What is NEWRAR ransomware? And how does it implement its attack?

NEWRAR ransomware is a dangerous cyber threat designed to lock targeted data in a computer. It is a new variant of Matrix ransomware and uses both the AES 128 and RSA 2048 cryptography. Once it infects a computer, it drops a malicious file which is the one that starts the attack. The payload file may be placed on one of the system folders. It also connects the computer to a remote C&C server controlled by the attackers.

After establishing the connection to the server, several malicious components of NEWRAR ransomware will be added in the system. The crypto-malware then employs an information gathering module used to obtain information about the user and the system. The gathered data, along with some malicious components are used for the stealth protection module. This module is the one that keeps the crypto-malware from being detected by any security programs in the system.

In addition, NEWRAR ransomware also alters some keys and entries in the Windows Registry in order to run on every system boot making its attack persistent. It then scans the computer for targeted files. At the time of writing, it isn’t yet known what kinds of files it targets. As soon as it finds the files, it encrypts them using AES 128 and RSA 2048 ciphers. Following data encryption, it appends the .NEWRAR extension to each one of the encrypted files and drops a file named “NEWRAR_README.rtf” which contains the ransom note stating:
