HOW TO USE njRAT
It is estimated that the popularity of the njRAT malware in the Middle East and North Africa is because of a large number of online community providing support in the form of instructions and tutorials for development of the malware.


"Technical support and tutorials on using njRAT are widely available on the Web. Symantec has found numerous video tutorials in the Arabic language containing step-by-step processes for downloading and setting up the malware, including steps such as dynamic DNS naming for C&C servers. This level of support enables attackers in the region to easily to build tools and server components for njRAT." researchers said.

“The malware’s author also appears to hail from the region. njRAT appears to have been written by a Kuwait-based individual who uses the Twitter handle @njq8. The account has been used to provide updates on when new versions of the malware are available to download.” they added.

Symantec has also spotted 487 groups of cyber criminals setting-up attacks using njRAT and these “attacks appear to have different motivations, which can be broadly classed as hacktivism, information theft, and botnet building.”

“One such group is the S.K.Y.P.E/Tagged group, which has C&C servers hosted in Egypt and Algeria. The group’s vector for infection is a screensaver hosted on the file sharing site ge.tt. When victims download the compressed .rar file containing the screensaver, they get an executable containing njRAT.”

Symantec said that nearly 80 percent of the command and control servers worldwide were located in the Middle East region and North Africa, such as Saudi Arabia, Iraq, Tunisia, Egypt, Morocco, Algeria, Palestine and Libya.
