.Promock Extension is a newly detected threat in the family of ransomware that encrypts most of the files on the attacked PC. Security researchers had reported that the threat uses AES-256 and RSA-2048 encryption algorithm to encode files on the attacked PC and appends ‘..Promock’ extension to the encrypted files. It is analyzed that the .Promock Extension mostly targets English and Russian-speaking users. And is distributed through phishing email campaigns similar like Dream_dealer@aol.com Ransomware. Unfortunately, if the user downloads the infected mail attachment that is actually a macro-enabled document containing the payloads of the virus. Upon clicking, the document starts running the script and .Promock Extension gets installed on the attacked computer system.

The infection uses AES cipher to transcode the data that are locked by the filename and the‘.Promock’ suffix. For example, blackcat.jpg is renamed to blackcat.jpg..Promock. After the encryption process been done, then the Ransomware drops a file named as ‘README_FOR_DECRYPT_YOUR_FILES.txt’ on the desktop and the encryption locations.
The ‘README_FOR_DECRYPT_YOUR_FILES.txt’ file reads as:
‘All of your files have been Encrypted with military grade system and impossible to brute force, cracking, or reverse engineering it !
