Web 2.0 is causing a great many security issues for both the user and the organisation. According to Ian de Villiers, senior security developer at Sensepost, Web 2.0 is a new method of using the Internet. According to De Villiers, some security threats include a script that port-scans internal networks while users are simply viewing a Web page, or a worm that exists purely in a Web application. An example of this was the MySpace ? ?Samy is my Hero' worm that infected over a million accounts in less than 24 hours, he says.
