Polyglot Ransomware Description

The Polyglot Ransomware is a new malware strain that appeared in late August. This particular type of ransomware captured the interest of the security researchers because it imitates the features of one of the most popular threats – CTB-Locker. The graphical user interface, the language switch and the sequence for requesting the encryption key are almost the same as CTB-Locker. The designers of the threat have copied very closely the style of the famous ransomware, and this is one of the reasons why its name is Polyglot.

Polyglot Ransomware – Distribution

The main route of infection for the Polyglot ransomware is through spam email messages. The message body contains a link to a malicious RAR file archive that includes the executable code of the threat.

Polyglot Ransomware – More Details

Upon infection, the ransomware copies itself under random names in a lot of system locations, adds itself to the autostart folder and to the Windows Task Scheduler. When the installation is complete, the encryption is started. The actual file names do not change. However the user is denied access to their contents. The user files are packed into ZIP archives and encrypted with the AES-256 cipher.

The desktop wallpaper is changed to display the ransom message. The interesting thing with this strain of ransomware is that the generated image is unique to each victim. Like other popular ransomware types, the Polyglot threat also offers the users to decrypt several files for free.

A time limit is displayed to blackmail the users into paying the ransom fee. The malicious code contacts the remote C&C servers, located on the TOR network, to retrieve the exact sum of the ransom and the bitcoin address to which it should be sent by the victim.

If the user does not pay the money, the software notifies the victim that it is no longer possible to restore access to the affected files.
According to the detailed analysis conducted by security researchers, Polyglot was created independently from CTB-Locker.

A team of researchers from Kaspersky have uncovered a mistake in the ransomware’s key generator that allowed them to create a decryptor. You can use it to recover the affected file from the malware.

It is called “Smash Rannoh & Co” and also works for other ransomware variants such as: Rannoh, AutoIt, Fury, Crybola, Cryakl, CryptXXX. You can get it from the specialist site developed by Kaspersky Labs.
