Hi - I have a client who got this ransomeware which apparently is a varient (6th gen) of the Cerber ransomeware.
"All your important files were encrypted on this computer.
You can verify this by click on see files an try open them.
Encrtyption was produced using unique public key RSA-4096 generated for this computer.
To decrypted files, you need to otbtain private key.
The single copy of the private key, with will allow you to decrypt the files, is locate on a secret server on the internet;
The server will destroy the key within 48 hours after encryption completed.
To retrieve the private key, you need to pay 11 bitcoins
Bitcoins have to be sent to this address: 1GoysYnEmxve8sNNaRUvTqK3qfR6Fa7vQZ
After you've sent the payment send us an email to : firstname.lastname@example.org with subject : DECRYPT-ID-6310A11BTC
If you are not familiar with bitcoin you can buy it from here :
SITE 1 : www.coinbase.com
SITE 2 : www.bitstamp.net
After we confirm the payment , we send the private key so you can decrypt your system."
Any assistance with this would be appreciated.
