Six Apart Blogs Brought Down by Redirected Denial of Service Attack
Posted on May 5, 2006
Security Pro News reports that this weeks Six Apart outage was caused by a redirected denial or service attack or DDoS. Apparently, the DDoS attack was really meant for Blue Security's .com domain but they pointed the bluesecurity.com domain to their blog on blogs.com, which forced the DDoS attack onto TypePad and the rest of Six Apart's network of blog services. Jason Levin explains in a recent post.
Because according to a post on the North American Network Operators Group mailing list, at some point yesterday the people at Blue Security decided that the best way to deal with the attack was to point the hostname www.bluesecurity.com to their TypePad-hosted weblog, bluesecurity.blogs.com. This effectively meant that the target of the attack shifted off of Blue Security's own network and onto that of Six Apart, and did so as the direct result of a decision made by the folks at Blue Security.Six Apart's TypePad, LiveJournal and other service were all affected earlier this week by the DDoS but they are all back online now.
