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

Ransomware Lorenz

The Lorenz Ransomware has been growing, even though it has not been active for a long time, it has already managed to hit twelve different organizations. This shows the power of the group. It is similar to ThunderCrypt, apparently Lorenz used its source code.

The Ransomware works internally on a local network, making it find the accesses of the Windows domain administrators.

After that, it selects the files, and moves them to another remote server, making it impossible for the administrators to access them, thus beginning the encryption of the files.

The ransom charged by the group costs on average US $500,000 to US $700,000.

If the victim does not want to pay the ransom, the group releases the files bit by bit, as well as offering access to the network that was attacked.

Lorenz uses AES encryption, and with the embedded key RSA. Each file will have the specific name ‘.Lorenz.sz40’, thus changing its original name and also its extension.

Each victim receives in their folders the file called ‘HELP_SECURITY_EVENT.html’, which has within it the link to the site, with the ransom information, the amount that must be paid in Bitcoin, and offering a chat for negotiations with the hackers.

The group’s strategies to access computers are through program cracks, game patches, and illegal key activation programs, or even purposeful direct attacks.

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.
