Root-cause analysis not yet published. The incident description below contains all currently available signal — review the attack transaction directly for definitive forensics.
Aethir's cross-chain bridge contracts (primarily AethirOFTAdapter and Ethereum-related bridging contracts) were targeted in an exploit. The attacker attempted to drain funds by exploiting access control or ownership transfer vulnerabilities (e.g., transferOwnership issues), involving chains like BNB Chain. The Aethir team quickly detected the anomaly, promptly disconnected the compromised contracts, and collaborated with major exchanges (Binance, Upbit, Bithumb, etc.) to blacklist attacker wallets, effectively containing further damage. The main ATH token supply on Ethereum remained intact, and other bridges like ETH-ARB on Squid were unaffected. Initial estimates put potential losses around $400,000, but user impact was limited to under $90,000. The project promised a full compensation plan. Attack method (per SlowMist): Contract Vulnerability. Reported loss: $ 90,000.
