Hello All,

 

I've had a variant lingering over the course of the year and thought I go here before throwing the towel in. We ended up paying the ransom unfortunately and got nowhere. I've attached the ransom note, encrypted file, and decrypter/readme instructions. I was able to get some files to decrypt but others files are skipped. The decrypter appears to not work correctly.

Years of tax returns and personal photos lost so any help would be greatly appreciated!

What is the actual name of the ransom note?
Are there any obvious file extensions appended to or with your encrypted data files?

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.

DECRYPT_INSTRUCTION.html and no file extensions appended. You can see files in Sendspace link.

CryptoWall Ransomware does not append an obvious extension to the end of encrypted filenames.

There are several variants of CryptoWall but the original left files (ransom notes) named DECRYPT_INSTRUCTION.TXT, DECRYPT_INSTRUCTION.HTML, and DECRYPT_INSTRUCTION.URL.

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, there is no fix tool and decryption of CryptoWall files...is impossible.

This appears to be the variant here: https://www.bleepingcomputer.com/news/security/shoddy-programming-causes-new-ransomware-to-destroy-your-data/

 

Not sure if there is a solution for this yet or not?

Unfortunately I am not aware of any solution. As noted by Grinler, (aka Lawrence Abrams) in that article.

...the sad news is that for anyone who was affected by this ransomware, there is nothing that can be done to retrieve your files and your only option is restore from a backup.
