According to official Bisq sources, the protocol was attacked due to a lack of verification mechanism, resulting in the theft of approximately 11 BTC and involving altcoin trading. Attackers exploit the negative miner fee vulnerability to transfer funds through multi signature transactions. Bisq is discussing a compensation plan, and victims can choose to compensate with Bitcoin or BSQ tokens, subject to DAO voting. It is expected to be determined after May 25th. The official has fixed the vulnerability and plans to release patches and strengthen the security review of the code repository. At the same time, it is recommended that users reduce the amount of BTC stored in their wallets. Bisq stated that the event is controllable and hopes to provide safety warnings for other projects.
