Then, 7ev3n spreads multiple text file copies of the ransom message.

Here is what the ransom message states:


All your documents, photos, databases, office projects and other important files have been encrypted with strongest encryption algorithm and unique key, original files have been overwritten, recovery tools and software will not help. Private key is stored on a server and nobody can decrypt your files until you pay and obtain the private key.

This is not a complete list as there might be other file extensions that are encrypted. It changes the file extension of all encrypted files to .r5a.

The 7ev3n ransomware demands a really high sum of money for decryption compared to many different ransomware types. As you can see from the ransom note, 13 BitCoins is a lot. Now, as this article is being written, that is around 5140 dollars. In the ransom note, there are even examples being given from where to buy BitCoins.
