UAT-6382
UAT-6382 is a Chinese-speaking threat actor. Reporting cited in the provided content states that UAT-6382 exploited a Trimble Cityworks zero-day, identified in the content as CVE-2025-0994 and also referenced once as CVE-2025-0944, to deliver Cobalt Strike and VSHELL. The actor has used SNOWLIGHT, a generic stager for the VSHELL malware family. Cisco Talos observed that SNOWLIGHT behavior used by another China-nexus cluster, UAT-8302, shared the same single-byte XOR key (0x99) and stager behavior seen in UAT-6382 activity, indicating tooling overlap. The content also notes that SNOWLIGHT has been used by UNC5174 and UNC6586. No additional aliases or sub-groups for UAT-6382 are provided in the content.
