Good evening,

I have a computer that has been infected with an encryption ransom-ware virus.  Looking around online none of the tools out there seem to work with the specific variant that I have.  The files were not given a new extension, they're just no longer accessible.  I was hoping to try and use https://www.decryptcryptolocker.com, but the site appears to have shutdown.  Does anyone know of another place where someone has stored the known keys for the older version of this virus? 

 

Thanks

Hi there,

Chances that you are not infected with the original CryptoLocker as it has been down for years.

Do you happen to keep a copy of a ransom note? That can help in identifying the actual infection.

Regards,
Alex

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
About_Files

These are common locations malicious executables may be found:
%Temp%
%AppData%
%LocalAppData%
%ProgramData%
%WinDir%
C:\<random>\<random>.exe

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

The ransom notes are in a few places.  Here is a copy of the note:

 

What happened to your files ?
All of your files were protected by a strong encryption with RSA-2048 using CryptoWall 3.0.
More information about the encryption keys using RSA-2048 can be found here: http://en.wikipedia.org/wiki/RSA_(cryptosystem)

What does this mean ?
This means that the structure and data within your files have been irrevocably changed, you will not be able to work with them, read them or see them,
it is the same thing as losing them forever, but with our help, you can restore them.

How did this happen ?
Especially for you, on our server was generated the secret key pair RSA-2048 - public and private.
All your files were encrypted with the public key, which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program, which is on our secret server.

What do I do ?
Alas, if you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed.
If you really value your data, then we suggest you do not waste valuable time searching for other solutions because they do not exist.

For more specific instructions, please visit your personal home page, there are a few different addresses pointing to your page below:
1.http://6i3cb6owitcouepv.payoptvars.com/1Q2wRt8
2.http://6i3cb6owitcouepv.payforusa.com/1Q2wRt8
3.http://6i3cb6owitcouepv.paywelcomefor.com/1Q2wRt8
4.http://6i3cb6owitcouepv.payemarateslines.com/1Q2wRt8

If for some reasons the addresses are not available, follow these steps:
1.Download and install tor-browser: http://www.torproject.org/projects/torbrowser.html.en
2.After a successful installation, run the browser and wait for initialization.
3.Type in the address bar: 6i3cb6owitcouepv.onion/1Q2wRt8
4.Follow the instructions on the site.

IMPORTANT INFORMATION:
Your personal page: http://6i3cb6owitcouepv.payoptvars.com/1Q2wRt8
Your personal page (using TOR): 6i3cb6owitcouepv.onion/1Q2wRt8
Your personal identification number (if you open the site (or TOR 's) directly): 1Q2wRt8

Anyone have any suggestions, or is the data gone?

 

Thank you.

Hello,

Please read below for information about CryptoWall 3.0 as it is what you have.

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0 & CryptoWall 3.0 is provided by Grinler (aka Lawrence Abrams), in this topic: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

Reading that Guide will help you understand what CryptoWall (including versions 2.0 & 3.0) does and provide information for how to deal with it. Cryptowall typically deletes all Shadow Volume Copies with vssadmin.exe so that you cannot restore your files via System Restore or using a program like Shadow Explorer...but it never hurts to try. At this time there is no fix tool and Decryption of any CryptoWall Files...is impossible since there is no way to retrieve the private key that can be used to decrypt your files without paying the ransom.

There are also lengthy ongoing discussion in these topics:

To avoid confusion I have asked a Moderator to close this topic. If you have any questions please post in one of the two discussion topics above.

Regards,
Alex
