Fetch.ai Publishes On-Chain Review of ASI:One Exploit; Works With SingularityNET to Disable Compromised Wallets and Contracts

Fetch.ai said it has released an on-chain analysis of the attack on the ASI:One platform, mapping the flow from a compromised signing key through to the attacker's cashout wallet. The company noted the report is preliminary and not the final version. According to the report, the breach stemmed from the theft of the backend signature key used by the SingularityNET cross-chain bridge. The attacker used the key to generate valid signatures and drained the contract's full balance—8,721,530 FET (about $1.55 million)—through the conversionIn function. Fetch.ai added that a NuNet minting key was also compromised, allowing the attacker to mint roughly 408.5 million NTX, or around 42% of total supply. Both attack paths were coordinated and initiated within the same minute. At the time of publication, the attacker was still holding about 547.89 ETH and 230 million NTX in a single wallet. Fetch.ai said it and SingularityNET have deactivated the affected wallets and contracts and will provide further updates as the investigation continues.
