Analysis Summary
Remcos or Remote Control and Surveillance, marketed as a legitimate software by a Germany-based firm Breaking Security for remotely managing Windows systems are now widely used in multiple malicious campaigns by threat actors. Remcos RAT is a sophisticated remote access Trojan (RAT) that can be used to fully control and monitor any Windows computer from XP and onwards.
The current campaign utilizes Spam Email techniques wherein threat actors are leveraging what’s new and trending worldwide. The phishing email contains a PDF offering CoronaVirus safety measures but in reality, this PDF includes an executable for a REMCOS RAT dropper that runs together with a VBS file executing the malware. The malware also adds Startup registry key at “HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce” for it to become persistent while the device affected has been restarted
This Backdoor gathers the following information and sends it to its servers:
- Computer Information (OS version, computer name, system type, product name, primary adapter)
- User information (user access, user profile, user name, user domain)
- Processor information (processor revision number, processor level, processor identifier, processor architecture)
Impact
