Detailed Information of .Merry Ransomware


The .merry virus file extension is a trait of the so-called Merry Christmas ransomware. This crypto virus is written in Delphi and uses custom encryption algorithm. Once the threat is running on the computer it will scan all disks and drives for particular data that is set as a target in its code. The target data list may include the following types of files:

  • Documents.- .docx, .doc , .dox , .pdf, .pptx, .txt, etc.
  • Music and other audio – .mp3, .wma, .amr, etc.
  • Photos – .jpg, .png, .jpeg, .svg and other
  • Videos – .mp4, .avi, .flv, etc.
  • Files associated with games
  • Files linked to other commonly used Software

All encrypted data gets the file extension .merry appended after the file name. The files can’t be open by any program and remain unusable until the specific decryption key is applied. The decryptor and the decryption key are held by the malicious intenders and they demand a ransom in order to deliver them to the victims.

A ransom note is yet another Merry Christmas ransomware feature. The threat is programmed to drop a file named MERRY_I_LOVE_YOU_BRUCE.HTA that serves as a message from the ransomware creators. The source code of the threat is programmed to open automatically the file and display it as dynamic desktop wallpaper. It is dynamic as there is a timer that is counting down the remaining time before all encrypted files will be deleted. Тhe wallpaper depicts thematically an evil Santa robot and huge bomb that is going to explode. The whole ransom text reads:

TELEGRAM @comodosecunty
EMAIL [email protected]
Any attempts to return your files with the third-party tools can be fatal for your encrypted files! The most part of the third-party software change data within the encrypted file to restore it but this causes damage to the files.
Finally, it will be impossible to decrypt your files! There are several plain steps to restore your files but if you do not follow them we will not be able to help you!”

There is no information about the exact ransom amount but it is probably required to be in BTC. However, we advise all victims to avoid contact the crooks using the stated addresses.
