A repository of all current knowledge regarding CryptoWall
is provided by Grinler
(aka Lawrence Abrams
), in this tutorial: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ
Reading that Guide will help you understand what CryptoDefense does and provide information for how to deal with it and possibly decrypt/recover your files. At this time there is no fix tool for CryptoWall.
There is also a lengthy ongoing discussion in this topic: CryptoWall - new variant of CryptoDefense
. 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.
Note: Although this infection has numerous similarities to CryptoLocker and CryptorBit, there is no evidence that they are related other than that they do the same thing.
