One wallet links $1.55 million FetchAI theft to massive 408.5 million NTX mint
A coordinated Sept. 19 attack used a compromised SingularityNET bridge authorization key to drain 8.72 million FET, worth about $1.55 million. The attacker exploited a withdrawal path with no effective transaction cap and a signature that did not bind the recipient. Twenty-nine minutes later, a dormant compromised NuNet minter created 408.5 million NTX and sent it to the same wallet. Investigators found preparatory transfers and NTX sales before the FET drain, linking the activity. The attacker swapped much of the FET and sold over 217 million NTX; depleted liquidity limited later NTX sales. Fetch.ai paused AGIX-to-FET conversions and its Ethereum-side bridge while investigating, while saying its own contracts and regular FET transfers remained operational. Bitvavo also restricted WMTX activity, but available evidence does not establish that WMTX was compromised through the same method. The report said the affected credentials had not yet been revoked several hours after the attack.
