July 6 challenge -- deface 6,000 Web sites On Sunday, a competition known as "the Defacers Challenge awards points to malicious hackers who successfully compromise an organization's Web server and deface its Web pages" reports
IDG News. "Windows servers count for 1 point, while HP-UX and Macintosh servers count for 5."
It could be a joke/hoax, but
Internet Security Systems' Web site says: "We are raising the AlertCon Level to 2 in light of the defacement challenge currently scheduled for Sunday July 6, 2003. We strongly encourage System Administrators to review their current security policies and ensure that all current and known security issues have been addressed."
