A client of ours has been hit with a cryptolocker virus. The client uses a Domain controller running Server 2003 which we are in the process of upgrading.
They also use drop box & recently this has been compromised.
Attached are the file types which are contained in each subfolder that has been encrypted.
We are currently running Sophos Enterprise 5.2.1 R2. Any advice would be appreciated as we are unable to restore unless we pay the ransom fee.
