|Last seen||May 19, 2023|
|Algorithm||Salsa20 encryption. If Xatz cannot establish a connection to crooks server before starting the encryption process, it uses the offline key. This key is the same for all victims(!), making it possible to decrypt .xatz files in the future.|
|Ransom||From $490 to $980 (in Bitcoins)|
|Distribution||Third-party downloaders, installers, peer-to-peer networks, RDP exploits, etc.,|

What is Xatz ransomware?
The appearance of the .xatz files on your computer mean that you are attacked by Xatz ransomware. This malware is targeted at your wallet - it encrypts the files and then asks you to pay the ransom to decrypt them. Before the encryption, it makes several changes in your system to disable any security mechanisms and prevent the launch of antivirus programs.
Xatz ransomware uses Salsa20 encryption. This cipher is not the most strong encryption but still cannot be decrypted in familiar ways.
The changes Xatz virus does to the security of your system are pretty heavy. The malware disables the Microsoft Defender and alters some configurations, so you will not launch the installation files of most antivirus tools. It also changes the HOSTS file, leading to an inability to open some of the websites with ransomware removal and file decryption guides.
The Xatz ransomware uses the Salsa20 encryption algorithm. That is not the strongest method, but it still provides an overwhelming amount of possible decryption keys. To brute force the 78-digit number of keys, you need 3.5 unvigintillion years (1*10^65), even if you use the most powerful regular PC. Quantum computers can show a bit better results, but it is still too slow to get your files back while you are alive.
The exact algorithm of encryption is next: malware scans each folder for the files it is able to encrypt. Then, when it finds the target, it makes a copy of your file, removes the original one, encrypts the copy and leaves it instead of the removed original. Such a procedure is done to prevent the situation when you have already opened the file, so ransomware is not able to read it because of the Windows restrictions. To each encrypted copy, the virus adds the specific extension - ".xatz". Then, ransomware creates a _readme.txt file in the folder where the encrypted file is located, and goes to the next folder.
Such an encryption method can be exploited for file recovery. Since the original file is deleted, you may try to recover it using the file recovery tools. The less time is passed - the bigger the chance to get your files back, so hurry up!
Another specific moment that can help you to use the files even after the encryption is the fact that Xatz ransomware encrypts only the first 150KB of each file. Hence, you can try to run a big file, such as video or music, without the encryption. Similar feature also works with other ransomware families - Dharma, Conti and Makop encrypt the same 150KB.
Ransom note: _readme.txt
Ransom note is the same for the whole ransomware family. In fact, it is one of the main signs of to which family the certain ransomware belongs. Here is the typical note for STOP/Djvu family:
Don't worry, you can return all your files!
All your files like pictures, databases, documents and other important are encrypted with strongest encryption and unique key.
The only method of recovering files is to purchase decrypt tool and unique key for you.
This software will decrypt all your encrypted files.
What guarantees you have?
