 good morning , I could find out that you are an experts on the subject. I'm a man from Barcelona (Spain) that suffered the attack of a Bad hacker, please, you could have a look at my files. I'd appreciate it a lot. There are many memories of my family unrecoverable.

I'm afraid you were hit with CryptoWall 4.0. If you do not have any backups, then there is no way to restore your files.

 

You can check these links for more information.

There are several variants of CryptoWall but it does not change the file extension of the file it encrypts.. The original CryptoWall leaves files (ransom notes) with names like DECRYPT_INSTRUCTION.TXT, DECRYPT_INSTRUCTION.HTML, and DECRYPT_INSTRUCTION.URL. CryptoWall 2.0 leaves ransom notes named install_tor.url. CryptoWall 3.0 leaves ransom notes named HELP_DECRYPT.TXT, HELP_DECRYPT.HTML, and HELP_DECRYPT.PNG CryptoWall 4.0 leaves ransom notes named HELP_YOUR_FILES.TXT, HELP_YOUR_FILES.HTML and HELP_YOUR_FILES.PNG. CryptoWall 4.0 will encrypt the actual filename of an encrypted file as well as the data contained in it. Each encrypted file will have a unique name with random characters (0ausbffwh.p5, 72lcvn.iv6nn, x83o8x.ux7, etc) as described here.

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 this topic: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

Unfortunately as noted by Demonslay335 there is no fix tool and decryption of 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. 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. As with most ransomware infections...the best solution for dealing with encrypted data is to restore from backups. If that is not a viable option, the only other alternative is to save your data as is and wait for a possible breakthrough...meaning, what seems like an impossibility at the moment (decryption of your data), there is always hope someday there may be a potential solution so save the encrypted data and wait until that time.

Most security experts will advise against paying the ransom demands of the malware writers because doing so only helps to finance their criminal enterprise and keep them in business. The more people pay the ransom, the more the attackers are encouraged to keep creating ransomware for financial gain. Further, there is no guarantee that paying the ransom will actually result in the restoration (decryption) of your files. And since ransomware can be responsible for dual infections that means paying both ransoms in order to decrypt data. Decreasing your chances for recovering data with dual infections is that files may get encrypted multiple times, especially if the victim had tried to fix the files by renaming them first while the malware was still active...resulting in further problems and complicating possible decryption.Grinler, (aka Lawrence Abrams), the site owner of Bleeping Computer has said this...

...Though the loss of your data and computer can be devastating, sending the ransom could be even more so. Depending on how the criminals want you to pay the ransom could put you at risk for Identity Theft as the information you send may contain personal information. Therefore, we suggest that you never pay a ransom unless it is absolutely necessary for data recovery...Last, but not least, it is important to remember that paying the ransom only continues to fuel the release of new variants of these types of programs.

Since many victims know there is no guarantee with paying the ransom, some ransomware developers and Hackers are now offering customer support and live Support Chat to help with decryption. Then the question becomes....should I trust that support?

With that said...We understand some folks may feel they have no other alternative but to take a chance and pay the ransom in hopes of recovering irreplaceable photos and other personal or important data. That is a choice and a decision each affected victim will have to make for themselves. We will not make any judgments for doing so.

There are ongoing discussions in these topics where you can ask questions and seek further assistance for the CryptoWall variant you are dealing with.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 the topic discussion related to the variant you are dealing with. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.

Thanks
