Almost every day we hear about cases of ‘Ransomware’ affecting running servers – an act we call digital terrorism. Let’s get a quick understanding of this risk and the preventive measures to mitigate it. Crypto-ransomware gains access to a target server and encrypts all the files on that server. It scrambles the contents of the file so that you can’t access them without a particular decryption key that can correctly unscramble it. This makes the users or the administrators of the server helpless, and there are no known tools that can detect the hashing algorithms and then decrypt them. A ransom is thus demanded in exchange for the decryption key.
