Thanks! I retract any comments indicating this had never happened to MS sites. Apparently, Korea isn't a safe place to operate a website, as mozilla korea has been hacked multiple times as well.
That's good. 'Cause I also remember when Microsoft was distributing Nimda-infected distro CDs and the microsoft.com site itself was slammed by Nimda in September, 2001.
Do a search on the subject and you'll find a lot of us had to spend an awful lot of time analyzing and cleaning up after Microsoft's mess just one week after 9/11. Thanks a lot, pal.
