Hi guys don't really know where to put this because I don't know what is causing it.  I was infected with cryptolocker and the 4 files can still be found in just about every folder on the computer however the infection is no longer active?  I don't get the messages anymore when I reboot/log in.

 

After the infection was removed everything seemed fine.  That was a couple months ago. Last night I needed a picture and I went back to get it and found out all my thumbnails are gone (they show the place holder and file name but not the picture) and the pics wont open on an entire hard drive and scattered throughout the computer.  (I localize most pics on one drive) The video files are ok though.  I have been searching the web and downloaded data repair (stellarphoenix).  Tried photo shop because I read that it would open files with bad headers.  Tried gimp.  Tried my linux box.  When I look on the network linux cannot even see the files.  Tried the following command at C: assoc .jpeg=jpegfile and get access denied error occurred while processing jpeg.  

 

In some folders half the files are there and half are not.  I originally noticed when I clicked on the image and got this message.  "windows photo viewer can't open this picture because the file appears to be damaged, corrupted or is too large.

 

Sadly this is years and years of family photos.  Naturally no system restore or backup.  : (  I've been meaning to get these sorted out and copies made for the kids yada yada).

 

The best I can figure out is the headers are all changed.  I thought it might be encryption from cryptolocker but I uploaded one of the images to try and get the key using the firefox program but it said this was NOT a file infected by cryptolocker.  I have been thinking it is a permission thing in windows or maybe win 7 ultimate is behind it somehow (I saw this mentioned on a thread)  But the files don't show up in linux either.    I don't know what happened to these files but I hope I can get them back they are not overwritten.

 

Thanks so much.

 

Yours

Hello,

This sounds like another ransomware infection. The real CryptoLocker was taken down long ago.

Can you copy the contents of one of the ransom note? Or at least the name, so it can be identified?

Regards,
Alex

Hi I got the pop ups to stop using bleeping computer and a guy from Malwarebytes sent me a script that ran with one of the programs.  This is the ransom note.  I no longer get popups when starting the computer but these files are everywhere, in just about all the folders.  I delete them when I see them and they don't come back so I do not think the infection is active.
 
Thanks
 
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:
 
If for some reasons the addresses are not available, follow these steps:
2.After a successful installation, run the browser and wait for initialization.
3.Type in the address bar: paytoc4gtpn5czl2.onion/dv36xR
4.Follow the instructions on the site.

It looks like you are infected with CryptoWall.

Please see the following quote from Global Moderator quietman7 for more information.

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:

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 that topic discussion.

To avoid confusion, I have asked a Moderator to close this topic.

Regards,
Alex
