.XWZ File Virus – More Information
The name of this ransomware is a derivative of the specific file extension it appends to corrupted files. Analyses of .XWZ crypto virus’ samples conducted by security researchers indicate that the threat belongs to the Xorist ransomware family. The good news is that some of the previous Xorist variants including .C0rp0r@c@0Xr@, .HELLO, and .Files-Frozen- have been successfully decrypted by malware analysts. So the released free decryption tools are supposedly able to decrypt corrupted .XWZ files as well. In the guide below you will find a link to a page that provides some of the available Xorist ransomware decryption tools.
The infection process begins when .XWZ crypto virus is activated on a target system. First, the ransomware should get all malicious files it needs for the attack. For the purpose, its code may be designed to create some of the files directly on the system while others may need to be downloaded from its command and control server. The malicious files are likely to be located in some essential Windows system folders like:
- %AppData%
- %Roaming%
- %Temp%
- %Common%
- %{User’s Profile}%
Afterward, .XWZ ransomware virus initiates a sequence of system modifications some of which are made to ensure its persistence on the infected host. Most of the threats similar to the latest Xorist iteration enter Windows Registry Editor to add malicious values under some sub-keys with paramount functionalities. Such sub-keys are often Run and RunOnce as they manage the execution process of all files that support the regular system performance. Thus, by entering values under these two keys .XWZ ransomware starts automatically on each Windows system launch.
The functionalities of the same keys are likely to be used at the end of the attack when .XWZ crypto virus needs to display its ransom note on PC screen and informs victims the following:
All your files is encrypted using an unknown algorithm!
Do not try decrypt manualy!
You can destroy your files!!
