How to decrypt files encrypted by (trojan.cryptolocker)? in Windows Server 2003 used for oracle DB?

After deep search for this kind of encryption, I found that no way to dycrypt files only to pay the ransom and get the password.

Take care of the following in your environment, not to fall in the same situation:

1. Don't publish servers to internet using RDP Default Port3389.

2. Use VPN Connection rather than puplishing.

3. Need to publish resources Use DMZ.

4. Keep an OS image of servers that you don't have support for.

5. Daily Backup of data.

6. Enable Shadow Copy for HDDs, and Versioning for data files.
