Unknown attackers downed the largest recorder of Web site defacements on Sunday, the same day that vandals had been thought to be planning an online graffiti contest.
The attack left the security site Zone-H.org mostly inaccessible until late Sunday and the effects of the contest largely in dispute. While some 500 Internet addresses corresponding to defaced Web sites were submitted to Zone-H.org, the intermittent accessibility of the site meant that hundreds, if not thousands, more may have not been recorded. "We"ll likely know over the next 36 hours," Roberto Preatoni, founder and editor of Zone-H, wrote Sunday during an Internet chat with CNET News.com.
Word of the contest spread quickly late last week after news reports and security company Internet Security Systems publicized the event. A Web site called the Defacers" Challenge urged online vandals to crack into as many Web sites as possible on Sunday and report the defacements to Zone-H, a neutral third party. While Preatoni expected between 20,000 and 30,000 registrations of hacked sites Sunday, far fewer came in. The lack of response, while apparently due to the trouble that scofflaws had in contacting Zone-H, could also be an indication that the rash of Web site attacks was mainly a flop.
Zone-H.org is best known for its database archiving the snapshots of Web sites that have been defaced. The Web site had to open an alternative page for taking submissions for the contest. Preatoni said he normally sees anywhere between 1,000 and 3,000 Web site defacements on any given Sunday.
