Fetch.ai and NuNet Hit by the Same Attacker
Blockaid linked the drain to the same wallet; NuNet took the biggest hit, while FET and NTX reacted to the hack on Ethereum.
Key Takeaways
- An attacker stole about $2 million through Fetch.ai and NuNet combined, with NuNet hit the hardest.
- Blockaid said about $1.56 million in FET and around $452,000 in NTX were taken with one wallet.
- NTX fell to an all-time low and FET also dropped, while September now tops $333 million in reported hacks.
An attacker stole about $2 million (€1.7 million) through Fetch.ai and NuNet combined, with NuNet taking the hardest hit. The NTX token fell to an all-time low on September 20, while FET also moved lower after the incident.
How the Attack Unfolded
Blockaid said on September 20 that an exploiter drained about $1.56 million (€1.4 million) in FET from a Fetch.ai token converter on Ethereum. According to the security firm, a valid signature for a conversion authorizer was used to call the conversionIn function on TokenConversionManagerV3.
That single call released the converter's remaining FET supply. Blockaid linked the attacker's wallet to 0x1572...c362. According to the company, the same wallet also received a large NTX mint from NuNet's deployer account, worth about $452,000 (€394,400).
NTX Falls to a Low
Because of that combination, total losses in the wallet cluster rose to about $2.01 million (€1.8 million). PeckShieldAlert also reported that the attacker had already converted the stolen funds into 546.36 ETH, worth about $1.44 million (€1.3 million) at the time of reporting.
NuNet was hit the hardest. NTX fell today to $0.000328 (€0.0003) and traded around $0.0004 (€0.0003), more than 70% lower than 24 hours earlier. FET dropped about 5% over the same period, although that came alongside a broader sell-off in the crypto market, where total market cap fell 4%.
Why This Matters
The attack shows how vulnerabilities in AI-focused blockchain projects can quickly spill over into token prices and trust in a protocol. For European crypto readers, the key point is that this incident is not happening in isolation: September has already seen several major hacks, including a $3.5 million (€3.1 million) loss at Nostra three days earlier. The shift toward key and governance attacks also shows that attackers are increasingly exploiting authorization and admin layers instead of only smart contracts.
Before this Fetch.ai drain, DefiLlama had already recorded about $331 million (€289 million) in losses across 17 incidents this month. With Fetch.ai and NuNet, September now stands above $333 million (€291 million) in reported damage.
