What Is Exten Virus?

exten virus

Exten virus (.exten files) is another nasty ransomware infection that is aimed only at your files. This threat may extort you in a variety of ways to get you to pay the criminals behind it hundreds of dollars in the form of BitCoin. The main idea here is for these crooks to use sophisticated encryption to “lock” your files and hold them as hostages until you pay a ransom to get the files to work once again.

Exten Virus – What We Know About It

Extend virus may end up being installed on your computer in the two following ways:

  • If it gets sent to you via e-mail as an attachment.
  • If the virus is downloaded as software from a low reputation site.

In case the infection scenario is e-mail, then this virus may pretend, like it is a document that you have to open, due to utmost importance. Examples we have seen are plane tickers, invoices, or something work-related.

If the infection is done by downloading a file, then this file is likely pretending to be some software, like an installer, portable app, crack fix or patch.

Whatever the infection scenario is, once Exten virus ends up on your computer it will act similar to the newer viruses we have detected. Other similar threats to this ransomware we recently saw are Foo virus, Mifr Ransomware, SUMMON virus and others.

The virus begins its malicious activities on your computer by downloading its modules, or virus files. It may set them in the following Windows directories:

  • %ProgramData%.
  • %Windows%.
  • %System%.
  • %system32%.
  • %Roaming%.
  • %AppData%
  • %LocalLow%.>
  • %Temp%.
  • %Local%

Once this is done, Exten ransomware may run a process in the background of your Windows computer. This process will likely scan for and encrypt the following types of files on your machine.

  • Documents.
  • Music.
  • Video files.
  • Archive file formats.
  • Image files.
  • Virtual drive files.
  • Other often-used file types.

But not only this – the virus may also make sure you cannot recover the files after encrypting them. This is why it may use the vssadmin system command in Windows PowerShell to delete the shadow copies and disable Windows Recovery.

.exten Files

After this ransomware encrypts the files, they cannot be opened in any way. The only way to open the files is if you reverse the encryption, which requires a decryption key. Criminals provide it for hundreds of dollars, but in many scenarios malware, researchers often devise a free decryption software if they crack this virus.

The files carry the .exten suffix and they look like the following:
