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 and fake ransomware variants which use the CryptoLocker name but those infections are not the same. As such, I split your posting into its own topic and have advised our Security Colleagues who specialize in crypto malware ransomware with a link here.

I read a couple similar reports last year (around Sept-Oct 2015) but neither provided any information as to what specific ransomware encrypted the data and appended a .krypted extension to the end of the file name.

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:
HELP_DECRYPT.TXT, DECRYPT_INSTRUCTION.TXT, HELP_TO_DECRYPT_YOUR_FILES.txt, HELP_YOUR_FILES.TXT
HELP_FILE_[random number/letter].HTML, install_tor.url, ATTENTION.RTF, DecryptAllFiles.txt
Read.txt, ReadMe.txt, README1.txt...README10.txt, READ_IF_YOU_WANT_YOUR_FILES.html
README_IMPORTANT.TXT, IMPORTANT READ ME.txt, README_FOR_DECRYPT.txt, READ!!!!!!!!!!!.ME.txt
_Locky_recover_instructions.txt, ReadDecryptFilesHere.txt, README!!.TXT, DecryptAllFiles_.txt
YOUR_FILES.HTML, YOUR_FILES.url, encryptor_raas_readme_liesmich.txt, Help_Decrypt.txt
HELP_RESTORE_FILES.txt, HELP_RECOVER_FILES.txt, HELP_TO_SAVE_FILES.txt, ABOUT_FILES!.txt
DECRYPT_INSTRUCTIONS.TXT, How_To_Recover_Files.txt, How_To_Restore_Files.txt, Coin.Locker.txt
HOW_TO_DECRYPT_FILES.TXT, HOW TO DECRYPT FILES.TXT, DECRYPT MY FILES#..txt, read_it.txt
_secret_code.txt, DECRYPT_ReadMe.TXT, BLEEPEDFILES.TXT, AllFilesAreLocked_.bmp, WHAT IS SQ_.tx

help_decrypt_your_files.html, RECOVERY_FILES.txt, RECOVERY_FILE.TXT, RECOVERY_FILE_[random].txt
Howto_RESTORE_FILES_.txt, Howto_Restore_FILES.TXT, howto_recover_file_.txt, HELP_TO_SAVE_FILES.txt
how_recover+[random].txt, _how_recover_.txt, restore_files_.txt, recover_file_[random].txt

_ReCoVeRy_+[5_random].txt, Recovery_[5_random].txt, RECOVERY.TXT, RECOVERY_KEY.txt

Note: The [random] represents random characters which some ransom notes names may include.
Samples of any encrypted files, ransom notes or suspicious executables (installer, malicious files, attachments) that you suspect were involved in causing the infection can be submitted here (http://www.bleepingcomputer.com/submit-malware.php?channel=3) and here (http://www.bleepingcomputer.com/submit-malware.php?channel=170) with a link to this topic. Doing that will be helpful with analyzing and investigating by our crypto experts.

I haven't received any ransom note so I don't know what this virus or malware is. I don't know what to do.

.krypted Ransomware has already been reported...in this topic so I am merging yours with that one to make it more manageable for staff and our crypto malware experts.

Unfortunately, there is not a lot of information so if you can submit samples of any files to the channels noted in Post #2, that would be helpful.

Thanks
The BC Staff

My Computer has been attacked by some virus, All my important ms excel files has been change to ".krypted" extension and also got below message from hacker 

 

"You've been KryptoLocked!
All of your files have been encrypted and sent to our secure server.
You can verify this by checking your files.
Encryption was produced using a unique public key generated for this computer.
To your decrypt files, you need to obtain your private key.
To obtain your private key you will need to pay the fee of 1 BTC.
Upon payment you will receive your key and decrypter. We will also delete your files from our server.
This is a very straight forward process and you can recover your files within minutes.
There is no other way to recover the files without the unique private key.
To recover your files please get in touch by email: krypted@riseup.net"
 
Please give some idea to get rid of this extension changed issue so i can get back my important files
 
Thanks
