Crimson Rat Description


The Crimson RAT is a JAVA-based remote access Trojan, which is not paid so that any cybercrooks can use it to craft their threatening server component that can then be distributed by whatever means necessary. Since cybercrooks of all levels can take advantage of the Crimson RAT's features, it is safe to say that this threat can approach you from just about anywhere – spam e-mails, fake social media profiles, fake downloads, pirated software, media, etc. The best way to keep your PC safe from threats like the Crimson RAT is to use a credible anti-malware software suite that will keep an eye on files and network connections to ensure that no unsafe activity is taking place.

If the Crimson RAT is executed on an unprotected computer, then the attackers may gain access to a rich remote control toolkit that gives them the ability to features such as:

  • Spy on the victim's webcam, microphone and desktop.
  • Exfiltrate files and data from the victim's computer.
  • Record keystrokes to acquire login credentials and sensitive information.
  • Execute remote commands.
  • Download additional threats.
  • Lock the users out of their computers.

Since Remote Access Trojans are meant to be silent, their victims may often have no idea that a harmful activity is taking place on their computers. The processes linked to the Crimson RAT don't take up any resources or network data so that users will not notice any noticeable differences. In addition to this, the authors of the Crimson RAT may use various Registry key names, filenames, and process names to ensure that their threat will look as inconspicuous as possible.

Since detecting a RAT manually is impossible for average users virtually, we advise our readers to make sure that their computers are protected by an up-to-date anti-virus software suite sufficiently.
