3 CVEs Mallory has correlated with this family across public research and vendor advisories. Each row links to the full Mallory page for that vulnerability.
UTA0565 used chained Google Chrome exploits CVE-2026-85046 and CVE-2026-87491 with the Windows local privilege-escalation exploit CVE-2026-85880 on September 3-4, 2026, while the vulnerabilities were still unpatched.
The exploit chain included Windows local privilege-escalation exploit CVE-2026-85880. The exploit logic downloaded chrome_cleanup.exe, removed its Mark of the Web, and launched it through the Windows shell using COM.

The final payload, chrome_cleanup.exe, belongs to a previously undocumented malware family that Volexity tracks as CLEANGULP. It installs as %LOCALAPPDATA%\Microsoft\IME\MicrosoftIME.exe, creates a scheduled task named “MicrosoftIME,” and communicates with thecovnresation[.]com.
12 distinct techniques documented for this family, organized by ATT&CK tactic.
The malware was originally written in C and built using the Microsoft Visual C Compiler, then heavily obfuscated using control flow flattening and indirect calls to hinder analysis.
All network traffic observed by Volexity used HTTP as its communication method. After initialization, the malware performs an initial beacon to register with the C2.
