SQL Server Worm?

[Dave Stewart <dbs () dbscom com>]

I can't say for certain, not having taken an exhaustive look (it is, after 
all, almost 3 in the morning out here on the right coast), but on the one 
MS SQL server here, there do not appear to be new files installed, and 
after rebooting, the server is *not* spewing forth traffic as it was earlier.

I don't see any new stored procedures at a glance, so perhaps rebooting 
resolves the issue.

Of course:

access-list xxx deny udp any any eq 1434

helps, as well, in my case... lotta incoming hits to 1434... but none 
outbound in the past 20 minutes
