How does Cryptowall work?

If you open a folder related to an encrypted file and then try to open this file, you will be presented with a message explaining the Cryptowall encryption. Here is an excerpt.

All of your files were protected by a strong encryption with RSA-2048 using Cryptowall. […]
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.

Within the same folder you are likely to find decrypt_instruction.url, decrypt_instruction.txt and decrypt_instruction.html files. These are used to manage the encryption. If you click the URL file, you will be presented with a different alert explaining that you need to pay 500 US Dollars or Euros in order to have all the files encrypted. Furthermore, the alert informs you that if you fail to pay the ransom before a set deadline, the ransom fee will be doubled. Anti-Spyware-101.com researchers do not recommend wasting 500 or 1000 USD/EUR because there is another way to delete the infection and defeat the file paralysis.

Can you decrypt Cryptowall?

Our malware researchers are familiar with Cryptorbit, CryptoDefence and Cryptolocker – the clones of the malicious Cryptowall Trojan. It has been revealed that all of these threats can use corrupted spam email attachments and fictitious update installers to slither into your personal computer. Once installed onto the PC, these infections are set to send a decryption key to those who pay the ransom. In the case of CryptoDefence, the certificate key was placed on the affected machine itself. Therefore, we suggest that you look for this key (.cert, .crt, .pfx) in your own folders first. Some computer users find it in folders under %AppData%, %TEMP% or %Program Data%.
