Local government organizations in the United States targeted by Chinese hackers through a zero-day vulnerability in Trimble Cityworks, as reported by Cisco Talos.
Hackers exploited CVE-2025-0994, a high-severity deserialization bug to gain access and deploy malware loaders like Cobalt Strike beacons and VSHell malware.
Cisco discovered intrusions by a threat actor named UAT-6382 in U.S. local government networks, primarily focusing on utilities management systems.
Trimble has since patched the vulnerability, but the US Cybersecurity and Infrastructure Agency recommends prompt application of patches to prevent future attacks.
