Well, this is a first for me. But, my next two blogs will be based on a real life situation that my job is currently combatting. The dreaded CryptoWall has struck our file storage servers and encrypting all necessary documents and leaving behind a ransom note requiring a cash payment on keys for the decryption.
To address this issue we first need to understand what is a CrytoWall?
CryptoLocker/Wall is a ransomware trojan that targeted computers running Microsoft Windows. CryptoLocker/Wall is transmitted via email attachments, web downloads, and even infected USB drives. The malware could be embedded within your system for long periods until it is triggered. Once, active the malware encrypts a particular type of files stored on local and mounted network drives using an RSA public-key cryptography, with the private key stored on the malware's servers. The malware then displays a message that offers to decrypt the data if a fixed deadline makes a payment. If the deadline is not met, then expect to pay a higher price for the key.
Next week I will give an update how we address this issue...
