RE: [Full-Disclosure] Re: [normal] RE: Windows Dcom Worm planned DDoS

["Marc Maiffret" <marc@eeye.com>]

Everyone seems a little confused on the windowsupdate.com DDoS. It is a
rather mute point as it is easily fixable. They just need to remap it to
127.0.0.1 and all the SYN's will die on the local host of the infected
machine. Routing windowsupdate.com to 127.0.0.1 will not break anyone's
ability to get patches as "windowsupdate.com" is not directly used.

That is only a workaround for this single host attack though, in the end
everyone (even patched people) can get screwed by this flaw and new worms
until enough people have patched.
