Ransomware Rook

Rook ransomware is the newest malware listed among the possible attackers that takes advantage of the holiday season to increase their attacks.

The vast majority of ransomware attacks are carried out on weekends and holidays, and criminals take advantage of the fact that businesses are off to execute the system attack more easily.

The emergence of Rook brings this concern of yet another group hunting for companies with flaws in their systems. Like the vast majority of ransomware, Rook uses the tactic of double extortion to pressure victims into payment.

In the ransom note left on the victim’s computer, the group threatens that if contact is not made within three days, the files will start to be leaked, and if contact is made within these three days, the ransom will be halved.

In their note, the group leaves numerous threats if the victim seeks outside help to try to negotiate or decrypt the files.

In order for their intentions to be taken seriously, the group releases the decryption key for up to three files that are no larger than 1MB. The groups need to weaken the mind of the victims so that they see paying the ransom as the only way out to get their files back.

Digital Recovery specializes in recovering encrypted files without the need for a decryption key.

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.

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.
