New Antino Backdoor Targets Asian Government Entities

🛡️ Cisco Talos attributes a recent espionage campaign to a China-nexus actor tracked as UAT-11587 that has targeted government and policy organizations across Asia using a previously undocumented Rust-compiled Windows backdoor called Antino. The actor employs tailored spear-phishing lures, sender spoofing, and a multi-stage chain that culminates in DLL sideloading to deploy the implant, which uses Microsoft 365 (Outlook and OneDrive) as its native C2 channel. Talos sees overlaps with known China-aligned clusters but treats UAT-11587 as a distinct activity set.
