One wallet links $1.55 million FetchAI theft to massive 408.5 million NTX mint

A coordinated attack drained 8.7 million FET and used a compromised NuNet minter key to create 408.5 million NTX.The Sept. 19 attack emptied the Ethereum-side conversion contract used by SingularityNET’s bridge, removing 8,721,530 FET worth about $1.55 million at the time. Twenty-nine minutes later, a stolen NuNet minter created 408.5 million NTX and sent the tokens to the same receiving wallet, according to an on-chain forensic report prepared by Athena.Fetch.ai subsequently paused AGIX-to-FET conversions and its Ethereum-side bridge contract as a precaution. The company said the affected infrastructure belonged to SingularityNET, primarily its Ethereum-Cardano bridge, while Fetch.ai’s own contracts and normal FET transfers remained operational.The forensic report identified the affected contract as TokenConversionManagerV3, the legitimate Ethereum-side lock-and-release component of SingularityNET’s bridge. Its verified source matches SingularityNET’s public repository, and the contract is tied to the current Artificial Superintelligence Alliance FET token.Investigators traced the loss to a compromised backend authorization key, not a flaw that let an attacker bypass the bridge co...
