The original Cryptolocker infection has been down for a while now and has not returned. There are several copycat and fake ransomware variants which use the CryptoLocker name but the infection is not the same.

Are there any file extensions appended to your files...such as .ecc, .ezz, .exx, .xyz, .CTBL, .CTB2, .XTBL, .encrypted, .vault, .HA3, .toxcrypt or 6-7 length extension consisting of random characters?

Did you find any ransom note? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a random named .html, .txt, .png, .bmp, .url file.

These are some examples.
HELP_DECRYPT.TXT, HELP_DECRYPT.HTML, HELP_DECRYPT.URL, HELP_DECRYPT.PNG
HELP_TO_DECRYPT_YOUR_FILES.bmp, HELP_TO_DECRYPT_YOUR_FILES.txt, HELP_RESTORE_FILES.txt
HELP_TO_SAVE_FILES.txt, HELP_TO_SAVE_FILES.bmp, RECOVERY_KEY.txt
DECRYPT_INSTRUCTION.TXT, DECRYPT_INSTRUCTION.HTML, DECRYPT_INSTRUCTION.URL

Once you have identified which particular ransomware you are dealing with, I can direct you to the appropriate discussion topic for further assistance.

Hi Quietman,

 

I have also been infected by this silly virus and hope you can help. I found numerous posts on how to remove the virus which seemed to have worked but I don't have previous versions of any of those files. Are you able to help decrypt my files? They're mostly pics and have a ZZZ file extension. The Ranson note says it's been done using Cryptowall 3.0. 

 

Really hope you can help.

 

Thanks in advance

legendgp,

It looks like you are co-infected with both CryptoWall 3.0 and a variant of AlphaCrypt.

The discussion topic for CryptoWall 3.0 is here and a knowledge base is here.

Discussion topic for AlphaCrypt is here and a knowledge base is here.

Unfortunately there is no way to decrypt files encrypted by both ransomware.

If you have any questions it is best to post in the respective discussion topics.

Any files that are encrypted with the newer unnamed variant of TeslaCrypt/AlphaCrypt will have the .exx, .xyz or .zzz extension appended to the end of the filename.

With dual infections, that means paying both ransoms. Brute forcing the decryption key is not a realistic option.

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 one of those topic discussion links provided by Alex. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.

Thanks
