BlackBerry Prevents: njRAT Malware

njRAT, also known as Bladabindi, is a remote access Trojan (RAT) which was first discovered in 2012. This tool was developed by a threat actor group known as Sparclyheason and used in attacks targeting organizations in Middle Eastern countries. The backdoor has been widely available since its source code was leaked in May 2013. The RAT is popular with both experienced threat actors and amateurs alike.

Most commonly, njRAT is delivered through weaponized documents as part of phishing campaigns. It can also be found masquerading as legitimate or cracked software on file-sharing websites, or delivered through drive-by downloads.

Once deployed to a victim’s machine, njRAT can perform surveillance or even take control of the infected system. The malware’s capabilities include logging keystrokes, capturing screenshots, password stealing, exfiltrating data, accessing web cameras and microphones, and downloading additional files.

The BlackBerry Research & Intelligence Team has analyzed the attack methods used by this threat, and in addition to recommending basic cyber hygiene steps, strongly urges BlackBerry customers to ensure their systems have the following BlackBerry® Cyber Suite components enabled with a blocking policy to detect threats that trigger the specific rules noted below. 

BlackBerry Cyber Suite and BlackBerry Guard stop these attacks.
