Odaily News: Bitcoin News posted on X platform that a new technical analysis released by @KLoaec shows that some vulnerable COLDCARD Mk3 wallets may be generated from only approximately 4.5 million random number generator starting states, which can be searched in about 3 seconds on a single RTX 4090 GPU. Even accounting for additional uncertainty in each wallet's generation method, an attacker could complete the search in about 50 minutes on a single high-end GPU. More critically, this vulnerability could cause different devices to generate identical mnemonic phrases. Assuming 30,000 Mk3 devices, the analysis estimates that approximately 120 pairs of devices could generate the same random number stream. This collision estimate is theoretical but indicates that duplicate mnemonic generation across different devices may be possible.
Decentralized GPU cloud computing infrastructure platform Aethir confirmed that its Ethereum-related bridge contract was attacked. The team promptly disconnected the affected contract and, in collaboration with major exchanges, blacklisted the hacker’s wallet, limiting losses to under $90,000. Earlier, blockchain security firm PeckShield estimated losses at $400,000. The attacker exploited Aethir’s cross-chain smart contract, AethirOFTAdapter, to transfer stolen funds from BNB Chain to Tron. Aethir stated that its Ethereum mainnet ATH token supply remains unaffected. It plans to release a detailed compensation plan and incident analysis next week and will collaborate with exchanges including Binance, Upbit, and Bithumb to freeze funds. Web3 security platform ZeroShadow is assisting with the investigation. In 2025, Aethir achieved $127.8 million in revenue and deployed over 440,000 GPU containers globally.
