An attacker drained roughly $480K from AFI Protocol's afiUSD vault on Ethereum, swapping DAI to ETH and routing about 150 ETH through Tornado Cash; the root cause was not immediately disclosed.

An attacker submitted forged guardian VAAs to Alephium's Wormhole-fork TokenBridge, draining about $815,000 of custody assets from Ethereum and BNB Chain in roughly seven minutes.

Gravity Bridge, the Cosmos-Ethereum cross-chain bridge, was drained of roughly $5.4 million after attackers apparently compromised validator signing keys and forged unauthorized withdrawals.

Verus-Ethereum bridge paid out $11.58M after an attacker submitted a 0.02 VRSC export — no source/destination value-binding check on either side.

~$10.8M drained from THORChain Asgard vaults across nine chains via a suspected GG20 threshold-signature flaw exploited by a malicious node operator.

Wasabi Protocol's perp vaults across Ethereum, Base, Berachain and Blast lost $5M when a compromised deployer EOA with sole ADMIN_ROLE allowed UUPS upgrades.

$292M unbacked rsETH minted after attackers exploited KelpDAO's 1-of-1 LayerZero DVN setup; the largest DeFi hack of 2026, with TVL falling $13B after.

1B bridged DOT minted on Hyperbridge after a missing bounds check in VerifyProof let an attacker forge MMR proofs; realised loss ~$2.5M.

Resolv Labs lost $25M after attackers compromised its AWS KMS keys; a $100K USDC deposit minted 50M USR and depegged the stablecoin 74% in 17 minutes.

Solv Protocol's BRO vault lost $2.73M when an ERC-3525 double-mint bug let the attacker turn 135 BRO into ~567M BRO over 22 deposits, then swap for 38 SolvBTC.

Truebit lost $26.4M when an integer overflow in TRU's five-year-old bonding-curve contract let the attacker mint TRU near-free and sell back for 8,500 ETH.
