April crypto hacks hit record $647M

TLDR

April 2026 was one of the worst months on record for crypto security, with losses from hacks clustered around 630650 million dollars.

1. Blockchain security firms report about 647 million dollars lost in April across roughly 2540 exploits, the highest monthly total since early 2025.
2. Two DeFi breaches, KelpDAO and Drift Protocol, accounted for more than 90 percent of losses and were likely tied to North Koreas Lazarus Group.
3. The spike in attacks is shifting risk toward bridges, restaking and operational security, pressuring DeFi TVL and short term sentiment for major assets like Ethereum.

Deep Dive

1. Scale Of The Damage

PeckShield data cited by one report puts April losses at about 647 million dollars, up 1,140 percent from March and spread across 40 major exploits.

DefiLlama based tallies show a similar range, with April hacks totaling more than 625 million dollars over 28 to 30 incidents, making it the most hacked month ever by incident count.

Other aggregations that include phishing and smaller incidents push the figure toward around 651 million dollars. Differences mostly reflect what each tracker includes, but all agree it was an extreme outlier month.

2. Key Exploits And Attack Vectors

The damage was heavily concentrated. KelpDAO lost about 292 to 293 million dollars and Drift Protocol around 285 million dollars, together making up roughly 90 to 95 percent of Aprils losses.

These were not simple smart contract bugs. Reports describe months long social engineering to compromise admin keys and cloud infrastructure at Drift, and a single verifier bridge design at KelpDAO that attackers abused by spoofing cross chain messages.

TRM Labs estimates that North Korea linked hackers drove about 76 percent of global crypto hack losses in early 2026, with KelpDAO and Drift central to that total.

3. Market Impact And What To Watch

The KelpDAO and Drift incidents triggered large outflows from DeFi. One analysis cites more than 14 billion dollars in TVL exiting, especially from bridges and lending protocols.

Derivatives and prediction markets reflected higher fear, with several reports noting lower implied odds for aggressive upside in Bitcoin and Ethereum following the hack wave, even as spot prices held key levels.

Going forward, risk is most acute in cross chain bridges, restaking and protocols with concentrated admin control. For users, practical safeguards include favoring mature venues, checking for multi sig and timelocks, and sizing exposure assuming exploits can freeze or haircut funds.

Conclusion

Aprils roughly 647 million dollars in hack losses show that cryptos biggest security threats now come from sophisticated, targeted operations against bridges and governance, not just code bugs.

For DeFi users, that translates into higher tail risk, larger but concentrated blowups and occasional waves of TVL outflows, making it critical to pay attention to protocol security architecture, not just token rewards.
