The Internet was hit by this attack last night. Parties unknown exploited the MS SQL vulnerability to launch a distributed denial of service attack which took down much of the Internet, as per this post. Meanwhile, I’d been mulling over a recent security alert that discusses a vulnerability close to the heart of the HTTP protocol. Once again, Vernor Vinge got it pretty much right. His future computer nets weren’t something you jacked into, they were a vast network full of legacy code and unexpected consequences. Sounds about right.
