According to the Web Hacking Incidents Database, which is maintained by the Web Application Security Consortium (WASC), stealing money or data still may not be the biggest motivating factor for hackers, although attacks involving data thefts certainly have been on the rise in recent years.
Most of the Web-site defacements among the studied attacks "were of a political nature, targeting political parties, candidates and government departments, often with a very specific message related to a campaign," the report said. "Others [had] a cultural aspect, mainly Islamic hackers defacing Western Web sites."
An Italian blogger, Giorgio Maone, documented recent Islamic attacks targeting the U.S. and Israel for what it claimed as killing children and civilians.
