Introduction:
A sophisticated cyberattack involving a Chinese-speaking threat actor, tracked as UAT-6382, has raised alarms in the cybersecurity community. This actor exploited a critical vulnerability in the Trimble Cityworks software, affecting utility management systems. With the intent to establish long-term access, UAT-6382 used advanced malware like Cobalt Strike and VShell, launching a series of attacks on U.S. local government networks. The breach highlights the increasing threat to critical infrastructure and underscores the importance of timely software patching.

UAT-6382, a Chinese-speaking threat actor, targeted a vulnerability in Trimble Cityworks, a GIS-centric asset management software, to launch cyberattacks on U.S. local government networks. This vulnerability, CVE-2025-0944, was linked to remote code execution, allowing the threat actor to deliver Rust-based and Go-based malware, including Cobalt Strike and VShell. Cisco Talos researchers confirmed that UAT-6382 exploited this flaw to gain unauthorized access to systems, conducting reconnaissance and deploying web shells and custom malware to maintain long-term access.
The exploitation of CVE-2025-0944 was discovered in January 2025 and quickly patched. The vulnerabilityâs high CVSS score of 8.6 made it a prime target for cybercriminals. After gaining access, UAT-6382 demonstrated a specific interest in utility management systems. The attacker used publicly available malware frameworks, such as MaLoader, to build the Rust-based loader, which allowed further exploitation and the deployment of backdoors. Tools like AntSword, chinatso/Chopper, and Behinderâcommonly associated with Chinese hacker groupsâwere deployed to exfiltrate data from compromised systems. Cisco Talos reported that the attackers enumerated directories, identified sensitive files, and executed PowerShell scripts to further compromise the systems.
What Undercode Says:
UAT-6382âs attack strategy is a textbook example of a highly targeted, multi-layered cyberattack aimed at critical infrastructure. This actor was not just exploiting a vulnerability for immediate gains but rather took deliberate steps to establish a foothold in the victim networks for long-term persistence. The choice to target utility management systems is strategic, given their critical role in daily operations. The exploitation of CVE-2025-0944 is significant because it demonstrates how even seemingly niche vulnerabilities in specialized software can open doors for widespread attacks on essential public services.
The exploitation of Trimble Cityworks reflects an increasing trend in cybercriminals targeting the broader public sector. As government entities become more reliant on technology for managing utilities and critical services, they also become more attractive targets. The fact that this attack began in early 2025, with reconnaissance and web shell deployment occurring quickly after the vulnerability was discovered, highlights the speed at which these actors operate. UAT-6382âs use of a combination of sophisticated malware tools like Cobalt Strike and VShell, along with the Rust-based TetraLoader, emphasizes their technical expertise and ability to execute complex cyberattacks.
This type of attack poses a significant challenge for cybersecurity teams. Despite the patch being applied to CVE-2025-0944, the attackers had already established multiple backdoors on the systems, indicating a need for robust defense mechanisms and proactive monitoring in the post-patch phase. The use of widely available malware, including frameworks like MaLoader, makes it even more difficult for defenders to anticipate and prevent such attacks.
Itâs also worth noting that the vulnerability was added to the U.S. Cybersecurity and Infrastructure Security Agencyâs (CISA) Known Exploited Vulnerabilities (KEV) catalog. This inclusion means that security experts are aware of the issue and can prioritize patching. However, the fact that many government bodies were still compromised even after the patch was released points to gaps in vulnerability management and incident response.
In conclusion, UAT-6382âs attack underscores the growing threat posed by well-organized, state-sponsored cybercriminal groups targeting critical infrastructure. Organizations must adopt a multi-layered approach to cybersecurity, including timely patching, continuous monitoring, and advanced threat detection systems, to stay ahead of such persistent and evolving threats.
Fact Checker Results:
The CVE-2025-0944 vulnerability has indeed been patched and added to CISA’s KEV catalog.
The malware tools identifiedâCobalt Strike, VShell, and TetraLoaderâare widely recognized in cybersecurity reports.
The attack occurred in January 2025, targeting U.S. local government networks.
Prediction:
With the increasing sophistication of cyberattacks, especially targeting critical infrastructure like utilities, we can expect more advanced state-sponsored groups to exploit such vulnerabilities. Itâs likely that other similar vulnerabilities in asset management software will be targeted in the near future, making it essential for governments and enterprises to prioritize cybersecurity measures to safeguard public services.
