Cryptowall 3.0 Decryption?
I am looking for any insight into any successful methods of dealing wit files that were encrypted by the Cryptowall 3.0 malware. Has anyone had any success with this process?
The only "Successful" method is to remove the infection, delete the files and restore them from your backups.
I just finished an article on ransomware infections (not published yet) and the only thing that was of any use was prevention. If you have either shadow copies or backups you may have a better chance (some iterations of the ransomware will encrypt the shadow copies as well). For prevention check out http://www.foolishit.com/v
The only way is to restore files via restore point or a backup, however you could check the following:

the only removal/decryption is for the original cryptolocker, AFAIK. The best info is on bleepingcomputer. Here are some references:

cryptowall and variants use the current state of the art cryptography that the internet depends on with the long keys used AND current technology (even putting the file in a ramdisk) it will take decades if not longer to find the key that will decrypt 1 file even if you had the original source to compare against so unless you plan to need the file in the next millennia you can't reasonably expect to be able to decrypt it. .. The file is gone your only real choice is restore from backup or other saved copy of the file.
Have a look at the Bleeping Computer article http://www.bleepingcomputer.com/virus-removal/cryptowall-ransomware-information for a description of Cryptowall and various strategies.
