Ransomware
If your files have been encrypted, we accept the challenge of analyzing your case.

Ransomware Sekhmet

The Sekhmet ransomware has been increasing the number of its attacks around the world, the group has similarities to the ransomware controlled by the Maze barracks. But even though there are similarities, it is not part of the barracks.

Sekhmet like the vast majority of ransomware groups uses RaaS (Ransomware a as Service) tactics and double extortion.

These two tactics are extremely dangerous and aggressive, RaaS exponentially increases the capacity of attack numbers and scope of these attacks. Double extortion, on the other hand, relies on locking the company’s system by encryption and extracting sensitive files for the company to use for blackmail.

The Sekhmet ransomware maintains a site for leaking files on the Dark Web, and companies are fined if sensitive customer data is leaked.

The main tactic implemented by Sekhmet to break into systems are spam email campaigns, these emails carry files that contain ransomware that when downloaded evades the system defenses and closes them, and also closes any program that could prevent the complete encryption of the files.

After encryption the system is locked and a document is left with the name “RECOVER-FILES.txt” this document leaves instructions on how the victim can proceed to recover their files.

The group provides decryption of at least three files to demonstrate that they have the real decryption key, and they say that after the ransom is paid they send a report to the victim showing how the break-in was done.

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.
