Aethir, a decentralized GPU cloud infrastructure for AI, confirmed an attack on its bridge contracts and said it halted the exploit. The platform said Friday it had detected and contained an attack on its Aethir (ATH) bridge contracts that connect Ethereum to other chains.
The team said it promptly disconnected the compromised contracts upon detection and worked with major exchanges to blacklist tracked wallets, limiting losses to under $90,000. The update followed a report from blockchain analytics firm PeckShield, which on Thursday flagged an exploit of Aethir’s cross-chain smart contract, AethirOFTAdapter, and estimated losses at about $400,000. PeckShield said the exploiter bridged stolen funds from BNB Chain to Tron and pointed to several addresses.
Aethir said its main ATH supply on Ethereum remains intact and unaffected. The platform plans to publish a full compensation plan next week, and will share a list of attacker wallets, a detailed post-mortem and a repayment plan on Discord. Aethir added it is working with authorities and exchanges to freeze funds and trace the attackers.
Among partner exchanges that responded, Aethir named Binance, South Korea’s Upbit and Bithumb, and HTX. Web3 cybersecurity firm ZeroShadow provided expert analysis to the investigation.
The incident comes amid a larger wave of DeFi hacks: attackers stole nearly $170 million from dozens of protocols in the first quarter of 2026.
Aethir is a decentralized GPU cloud computing network that aggregates GPU resources across a global network for AI, gaming and enterprise workloads rather than relying on centralized data centers. The platform reported $127.8 million in revenue in 2025 and said its decentralized physical infrastructure network (DePIN) stack counted at least 440,000 GPU containers across 94 countries by year-end. Aethir is backed by investors including Animoca Brands and Hashkey and has raised over $140 million for the ecosystem.
