China-Linked UAT-7810 Expands ORB Network With New LONGLEASH Malware

China-linked threat actor UAT-7810 is making waves with its new LONGLEASH malware, designed to expand its Operational Relay Box (ORB) network by targeting internet-facing networking devices. This advanced persistent threat actor has been maintaining and spreading LapDogs, an ORB network first discovered in 2025. The implications are significant as this expansion could enable more sophisticated cyber espionage and surveillance operations, posing a serious risk to global cybersecurity infrastructure.
