RemcosRAT is a Threatening Remote Administration Tool (RAT) that may allow attackers to control the victim's computer remotely, exfiltrate data from it, and perform a large number of other actions that may help them gain access to private information, payment details, passwords and valuable files. RemcosRAT is detected by many popular anti-malware software currently so that installing a reliable anti-malware solution is certainly one of the best ways to protect yourself from this threat. While RemcosRAT is active, it can inject its corrupted payload in existing processes silently, therefore masking its presence from the user. If the infection goes unnoticed, then RemcomRAT will allow its operators to perform the following operations on the victim's machine:

  • Upload, download and modify files.
  • Execute commands remotely.
  • Take screenshots from the user's desktop or webcam (if available).
  • Copy clipboard data.
  • Log keystrokes.
  • Launch and terminate processes.
  • Install additional threats.M/li>

RemcosRAT features a large number of modules that may provide attackers with full control over the victim's computer. This threat may often be spread with the help of fake software downloads, fake driver or software updates, bogus e-mail attachments and pirated software.

If you suspect that your computer might be infected with this threat or a similar variant, then you should take the necessary actions to install and run an anti-malware scanner that can resolve the issue in a matter of minutes.
