Attention Web3 security professionals. A critical intelligence report highlights espionage intrusions attributed to the China-nexus threat actor UAT-7290. Active since at least 2022, UAT-7290 primarily targets telecommunication entities in South Asia and Southeastern Europe, employing extensive technical reconnaissance before deploying malware families such as RushDrop.
The implications for the Web3 ecosystem are significant. UAT-7290 utilizes Linux malware and is reported to exploit “ORB Nodes” during its intrusion campaigns. Since most critical Web3 infrastructure—including validators, node operators, and oracle services—runs on Linux environments, this activity raises serious concerns. The methods used to compromise telecom infrastructure could easily be repurposed or scaled up to target decentralized finance (DeFi) platforms or core blockchain infrastructure operators.
The compromise of underlying communication infrastructure directly threatens the reliability of Web3 services, potentially leading to transaction delays or large-scale data breaches. We urge Web3 enterprises and node operators to prioritize the hardening of their Linux environments, focusing aggressively on patch management and monitoring for unusual network activity, particularly C2 communications potentially leveraging ORB Nodes. Preparedness against state-nexus threat actors must be elevated immediately.
