Some of my users got an email today about a fax, and despite it looking very suspicious a few people opened it anyway.  It looks like the files that were encrypted are strictly on the employee's workstation and did not hit the network shares.  In looking at the CRYPTLIST under HKCU\Software\"random code" everything is on the local machine, or if on the terminal server, the one user's profile.  I have no qualms about reimaging the workstations.  I'm guessing on the terminal server I can just delete the user's profile and create a new one.  I proposed blocking executables in %AppData% months ago, but got voted down due to line of business software we use that requires running in that location.  Argh.

CryptoWall is CryptoDefense rebranded with a new name.

A repository of all current knowledge regarding CryptoDefense is provided by Grinler (aka Lawrence Abrams), in this tutorial: CryptoDefense and How_Decrypt Ransomware Information Guide and FAQ

Reading that Guide will help you understand what CryptoDefense and How_Decrypt Ransomware does and provide information for how to deal with it and possibly decrypt/recover your files.

There is also a lengthy ongoing discussion in this topic: New Crypto variant? CryptoWall...CryptoDefense with a new name. Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that topic discussion.
