Inpivx provides source code for the file-encrypting (symmetrical, AES encryption + RSA public-key cryptography) malware and for the management dashboard for a specific price.

The package costs $500, a very attractive price considering that a single victim paying the ransom may cover the “investment”” and leave some profit. The decryption tool is included.”
