The web hacking incident database (WHID) is a project dedicated to maintaining a list of web application-related security incidents. The WHID's purpose is to serve as a tool for raising awareness of the web application security problem and provide information for statistical analysis of web application security incidents. Unlike other resources covering website security, which focus on the technical aspect of the incident, the WHID focuses on the impact of the attack. To be included in WHID an incident must be publicly reported, be associated with web application security vulnerabilities and have an identified outcome.

An analysis of recent web hacking incidents performed by Breach Security Labs shows that Web 2.0 sites are becoming a premier target for hackers. Based on analysis of recent 'web hacking incidents of importance,' Breach Security Labs found that:

• The first half of 2009 showed a steep rise in attacks against Web 2.0 sites. This is the most targeted vertical market with 19% of the incidents.
  
• Organizations have not implemented proper web application logging mechanisms and thus are unable to conduct proper incident response to identify and correct vulnerabilities.
  
• Attack vectors exploiting Web 2.0 features such as user-contributed content were commonly employed.
