Fetch.AI, NuNet and SingularityNET targeted in $17M token attack
Summary
An attacker targeted the infrastructure linked to Fetch.ai, NuNet, and SingularityNET, draining or minting a total of 2.3 billion tokens across five assets, resulting in unrealized profits of $17 million, according to PeckShield. The attack exploited vulnerabilities in backend signing keys shared among these interconnected projects within the Artificial Superintelligence Alliance. Following the incident, Fetch.ai and SingularityNET worked together to deactivate the compromised wallets and contracts, although three of the five affected signing keys had not yet been replaced at the time of the report.

Analysis
NuNet: NuNet is a decentralized computing network project focused on AI and distributed infrastructure, linked to the SingularityNET ecosystem. It maintains its own token minting mechanisms for the NTX token. The project was targeted in the attack through a compromised minting key that allowed unauthorized creation of hundreds of millions of NTX tokens. Fetch.ai: Fetch.ai is an AI-focused blockchain project building decentralized infrastructure for autonomous agents and machine learning applications. It operates within the Artificial Superintelligence Alliance ecosystem alongside related protocols. In the recent incident, its Ethereum-based conversion contract was drained of FET tokens via a compromised signing key tied to interconnected SingularityNET bridge infrastructure. SingularityNET: SingularityNET is a decentralized marketplace for AI services and a core part of the Artificial Superintelligence Alliance. It manages cross-chain bridge infrastructure between networks like Ethereum and Cardano. The project's bridge signing keys were compromised, enabling the attacker to mint large volumes of AGIX and related tokens across multiple assets. Incident Response: Fetch.ai and SingularityNET collaborated to deactivate compromised wallets and contracts following the detection of unauthorized key usage. Alliance Ecosystem: Fetch.ai, NuNet, and SingularityNET operate as interconnected projects within the Artificial Superintelligence Alliance, sharing bridge and authorization infrastructure. Infrastructure Vulnerability: The attack exploited backend signing keys for cross-chain conversion and minting functions shared across the projects' linked systems.
