UAT-9244, a China-nexus advanced persistent threat actor, has been targeting critical telecommunications infrastructure in South America since 2024. The group employs three new malware implants: TernDoor, a Windows-based backdoor variant of CrowDoor; PeerTime, an ELF-based backdoor using BitTorrent protocol; and BruteEntry, a brute force scanner for SSH, Postgres, and Tomcat servers. UAT-9244 uses dynamic-link library side-loading, scheduled tasks, and registry modifications for persistence. The group is closely associated with FamousSparrow and Tropic Trooper, sharing similar tooling and tactics. Their infrastructure includes multiple command and control servers and operational relay boxes for scanning and brute-forcing activities.
