The Al-Namrood ransomware is a fork of the Apocalypse ransomware. The group behind it primarily attacks servers that have remote desktop services enabled. Encrypted files are renamed to .unavailable or .disappeared and for each file a ransom note is created with the name *.Read_Me.Txt.

By default the decrypter will set the ID to the ID that corresponds to the system the decrypter runs on. However, if that is not the same system the malware infection and encryption took place on, make sure to put in the ID as specified in the ransom note.

It is based on a similar ransomware kit called "Stampado" that is written by the same author. To use the decrypter you will require a file pair containing both an encrypted file and its non-encrypted original version. Due to the file name encryption this can be a bit tricky. The best way is to simply compare file sizes. Encrypted files will have the size of the original file rounded up to the next 16 byte boundary. So if a the original file was 1020 bytes large, the encrypted file will be 1024. Select both the encrypted and non-encrypted file and drag and drop both of them onto the decrypter file in your download directory.

Since version 1.17.0 each Stampado infection also has a unique "salt" that is specific to the ransomware buyer. The salt can either be specified manually or detected automatically. In order to determine the salt automatically the ransomware has to be running on the system. Fill in the ID and email address and click the "Detect ..." button next to the salt input field.
If the malware has already been removed, please don't attempt to reinfect yourself. Instead submit the malware file via email to [email protected] so I can extract the correct salt for you. You can also try the pre-configured salts that have been used by known Stampado campaigns in the wild so far.
