This weekly security report covers 5 notable attack incidents between May 25 and May 31, 2026, with combined losses of approximately $16M across BNB Chain, Ethereum, Base, Arbitrum, and Cosmos. Key incidents include the DxSale token locker exploit ($7.3M) involving three missing state updates compounded by a deployer key compromise, the SquidRouterModule exploit ($3.2M) caused by improper input validation in an Axelar Bridge integration that allowed forged cross-chain messages to drain 86 Safe wallets, and the Gravity Bridge signing key compromise ($5.4M). Other incidents involve a compromised deployer key (Stake DAO, $91K) and a vulnerable off-chain bridge backend (Alephium, $300K).

In May 2026, the DeFi ecosystem experienced three major security incidents. Echo Protocol lost ~$76.7M due to an administrator key compromise that enabled unauthorized minting of unbacked eBTC on Monad, StablR suffered ~$12.8M from a multisig governance breach leading to unauthorized stablecoin issuance, and the Verus-Ethereum Bridge incurred ~$11.7M following a type-validation failure that allowed a crafted supplemental export to be misclassified as a valid primary export.

~$104.6M Lost: Verus, RetoSwap & More | BlockSec Weekly

This BlockSec weekly security report covers 5 notable attack incidents identified between May 18 and May 24, 2026, with total estimated losses of approximately $104.6M. Two incidents are analyzed in detail: the highlighted $11.7M Verus-Ethereum Bridge exploit, where a type-validation failure allowed a handcrafted supplemental export output to be misclassified as a valid primary export; and the $2.7M RetoSwap exploit on Monero, where a protocol-level authentication flaw in the P2P trade flow allowed an attacker to hijack the arbitrator role via a forged ACK message. Three additional key compromise incidents (EchoProtocol, Polymarket, StablR) accounted for ~$90.2M.
