The Butter Bridge V3.1, part of MAP Protocol and Butter Network, was exploited due to a vulnerability in its retry message verification logic, allowing the minting of fake MAPO tokens. The attacker extracted approximately $180,000. The bridge and related swaps were paused, and a patch is in progress.
Adshares Bridge was exploited on Ethereum, allowing an attacker to mint and dump fake wrapped ADS tokens, draining approximately $628K in ETH and USDC from liquidity pools. The project has offered a bounty for the return of funds.
