The defacement of a company's website (or of several websites in the case of mass defacement) is achieved via security holes in web servers, which enable attackers to change the website content and design. Sometimes, such attacks are politically motivated, carried out by so-called « hacktivists ». Depending on how much a company relies on its website for business continuity, the consequences of such attacks can range from a tarnished image to substantial financial losses. 

Effects and risks

  • loss of reputation
  • financial loss
  • Misuse of the vulnerability for other attacks  


  • A website must be adequately protected. This includes all updates and the server software as well as the content management systems (CMS) it contains.

  • Particular attention must be paid to settings.
