Saba ransomware is the latest variant of the notorious STOP (djvu) ransomware that has been causing havoc for victims worldwide. Like its predecessors, Saba is spread through malicious files disguised as freeware, key generators, and hacked games, which are commonly found on file-sharing and torrent sites. Once installed, Saba encrypts all files on the victim’s computer, adding the “.Saba” extension to the filenames. The attackers then demand a ransom payment in exchange for the decryption key, with the initial ransom demand set at $980, but halved to $490 if paid within 72 hours. In this article, we will take a closer look at Saba ransomware, its distribution methods, and the steps that victims can take to recover their encrypted files.

What is Saba virus/ransomware?
Saba ransomware is a new variant of the STOP (djvu) ransomware that emerged in early 2022. This ransomware is spread by malicious files that must be installed as an .exe by the user. Typically, such malicious files are disguised as freeware, Windows/Office key generators and activators, hacked games, and other attractive downloads that are placed by cybercriminals on file-sharing and torrent sites.
Upon execution, Saba creates a folder in the Windows system directory where it places a copy of itself and changes some Windows settings so that it starts up every time the computer is restarted or turned on. The virus then collects information about the victim’s computer and tries to establish a connection with its command server (C&C). If the connection has been established, it sends information about the infected computer to the server and, in response, receives the encryption key (the so-called ‘online key’) and additional commands and malware that must be executed on the victim’s computer. If the virus cannot establish a connection with its command server, it uses a fixed key (the so-called ‘offline key’).
The Saba ransomware encrypts files using a strong encryption algorithm and a key (‘offline key’ or ‘online key’, as described above). The virus attempts to encrypt as many files as possible, encrypting only the first 154kb of the contents of each file to speed up the encryption process. Saba has the ability to encrypt files on all drives connected to the computer, including internal hard drives, flash USB disks, network storage, and more. It skips files located in the Windows system directories, files with the extension .ini, .bat, .dll, .lnk, .sys, and files with the name ‘_readme.txt’. All other files located on the victim’s computer can be encrypted, including popular file types such as .doc, .docx, .xls, .ppt, .pdf, and others.
Saba encrypts files one by one, renaming each encrypted file with the .Saba extension at the end of its name. Thus, it marks all encrypted files. In every directory where there is at least one encrypted file, the virus places a file named ‘_readme.txt’. The file contains a message from the Saba authors, informing the victim that all their files are encrypted and the only way to decrypt them is to purchase a key and a decryptor from the authors of the Saba ransomware. That is, criminals demand a ransom for unlocking the victim’s files. The ransom demand is typically $980, but if the victim pays within 72 hours, then the ransom amount is halved to $490. The attackers offer victims a way to verify that encrypted files can be decrypted by sending them a small file to one of the email addresses specified in the ‘_readme.txt’ file. However, it is unlikely that paying the ransom will result in the successful decryption of all files, and victims are encouraged to seek alternative solutions.
Security researchers confirm that all files with the extension ‘.Saba’ are encrypted and cannot be read or used without the key and the decryptor. Fortunately, a free decryptor called “STOP Djvu decryptor” is available from Emsisoft that can decrypt encrypted files. Even if the decryptor does not help, there are some alternative ways that can help restore the contents of the encrypted files. To learn more about decrypting files, simply scroll down to section ‘How to decrypt .Saba files’.
In conclusion, Saba ransomware is a dangerous malware that can cause significant damage to a victim’s files and data. It is essential to take measures to protect your computer, such as avoiding downloading suspicious software and installing reputable anti-malware software. If you have been infected with Saba ransomware, it is crucial to act quickly.

Steps to determine the type of key used for file encryption
To decrypt files encrypted by Saba File Decrypt Tool, it is important to know which key was used during encryption. You can find out the type of key used through two methods. Both methods are effective, but the second method is considered to be more accurate and therefore recommended.
Identifying the Type of Key Using the ‘_readme.txt’ File
- Open the ‘_readme.txt’ file, which is the ransom demand message created by the Saba ransomware.
- Scroll down to the end of the file.
- Look for a line of text that says ‘Your personal ID’.
- Below this line, you should see a string of characters. This is your personal ID, which is unique to your computer and is used to generate the decryption key.
Identifying the Type of Key Using the ‘_readme.txt’ File
- Open the C drive on your computer.
- Open the ‘SystemID’ directory.
- Look for the ‘PersonalID.txt’ file and open it./li>
- This file contains a list of ‘Personal IDs’ that match the keys that the ransomware used to encrypt files./li>
The ‘Personal ID’ is not the actual key that was used to encrypt files, but rather an identifier that corresponds to it. If the ID ends with ‘t1’, the files were encrypted with an offline key, whereas if it does not, the Saba virus used an online key. If you are unable to determine which key was used, you can request assistance by submitting a query here or in the comments section.
Saba File Decrypt Tool : “No key for New Variant online ID”
