Masok Ransomware

Masok Ransomware Description

Cybersecurity researchers spot new data-locking Trojans daily. One of the most recent ones goes by the name Masok Ransomware. When inspected, the Masok Ransomware revealed to be a variant of the STOP Ransomware.

Propagation and Encryption

It is yet to be determined with any certainty what is the specific propagation method that has been employed in the spreading of the Masok Ransomware. Some experts believe that the creators of the Masok Ransomware have used the conventional methods of propagating ransomware threats – mass spam email campaigns alongside bogus software updates and pirated fake copies of various applications. When the Masok Ransomware manages to infiltrate a system, it will start the attack with a brief scan. The scan is used to determine the locations of the files, which will be marked for encryption. Then, the Masok Ransomware will begin locking the marked files. Once the Masok Ransomware encrypts a file, it will alter its name by adding a '.masok' extension at the end of the filename. As an example, we can mention that an audio file, which was named 'Onyx-and-Peridot.mp3' previously, will be renamed to 'Onyx-and-Peridot.mp3.masok' once the encryption process is completed.

The Ransom Note

In the next phase of the attack, the Masok Ransomware will drop a ransom note called '_readme.txt' and reads:
