How to decrypt files infected by JobCrypter Ransomware?

For managing the work of the decryptor you will need to ‘tune’ the application a bit.

You need to find the original version of any encrypted file. If it’s not possible, then use any encrypted PNG file and a random PNG picture from the Internet. Drag both files to the decryptor executable – this will initiate generation of master key. NOTE that this can take up to several days.
