MMM Reborn is a cryptovirus that encrypts files using RSA + AES algorithms. It demands a huge ransom amount – 222BTC that is equivalent to around 800 000 US dollars. It is a new version of MMM. MMM Reborn already released a few more versions to the wild. Most of the previous versions in the MMM family use AES and RSA algorithm mix for the file locking and demands at least 0.25 BTC. 

Payload

MMM Reborn uses RSA 2048 method or doubles that up with AES128 for the main file-locking process. During the encryption, the original file code is altered and, this way, data becomes unusable. When your files get marked with the appendix, the user can also see the ransom note IF_YOU_NEED_FILES_READ_ME.html on their computer's screen that additionally, to the payment instructions, displays the following text:

All of your files were encrypted by a strong encryption with RSA2048
Specially for your PC was generated personal RSA2048 Key, both public and private
ALL YOUR FILES were encrypted with the public key, which has been transferred to your PC via the Internet
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our Server

MMM Reborn V4

In March 2019 this version came to the attention of researchers with a few new specific features. Firstly, the ransom note in this case delivered in the text file called DECRYPT_FILES.txt as before the message about the attack was shown in an HTML window. Besides the text file with a ransom note, the main executable that launched the script RebornMMM.exe alongside other files like ecorp.bat can be found on the affected system.
