Overview

Names Distribution
Legion virus, Legion ransomware Email, Exploit Kit, Social Media

Legion is predominantly distributed by malicious email messages that contain malicious links and attachments. The email attachments will usually be a .zip file or fake Microsoft Word document file. If contents from the .zip file are manually extracted it will unpack another file that is usually a JavaScript file, JScript Encoded file, or VBScript Script file. When the file is manually executed by the user it will cause the malware to spread across the machine and begin the file encryption process.

Legion ransomware encrypts files that match certain file extensions with RSA and AES encryption ciphers. Once the encryption process is finalized it will render the files inaccessible to the user. The files are appended a new file extension at the end of the file name and given a new file type. The file name will become randomized or be appended a pattern such as [unique_id][identifier].File_Extension.  A ransom note (or series of ransom notes) in .html and text formats will be placed in every folder the virus encrypted files in and on Windows desktop. In addition, Windows desktop might also change to an image of the ransom note and an image file of the ransom note will also be left in every folder the virus encrypted files in.

To further complications, a lock-screen may also be used to restrict access to the infected machine. A lock-screen is typically used to display a message from the malware author or distributor to the victim. The lock-screen acts as a ransom note or deceptive entity and contains steps to make a payment.

It is suggested to avoid paying ransomware authors to decrypt your files. Luckily, this ransomware has free removal and decryption programs listed below. Third-party programs Shadow Explorer, PhotoRec, or Recuva can also be used to potentially recover files encrypted by this virus. A user may also be able to retrieve encrypted files by performing a system restore to a date and time before the infection occurred.
