NJRat Description


NJRat is a Remote Access Trojan (RAT) whose primary purpose is to provide its operator with unsupervised access to the victim's computer. The threat is meant to run on the compromised host silently, and give the remote attacker the ability to spy on their victims, manage their files, and perform a long list of harmful and operations. The malware was first seen in 2013, and it was used in the Middle Eastern region predominantly – however, through the years it was adopted by hundreds of threat actors and used all around the world. One of the biggest surges of NJRat attacks occurred in 2014 when thousands of computers in India were infected by this threatening application.

The NJRat also has served as a foundation for the development of other malware families and various cyber threats:

  • Lime Ransomware – a file-locker that also installed the NJRat on the victim's computer.
  • Njw0rm – an extended NJRat variant that packed additional features, and has the ability to copy its files to USB drives and removable storage connected to the infected host.

Since the server builder and client components of the NJRat have become public, and threat actor can make use of them and opt to reach their targets by using various propagation channels and social engineering tricks. Copies of the NJRat may often be hosted on torrent trackers, posing as software keygens, game cracks or other pirated content. More sophisticated threat actors have been seen spreading copies of the NJRat via corrupted links posted on Discord servers, fake social media profiles/conversations, and bogus email attachments.

Some of the NJRat's core features are:

  • Establish a remote desktop connection to the infected host.
  • Silently browse the victim's files and directories.
  • Access the victim's Web camera or microphone and use them for recordings.
  • Modify the Windows Registry, Task Manager and Windows Services.
  • Launch a keylogger.
  • Collect saved passwords (browser, FTP, messaging applications, etc.).
  • Access websites or download files from the Web.

Protecting your computer from the NJRat and the threat actors who use it can be achieved by following the best safe browsing practices. Never download pirated movies or media, avoid torrent trackers, and do not mess around with software or game cracks. Naturally, only trust files coming from reputable sources and websites, and make sure to double-check the source's credibility – cybercriminals can spoof email addresses or use bogus domains to trick you into trusting the wrong source. Last but not least, make sure to have your system protected by a regularly updated anti-virus software suite.
