Rever Ransomware

Ransomware attacks have been on the rise these past few years and new ransomware often emerges. This July, it was the case with the Rever ransomware that has some important characteristics.

The main target of Rever ransomware is Synology NAS and Windows Server systems. After breaking in, most often done via unprotected RDP or malicious emails, the attackers encrypt the files defined as important.

The .rever extension is then added to the original name of the files present on the Synology NAS. On the other hand, files from Windows Server environments are given a random .<RANDOM{8}> extension, making it impossible to open files such as OpenOffice, MS Office, database, VM backup, VHD files, and others.

Among the recorded attacks, the most commonly hit locations during intrusions are the \Desktop, \User_folders, and the \%TEMP% folder, which includes the login ID.

The attackers also use the Rever ransomware to generate a text file called “README_recovery.txt”, which is the equivalent of a ransom note. Victims can find the step-by-step necessary to contact the evildoers via the TOX CHAT instant messaging software and pay the ransom in Bitcoin.

In many cases, the group offers a free sample, decrypting a file as proof that they can do file restoration. But this is not a guarantee that the group will do the restoration after payment.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.

Ransomware is designed to be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

Yes, it is possible. You can restart the computer in safe mode which will limit the ransomware’s action as system resources will be locked. You can also disconnect the computer from the Internet which can interrupt the hackers’ connection to your system, it is worth remembering that there is ransomware that works even without being connected to the Internet. You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses have this function.
But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and even the hackers could not restore the files, even with the decryption key. In these cases only a data recovery company, such as Digital Recovery, can recover the files.
