MATCHBOIL is a custom C# downloader malware used by the Russia-aligned APT group UAC-0099. It downloads and installs payloads from command-and-control servers and establishes persistence on victim machines. The malware has evolved since April 2024, adding obfuscation, sandbox detection, and changing persistence mechanisms. It is distributed via spearphishing emails with malicious links that download VBScript files. MATCHBOIL typically delivers the MATCHWOK backdoor as its final payload. All known victims are Ukrainian organizations in transportation, manufacturing, and energy sectors.
