Emsisoft Decrypter for Al-Namrood will decrypt the Al-Namrood variant of the nasty Apocalypse ransomware.

This strain attacks servers that have remote desktop services enabled. The files encrypted by Al-Namrood are renamed to .disappeared or .unavailable and the ransom note will appear with a .Read_Me.txt extension. Once infected, you will be instructed to contact "decryptioncompany@inbox.ru" or "fabianwosar@inbox.ru." Note that the 'fabianwosar' email address is another insult against Emsisoft's own Fabian Wosar. These criminals sure have a dislike for him.

The ransom note reads as follows:

Hello!
