From the given definition, deface is altering an appearance of something. When applied to web penetration, literally it is the modification of a website’s certain page/changing of a website’s visual appearance. It can be, taking a webpage down (delete) and replacing with a new modified one, or putting of images/scripts/texts that are not present in the original webpage/site.

There could be a lot of reason why hackers target websites and ended defacing it, so why do hackers deface websites?

  • For security purposes:
    I see a lot of defaced websites where messages are popping up “zero security, please secure your website admin!” . It targets the security personnel of the website to highlight security flaw.
  • Just for fun:
    There is a lot of these, mocking the administrator. “You are maintaining this website but what the f*ck are you doing.”
  • For Protest:
    In today’s age, in the rise of anonymous, this is the common reason of a website being defaced. Mass website defacements in an operation. Hacktivism, an online protest, wherein hacktivist protest a message or a cause of (their) belief.
  • Others:
    A quick example, to this is bringing someones/business reputation down.
