Threat Metric

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

The following fields listed on the Threat Meter containing a specific value, are explained in detail below:

Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.

Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.

Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.

Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.

% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

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.
