> **Open Intelligence Dossier** · First detected: 2026-07-17 15:07 UTC · Category: Technology

## Executive Summary
Russian hackers are deploying the Starland RAT via trojanized versions of common business tools like Zoom and WebEx to target firms in the US and Europe.

## Intelligence Brief
A new cyber campaign attributed to Russian hackers is targeting businesses across the United States and Europe. According to coverage from BleepingComputer and Security Affairs, the attackers are using trojanized installers for popular business communication software, specifically Zoom and WebEx. These fake applications are designed to deploy the Starland Remote Access Trojan (RAT) onto victim systems. The operation is being linked to a specific threat actor identified as UAT-11795, who is utilizing these trojanized tools to gain unauthorized access to corporate environments. Detailed technical analysis provided by the Cisco Talos Blog emphasizes that this activity is part of a financially motivated campaign. Along with the Starland RAT, the threat actor is deploying a bespoke C2 implant known as WLDR.


The Cisco Talos Blog and Intelligent CISO report that the campaign involves the use of novel malware variants. IT Pro notes that Cisco has officially sounded an alarm regarding these threats, highlighting the risk to firms in both the US and Europe that rely on standard remote collaboration software for their daily operations. This trend matters because it weaponizes the inherent trust users place in essential business software. By masquerading as legitimate installers for Zoom and WebEx, the hackers can bypass traditional user scrutiny. The involvement of UAT-11795 and the deployment of the Starland RAT indicate a sophisticated approach to financial gain through corporate infiltration. The use of a bespoke C2 implant further suggests a tailored infrastructure designed to maintain persistence and control over the compromised networks of the affected organizations.


Looking forward, the focus remains on the spread of the Starland RAT and the activity of UAT-11795. Organizations in the US and Europe must monitor for the presence of the WLDR C2 implant. According to the reported findings from Cisco and other security researchers, the primary vector of infection is the installation of fraudulent software updates or apps. Future updates from security outlets like BleepingComputer and the Cisco Talos Blog will likely track whether new trojanized applications are introduced into this specific financially motivated campaign.
