update download, which instead downloaded the njRAT trojan.
In January 2023, outbreaks of Trojan infections were seen in the Middle East. The attackers used .cab files with supposedly political conversation, when opened, they launched a
.vbs script that downloaded malware from the cloud.
Architecture
NjRAT, like many remote access trojans, works on the principle of a reverse
backdoor, that is, it requires open ports on the attacker's computer. After creating the malware (client) and opening it, the attacker's server receives a request from the client side. After a successful connection, the attacker can control the victim's computer by sending commands to the server when the client part processes them.
Detections
Common antivirus tags for NjRAT are as follows:
*W32.Backdoor.Bladabindi
*Backdoor.MSIL.Bladabindi
*Backdoor/Win.NjRat.R512373
The standard version of the Trojan lacks encryption algorithms, which is why it can be easily detected by antivirus. However, an attacker can encrypt it manually, so that it will not be detected by popular antivirus software.
