Hello,

 

     I have viewed all of the guides on this forum regarding Crytowall viruses and removal, but I'm still at a bit of a loss. To remove the virus I've decided the easiest way is going to be a full format of the computer, just do to the length of time it's been active (Since Nov. 2014). My issue is, there are pictures on the computer that I can't get back. There used to be a website (DecryptCryptowall) that would analyze a file you send to them and email you back a decryption key, however, that website has been decommissioned. The pictures on the computer are all pictures of my family, that I'm sad to say, I can never take again. I'm not willing to pay any ransom for them as I refuse to support these people, even if it means losing something very priceless to me. From what I've read, many people are in the exact same boat as me on this one. Does anyone know if there is a way to decrypt my files? All my restore points have been deleted. My shadow restore points were deleted. There was nothing in data recovery. This is kind of my last try at getting my files, as I've done many hours worth of reading on the subject, but with no luck.

 

Kind Regards,

Lobtercraws

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

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. CryptoWall ransomware encrypts data using RSA encryption...everyone has their own individual private key which cannot be used with someone else's encrypted files. CryptoWall generates the individual private keys on their C2 server and only the public key is sent over the wire.

There are also ongoing discussions 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 one of those topic discussions. 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
