A server being compromised or hacked for the purpose of this guide is an unauthorized person or bot logging into the server in order to use it for their own, usually negative ends. However, the majority of compromised servers are carried out by bots i.e. automated attack programs, in-experienced attackers e.g. “script kiddies”, or dumb criminals. These sorts of attackers will abuse the server for all it’s worth whilst they have access to it and take few precautions to hide what they are doing.
