The decentralized Web3 ecosystem fundamentally relies on the robustness of underlying internet infrastructure. Recent intelligence highlights that UAT-7290, a China-nexus threat actor, has been conducting concentrated, espionage-focused intrusions targeting telecommunication entities in South Asia and Southeastern Europe since at least 2022. This group initiates attacks with extensive technical reconnaissance before deploying malware families like RushDrop.
A critical point for the Web3 security community is UAT-7290’s use of Linux-based malware and “ORB nodes.” A vast majority of Web3 infrastructure—including blockchain nodes, validators, and decentralized exchange servers—operates on Linux. If telecommunication infrastructure is compromised, the risk of it being leveraged as a platform for supply chain attacks against Web3 service providers and node operators increases exponentially.
Infiltration into telecom infrastructure provides avenues for potential Denial of Service (DoS) attacks against Web3 services, interception of sensitive communication, and broader system control via malicious firmware updates. UAT-7290’s activities demonstrate a clear intent by state-level actors to bypass Web3’s Layer 3 security and establish dominance starting from Layer 0/1 (the physical infrastructure and OS layers). Web3 projects must urgently re-evaluate their fundamental infrastructure security and monitoring protocols, looking beyond immediate on-chain threats.
