Because maker and taker were supposed to use the same miner fee, a malicious taker could push a bad fee value through the transaction math and shrink the multisig output to 0.001 BTC while sweeping the rest into the taker's change. Attacker drained 11.59 BTC from 10 users, all on altcoin trades. Maintainer Henrik Jannsen filed a reimbursement plan on GitHub on May 3, payouts in BTC (with BSQ as optional), DAO vote scheduled around May 25. The hotfix landed as Bisq 1.10.0 on 2026-05-16 with broader hardening: trade protocol checks, network message validation, release verification, supply-chain hardening. The Bisq team explicitly flagged the incident as a likely AI-assisted exploit, though they did not detail how AI was used.Sterlingov Appeal: The Criminalization of Privacy (therage.co)Published: 2026-05-12The appellate court reviewing Roman Sterlingov's Bitcoin Fog conviction openly suggested that mixers remain "legal in theory but not practice" once criminals use them.
