.X3 Files Virus (Scarab) – Overview

As announced by security researchers .X3 files virus is a strain of the infamous

Scarab ransomware. It is a kind of malware that invades computer systems in an attempt to reach valuable data, encrypt it and extort a ransom from its victims. In case that you are a victim of .X3 files virus you won’t be able to open encoded files until their code is reverted back to its original state.

When first started on your device, the payload of .X3 cryptovirus initiates the establishment of additional malicious files as the threat will need them for completing successfully sequent attack stages. There are several common folders used by ransomware like Scarab .X3 for the storage of malicious files:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

By executing these files in a predefined order, .X3 performs various malicious modifications that affect essential system settings. Eventually, it becomes able to evade detection and gain persistence on the infected host. How the ransomware gains persistence is by placing malicious values under certain registry keys. Affected registry keys could be Run and RunOnce as they trigger the automatic execution of all files and objects they store information about. So in order to remove completely .X3 cryptovirus and prevent it from loading on each system start, you should ensure that your registries are clean from malicious entries associated with the threat.

Another purpose of infecting registry keys or the key RunOnce, in particular, is the automatic display of a ransom note file called HOW TO RECOVER ENCRYPTED FILES.TXT

Here is what the message in this file reads:

All your files are encrypted!
Your ID


Get a decoder:


The letter should contain the “Decoder” theme (if you do not specify, you can get into spam).
You must send:
1) Your personal identifier
2) Several text files or pictures.
(To test the decoder).
3) the total file size should not exceed 10 MB.

If you try to recover the files yourself,
you will damage them and we will not be able to help you.

By dropping this file on your system .X3 ransomware attempts to urge you into contacting cyber criminals for a decryption tool. To obtain this tool you are forced to pay a ransom fee in cryptocurrency. Beware of the fact that many victims of ransomware never receive an efficient solution even when they choose to pay the ransom. So it is recommendable to avoid ransom payment while waiting for the release of a free decryption tool. Meanwhile, you could attempt to potentially restore .X3 files by using the help of alternative data recovery methods.

.X3 Files Virus – Encryption Process

To complete the main stage of its infection, .X3 files virus activates an in-built encryption module. This module contains a sophisticated cipher algorithm that is able to transform the original code of targeted files.

Like previous variants of Scarab ransomware variant, .X3 is likely to corrupt types of files that store valuable data including:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

Following encryption, corrupted files remain inaccessible and renamed with the extension .X3
