Fetch.ai NuNet exploit drains $2M, sends NTX crashing 70% to record low

A single wallet drained roughly $2 million from two different crypto projects within hours of each other, and the fallout has been brutal for one of them. The Fetch.ai NuNet exploit hit both protocols through what appears to be the same attacker, according to security firm Blockaid, sending NuNet’s NTX token crashing to a record low while Fetch.ai’s FET absorbed a smaller but still notable hit.

Key takeaways

• The same attacker is linked to exploits on both Fetch.ai and NuNet, involving roughly $2 million in combined value.
• Blockaid says the attacker used a valid authorization signature to drain about $1.56 million in FET from Fetch.ai’s TokenConversionManagerV3.
• The attacker also minted around $452,000 worth of NuNet’s NTX token using the same wallet.
• NTX crashed more than 70% in 24 hours to an all-time low of $0.000328, while FET fell about 5%.
• September 2026 DeFi losses now exceed $333 million across 18 incidents, per DefiLlama data.

Dual Exploit Targets Fetch.ai and NuNet Protocols

One wallet, two protocols, roughly $2 million gone. That’s the short version of what Blockaid reported on September 20, tying a single exploiter to attacks that hit both Fetch.ai and NuNet almost simultaneously. The security firm identified the attacker’s wallet address as 0x1572…c362 and connected it to activity across both projects’ smart contracts.
