Hi

Someone i know just informed me that his HDD was infected with Cryptowall 3.0. 

Seems the time of infection was about 2 years ago or so. Since the infection, he disconnected HDD and was in shelf till now. He's asking me if there are any decryptor for Cryptowall 3.0 specific. 

I wasn't able to locate the right discussion. Please feel free to move it there's a open discussion. 

Thanks

Ransom note as followed 

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://ayh2m57ruxjtwyd5.blindpayallfor.com/7b66za
2.http://ayh2m57ruxjtwyd5.stopmigrationss.com/7b66za
3.http://ayh2m57ruxjtwyd5.starswarsspecs.com/7b66za
4.http://ayh2m57ruxjtwyd5.malerstoniska.com/7b66za

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: ayh2m57ruxjtwyd5.onion/7b66za
4.Follow the instructions on the site.

 

IMPORTANT INFORMATION:

Your personal page: http://ayh2m57ruxjtwyd5.blindpayallfor.com/7b66za
Your personal page (using TOR): ayh2m57ruxjtwyd5.onion/7b66za
Your personal identification number (if you open the site (or TOR 's) directly): 7b66za 

 

Apparently, no file has been encrypted with specific extension but all the files seem corrupted..

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0, CryptoWall 3.0 & CryptoWall 4.0 is provided by Grinler (aka Lawrence Abrams), in the: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

Unfortunately, there is no fix tool and decryption of CryptoWall files...is impossible without paying the ransom since there is no way to retrieve the malware developer's private key that can be used to decrypt your files. For a more detailed explanation, read this reply by Nathan (DecrypterFixer). The only methods you have of restoring your files is explained in the FAQ: How to restore files encrypted by CryptoWall...but there is no guarantee that will work.

There is an ongoing discussion in this topic where victims can post comments, ask questions and seek further assistance but as noted above there is no solution to fix your encrypted files. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in one of the above support topic discussions...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.

Thanks
