I'm reading the Slashdot article [1] about Curious Yellow [2], a theoretical superworm, when I come across this post [3] about an increase in NetBIOS probes. Curious, I decide to check the firewall here at the Facility in the Middle of Nowhere to see just how bad it is.
From September 29^th starting at 6:11 am, to now, at 7:06 pm, 92% of all rejected packets have been NetBIOS probes (14,379 out of 15,563); about one every three minutes or so. Not quite twice a day as the post says, but still, not a good thing.
Reading further [4], it may be due to the Opaserv worm [5].
Wonderful.
