What is njRat?

The njRat program is categorized as a Remote Access Trojan (RAT). It usually installs without victims' knowledge, stealthily runs in the background (also without victims' knowledge), and collects various sensitive data. Cyber criminals use a number of methods to trick people into downloading and installing programs of this type.

njRat malware

Cyber criminals use the njRat trojan-type program to gather system information, steal various usernames and passwords, and other personal, sensitive details. Additionally, it can be used to download and install malicious software. Generally, these programs send all collected data to remote servers that are controlled by cyber criminals. Stolen/recorded data might be used for blackmail purposes or to generate revenue in other ways. By having access to various personal accounts, cyber criminals can cause privacy problems or even financial loss for the victims. If used to download malicious programs, njRat might download ransomware-type viruses that are often used to block access to files stored on computers unless ransoms are paid. If there is any reason to believe that njRat is installed on your system, remove it immediately, otherwise, it can lead to various problems with data/financial loss and additional computer infections.

njRat is similar to other tools of this type such as ExileRat, Nymeria, Remcos, NanoCore, and RMS. They might be distributed by different cyber criminals, however, the consequences of having these programs installed are serious problems. If installed, njRat runs a process in Task Manager (screenshot below) called "t1uT3wb0.exe". Suspicious processes running in Task Manager are usually malicious programs.

How did njRat infiltrate my computer?

Cyber criminals often distribute malicious programs through emails (spam campaigns) that contain attached files. These are usually MS Office documents, JavaScript files, PDF documents, JavaScript or executable files, archives such as ZIP, RAR, and so on. Once opened, they download and install a specific computer infection. They are also proliferated using dubious software download sources such as Peer-to-Peer networks, unofficial websites, third party downloaders, and so on. Malware might be disguised as a harmless program, however, once downloaded and opened (executed), it causes installation of  viruses. Furthermore, software 'cracking' tools and fake software updaters can be used to proliferate computer infections. Tools that are used to activate paid software free of charge often download and install malicious programs. Unofficial updaters often exploit bugs/flaws of installed software that is out of date. Trojans also distribute viruses - once installed, these programs proliferate other computer infections.

How to avoid installation of malware?

If an email is received from an unknown or suspicious address, do not open attached files or included website links. Software should not be downloaded from unofficial websites, using third party downloaders, Peer-to-Peer networks, or other similar sources. The safest way to download is using official websites and direct links. The same applies to software updates: installed programs should be updated using implemented functions or tools provided by official software developers (not third party tools/fake updaters). Software 'cracking' tools are illegal and often cause computer infections. Therefore, they should never be trusted or used. To prevent computer infections, have a reputable anti-spyware or anti-virus suite installed and keep it enabled. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
