Hacker Drains $2M From Fetch.ai and NuNet

A single attacker stole close to $2 million from two AI-focused crypto projects, Fetch.ai and NuNet, in coordinated attacks on Sept. 19, according to security firms Blockaid and PeckShield.

The attacker first drained about 8.7 million FET tokens, valued at roughly $1.53 million, from a token converter contract tied to Fetch.ai. The same actor then targeted NuNet, taking additional assets and bringing the combined loss to nearly $2 million.

The incident adds to a growing list of security failures affecting crypto protocols that rely on complex contract permissions and cross-project infrastructure. Token converter contracts, in particular, can create concentrated risk if access controls, upgrade paths or approval logic are not tightly managed.

For Fetch.ai and NuNet, the immediate concern is not only the direct loss but also the operational and reputational damage that follows a public exploit. Even when the underlying protocol remains functional, security breaches can pressure token performance, reduce user confidence and trigger short-term liquidity stress.

The attack also lands at a time when broader market sentiment remains risk-on. The Fear & Greed Index stands at 71, indicating greed, which can amplify reactions to both positive and negative headlines. In that environment, security incidents often produce sharper intraday moves as traders reassess protocol risk.

Neither firm has publicly detailed a full postmortem in the available report, and the exact method used in the attack was not immediately clear. Still, the pattern suggests a single operator or coordinated wallet set exploited weaknesses across multiple contracts rather than a broad ecosystem failure.

Investors should watch whether the affected projects freeze contracts, offer compensation plans or publish forensic findings. Those steps will help determine whether the breach was isolated or indicative of a wider exposure in AI-linked crypto infrastructure.
