Hi infowire :)

You have been infected by Cryptowall. Sadly, at this time, there's no way to decrypt the files that were encrypted by Cryptowall. There's currently a Support thread open for the Cryptowall infection. I suggest you to go post in it to seek assistance and ask your questions. This way, all the information about the Cryptoware will be centralized in one thread and it'll avoid having hundreds of them created for the same issue. The Support thread can be found in the link below.

CryptoWall - new variant of CryptoDefense

Also, Cryptowall runs a command that delete all the Shadow Volume Copy files stored on the system, which prevents you from recovering your files using the "Previous Versions" method. You can always check if you can, in case the command didn't run or didn't run properly. Shadow Explorer is a free program that you can use to navigate throught your shadow copies and can be easier to use in opposition to Windows' native explorer. Also, you can try to use free data recovery software to recover your files, but there's no guarantee that it'll work. Some of these free data recovery software are:Take in consideration that none of these software guarantee that they'll be able to recover everything, if not anything at all. Plus, since they are free software, they have a data recovery limit as well (ranging between 1 and 10GB).

In the future, if you want to prevent this type of infection (Cryptoware) from hitting you again, I suggest you to use one of the programs below to protect your system since they aim at stopping Cryptoware from infecting your system and/or the main process to encrypt your files, on top of having a good back-up plan in place.Meanwhile, if you want to learn more about Cryptowall: how you get infected, how you can prevent it from happening in the future, what methods you can use to try to restore your files, I suggest you to read the Cryptowall FAQ hosted on BleepingComputer.

This being said, I contacted a Moderator to get this thread closed to avoid confusion.

Good luck!

TeslaCrypt/Alpha Crypt leaves files (ransom notes) named RECOVERY_KEY.txt...is that what you are referring too and just assuming it is CryptoWall 3.0? There is no way to confirm from the limited information you provided. Are there any file extensions appended to your files...such as .ecc, .ezz, .exx, .CTBL, .CTB2, .XTBL, .encrypted, .vault, .HA3 or 6-7 length extension consisting of random characters?

Then you are dealing with TeslaCrypt Ransomware and possibly CryptoWall as well if a dual infection. Any files that are encrypted with TeslaCrypt will have the .ecc extension added to the end of the filename. CryptoWall does not change extensions on a file.

A repository of all current knowledge regarding TeslaCrypt and Alpha Crypt is provided by Grinler (aka Lawrence Abrams), in this topic: TeslaCrypt and Alpha Crypt Ransomware Information Guide and FAQ

There is an ongoing discussion in this topic: TeslaCrypt Ransomware Support and Discussion Topic.

Information about and support for decrypting files affected by TeslaCrypt ransomware can be found in this topic:You should post any questions, comments or requests for assistance in one of those topic discussions. To avoid unnecessary confusion...this topic is closed. Send me a PM if you have any questions.
