This cryptovirus allegedly encrypts user data and then requires ransom payment to return the files.

The file name: client

Developer: Sorin.

Fake Copyright: Microsoft 2017.

Widia cannot encrypt your files, most probably it is still in development mode. No extension is added to so-called “encrypted” files.

Widia ransomware was first spotted in the second half of May 2017. It is aimed at English-speaking users, which does not prevent it from spreading around the world.

The ransom note is presented on the lock screen. It still can be closed with a combination of keys: Alt + F4. In the upper left corner, there is an inscription in Romanian: De la Sorin pt voi. (Translated: “From Sorin to you”).

Ransom note content:
