UAC-0099, a Russia-aligned group, has pushed its MATCHBOIL downloader from Ukrainian transport firms into a manufacturer and an energy company, ESET says. The researchers tracked the tool for almost two years; it installs MATCHWOK, a C# backdoor that grabs screenshots and runs PowerShell.

Invisible HTML elements carry the commands for UAC-0099's ASHVEIN RAT

TrendAI has tied ASHVEIN, a previously undocumented .NET RAT, to UAC-0099 attacks on Ukrainian government personnel, citing five builds from October 2025. The group has fielded newer tools since, so detection that lasts has to target how it delivers and tasks its implants.

Ukraine's cyber agency ties DarkSword iPhone attacks to hacked news and government sites

Ukraine's SSSCIP says Russian hackers are going after military and government phones, using hacked news and government sites to push the DarkSword iPhone kit. Because the kit needs little or no action from the victim, the defense falls on the phone's own software and how current it is.
