs bridge exploit at roughly 292 to 293 million dollars and Drift Protocols attack near 285 million dollars, together accounting for around 90 percent of losses in some tallies.

Coverage from outlets summarizing this data notes that Aprils incident count nearly doubled previous monthly peaks, and that total value locked in DeFi dropped by over 13 billion dollars within two days of the KelpDAO event as users pulled liquidity from bridges and lending platforms.

2. How Attackers Broke DeFi

The big April losses were not classic single line code bugs, but multi step operational failures. Drifts Solana based perps exchange was reportedly compromised via a long social engineering campaign that infiltrated contributor accounts and abused governance and security council workflows.

KelpDAOs exploit centered on its LayerZero based cross chain bridge. Reports describe a one of one verifier setup and compromised infrastructure that let attackers forge a message to unlock 116,500 rsETH without matching backing on the source chain, then loop those assets through lending platforms.

Analysts and firms like TRM Labs link these marquee hacks to North Korea aligned Lazarus and related units, and note that such actors increasingly use AI for reconnaissance, phishing, and targeting long tail protocols that still hold meaningful TVL.

3. What To Watch Next

Protocols hit in April, especially Drift and KelpDAO, are working through recovery and governance processes, including initiatives like DeFi United to recapitalize rsETH and repair knock on damage in lending markets. Monitoring how quickly and transparently they compensate users will be a key signal.

On the defensive side, you can expect more emphasis on multi verifier bridges, stricter signer policies, timelocks, real time monitoring, and default coverage products that embed insurance into vaults instead of optional add ons. Some regulators and banks already cite Aprils numbers in calls for stronger DeFi risk controls.

For individual users, practical risk checks include favoring protocols with documented audits and bug bounties, clear disclosures about admin and upgrade keys, diversified bridges, and well described incident response plans rather than opaque post mortems.

Conclusion

Aprils record 29 or so DeFi hacks show that the main threat to decentralized finance is concentrated in a few very large, operationally complex failures rather than dozens of tiny bugs.

The combination of state linked actors, AI assisted attack workflows, and still maturing bridge and key management practices created a month where both incident count and headline losses spiked, shaking confidence and draining TVL.

Going forward, the critical question is which protocols and ecosystems respond by tightening governance, infrastructure, and insurance in ways that can restore trust and sustainably attract on chain capital.
