Are there any file extensions appended to your files...such as .ecc, .ezz, .exx, .zzz, .xyz, .aaa, .abc, .ccc, .vvv, .xxx, .ttt, .micro, .mp3, .encrypted, .locked, .kimcilware, .crypto, _crypt, .crypt, .crypted, .crinf, .pzdc, .good, .R16M01D05, .cerber, .eclr, .sshxkej, .73i87A, .p5tkjw, PoAr2w, .surprise, .coverton, .krypted, .r5a, .XTBL, .YTBL, .LOL!, .OMG!, .RDM, .RRK, .RAD, .encedRSA, .encryptedRSA, .crjoker, .EnCiPhErEd, .LeChiffre, .keybtc@inbox_com, ._cryptcryptcrypt.@.gmail.com_, .id_<victim_id>_email_zeta@dr.com.scl, .0x0, .bleep, .1999, .fu*k (f**k), .vault, .HA3, .frtrss, .toxcrypt, .magic, .enc, .locky, _sq.<filename>, .k2p, .Sanction, .SPORT, .cwgoqia, .trun, .crysis, .xrtn, .SUPERCRYPT, .CTBL, .CTB2, or 6-7 length extension consisting of random characters such as .uogltic, .rpyxhhm, .mtrsxox, .phszfud?

Did you find any ransom note? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. They typically are found in every directory where data was encrypted. 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 randomly named .html, .txt, .png, .bmp, .url file.

These are some examples of ransom notes:

Looks to be CryptoWall 4.0. The first 16 bytes of each encrypted file are the same, and the filenames are encrypted. I've not seen that ransom note name before, they could be switching things up. Were you also the one to upload HELP_YOUR_FILES.PNG around that same time? That was successfully identified as CryptoWall 4.0.

 

Afraid there is no current solution. You can check out more in the support topic.

 

I'll add the new definition for the ransom note for future detections. I have no way of currently automating the detection by the just files, since it's hard to tell what is a "random" filename in code.

Since Demonslay335 has confirmed the infection to be CryptoWall 4.0...rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion. 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
