China-Linked APT Expands Arsenal With New ‘Leash’ Backdoors

By Ionut Arghire

AI Summary

Cisco Talos attributed the LapDogs ORB network campaign to Chinese APT UAT-7810, documenting three new custom backdoors — LongLeash, DogLeash, and JarLeash — used to compromise internet-facing SOHO routers. The expanded toolkit signals a deliberate effort to build resilient relay infrastructure for sustained espionage operations. Network security teams should cross-reference Talos IOCs against edge device logs, particularly for routers lacking automated firmware update mechanisms.
