I came in to work to upload last night’s writing, to find the Internet in the throes of a major “worm” attack. This one affects systems running Microsoft’s SQL Server 2000 software, which can be hijacked through a known security hole. The hole was fixed six months ago, but the patch has clearly not been applied worldwide. It’s possible that the people behind the worm didn’t see the opportunity until the problem was publicized – there’s a lesson in there somewhere, though I have no idea what it is. Things have calmed down somewhat, since I can get through to post this, but I still see some odd browsing failures.
