Anonymous has managed to generate a measurable attack against the Scientology.org Web site. Over the past few days, the site was hit with several DDOS (distributed denial-of-service) attacks, which flooded it with as much as 220 Mbps of traffic, according to Jose Nazario, a senior security engineer with Arbor Networks, whose company compiles data on Internet attacks. The Anonymous campaign shows some level of organization. “220 Mbps is probably about in the middle of attack sizes,” Nazario said. “It’s not just one or two guys hanging out in the university dorms doing this.” On average, the attacks lasted about 30 minutes and used up 168 Mbps of bandwidth. In the past year, Arbor has seen attacks on other sites hit 40 Gbps, or 200 times the strength of the Anonymous event.
