The original CryptoLocker Ransomware which first appeared in the beginning of September 2013...does not exist anymore and hasn't since June 2014. There are many copycat ransomware variants which pretend to be or use the CryptoLocker name but those infections are not the same. Any references to CryptoLocker and retrieving keys for it will not work anymore.

In order for anyone to assist you, we need to identify specifically want ransomware infection you are dealing with.

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, ,lock, .locked, .kimcilware, .crypto, _crypt, .crypt, .crypted, .crinf, .pzdc, .good, .R16M01D05, .cerber, .fun, .kkk, .btc, .gws, .eclr, .sshxkej, .73i87A, .p5tkjw, PoAr2w, .surprise, .tzu, .coverton, .krypted, .r5a, .XTBL, .YTBL, .LOL!, .OMG!, .RDM, .RRK, .RAD, .encedRSA, .encryptedRSA, .encryptedAES, .justbtcwillhelpyou, .btc-help-you, .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, .Remind, .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. 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:

Note: The [random] represents random characters which some ransom notes names may include.
You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation.

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

There are several ransomware infections that do not append an obvious extension to the end of encrypted filenames or add a known file pattern which helps to identify it. CryptoWall, CrypMic, DMA Locker, Microsoft Decryptor (CryptXXX), PClock, Spora, Cryptofag, TeslaCrypt v4.0, CryptoHost, MotoxLocker, KawaiiLocker, Hermes, LoveServer and Power Worm do not append an obvious extension to the end of encrypted filenames.

Some ransomware variants (i.e. DMA Locker, TeslaCrypt, CrypMic) will add a unique hex pattern identifier in the header of every encrypted file so the ransomware can identify the file as one it encrypted. Spora-encrypted files utilize a 4 byte long Crc32 file marker. CryptoWall is identified by how the files are renamed. CryptoWall 3.0 and 4.0 encrypted files typically will have the same 16 byte header which is different for each victim.

The best way to identify the different ransomwares that do not append an extension is the ransom note (including it's name), samples of the encrypted files, the malware file itself or at least information related to the email address used by the cyber-criminals to request payment. Without any of that information or a file marker/unique hex pattern identifier, it is difficult to determine what you are dealing with.

If you can find the malicious executable that you suspect was involved in causing the infection, it can be submitted here (https://www.bleepingcomputer.com/submit-malware.php?channel=168) with a link to this topic. There is a "Link to topic where this file was requested" box under the Browse... button. Doing that will be helpful with analyzing and investigating by our crypto malware experts.

Based on current infection rates and statistics, the two most common ransomware variants that do not change the extension or use a filemarker are PClock and Cryptofag.
