Parisher Ransomware How Is It SpreadParisher Ransomware How Is It Spread

For Parisher ransomware virus to infect the maximum amount of users, the virus may utilize a sophisticated combination of tools and spreading methods. Believed to be a variant of the notorious Mobef ransomware, the Parisher virus is believed to be spread in two primary ways:

Spam e-mail attachments being sent out to users and cause infection upon opening without being detected.
URLs that are posted on social media and aim to cause redirects to malicious drive-by web links once they are opened.

Parisher Ransomware – More Information

As soon as this ransomware virus has infected users’ computer, it could start to create files that are malicious and conceal them via process obfuscators in different Windows folders. The files may be different file types:

→ .exe, .tmp, .dll, .cmd, .bat, .vbs

They may also be existing under different names, most commonly names resembling legitimate Windows programs such as “notepad.exe” or “svchost.exe”. The usually targeted folders for this are:

%AppData%
%Roaming%
%Local%
%SystemDrive%
%UserProfile%

After having infected the user, Parisher may delete all of it’s shadow volume copies that create a file history via the vssadmin command:

After performing this, the Parisher virus may create a custom value string in the “Run” or “RunOnce” registry keys:

HKEY_LOCAL_MACHINE>Software>Microsoft>Windows>CurrentVersion>Run

The objective of those value strings is to begin looking for several different file extensions, primarily associated with programs that are often used.

Once the virus has discovered those file extensions, it will begin to encode files. These files are then enciphered with the sole purpose to no longer be opened. Unlike Mobef Ransomware, on which this virus is most likely based on, the encrypted files by this virus are primarily archives, and they do not have any file extension appended to them.

After encryption, this ransomware drops a note on a file that is named “1NFORMAT1ONFOR.YOU”. The note has the following content:

“ID:7459374
PC:DC01
USER:administrator
=======
Hello there. I can decrypt your files.
Email me: parisher@protonmail.com
In case you don’t get a reply, please email me here*:
parisher@inbox.lv, parisher@mail.bg, parisher@india.com
* check your junk/spam folder first though :-)MM
These files have been encrypted (please, keep this .log): C:\Windows\7459374.log”
