How to decrypt files infected by JobCrypter Ransomware?
Use the decrypting tool
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.
When the detecting on the encryption code is finished, you will see an info window, simply click OK. Now you can start decryption – choose folders and click Select. We recommend trying the application out on several files before starting the full decryption.
