Trojanized Windows 10 Operating System Installers Targeted Ukrainian Government

December 16, 2022
Reading Time: 2 mins read
in Alerts

 

Mandiant uncovered a socially engineered supply chain operation focused on Ukrainian government entities that leveraged trojanized ISO files masquerading as legitimate Windows 10 Operating System installers.

The trojanized ISOs were hosted on Ukrainian- and Russian-language torrent file sharing sites. Upon installation of the compromised software, the malware gathers information on the compromised system and exfiltrates it.

At a subset of victims, additional tools are deployed to enable further intelligence gathering. In some instances, we discovered additional payloads that were likely deployed following initial reconnaissance including the STOWAWAY, BEACON, and SPAREPART backdoors.

  • One trojanized ISO “Win10_21H2_Ukrainian_x64.iso” (MD5: b7a0cd867ae0cbaf0f3f874b26d3f4a4) uses the Ukrainian Language pack and could be downloaded from “https://toloka[.]to/t657016#1873175.” The Toloka site is focused on a Ukrainian audience and the image uses the Ukrainian language (Figure 1).
  • The same ISO was observed being hosted on a Russian torrent tracker (https://rutracker[.]net/forum/viewtopic.php?t=6271208) using the same image.
  • The ISO contained malicious scheduled tasks that were altered and identified on multiple systems at three different Ukrainian organizations beaconing to .onion TOR domains beginning around mid-July 2022.
