Threat Signal Report
Remote Utilities Software Distributed in Ukraine via Fake Evacuation Plan Email
FortiGuard Labs is aware that a copy of Remote Utilities was submitted from Ukraine to VirusTotal on February 28th, 2022. The RMS is a legitimate remote administration tool that allows a user to remotely control another computer. The file name is in Ukrainian and is "Evacuation Plan (approved by the SSU on 28.02.2022 by Order No. 009363677833).exe" in translation to English. The SSU likely stands for the Security Service of Ukraine.
Why is this Significant?
This is significant because given its file name, the country where the file was submitted to VirusTotal and the current situation in Ukraine, the file may have been distributed to Ukrainians.
What does the File Do?
The file silently installs a copy of legitimate Remote Utilities software to the compromised machine. The software allows a remote user to control the compromised machine.
Based on the telemetry FortiGuard Labs collected, there is one IP address in Ukraine that connected to the remote IP that likely belongs to the attacker.
How was the File Distributed to the Targets?
Most likely via links in email.
CERT-UA published a warning today that "the representatives of the Center for Combating Disinformation began to receive requests for information from the mail of the Ukrainian Security Service. Such notifications are fake and are a cyberattack".
The email below is reported have been used in the attack.
Email subject: Evacuation plan from: SBU (Urgent) -28.02.2022 day off: 534161

While the remote files were not available at the time of the investigation, the email and "Evacuation Plan (approved by the SSU on 28.02.2022 by Order No. 009363677833).exe" are likely connected based on the email content and the file name.
Can the File Attributed to a Particular Threat Actor?
It's possible that a threat actor distributed the file to target Ukraine. However, while the Remote Utilities software is silently installed on the compromised machine, it displays an icon in Windows's taskbar. Since most threat actors aim to hide their activities, this is potentially an act of novice attacker who tries to take advantage of the current situation in Ukraine.
