Correction/update to my earlier post: It seems to be scanning random chunks of addresses, not /16's, see below for a listing of targets probed over a 75 second period. Notice how it starts off with incrementing the host of a /24 then jumps to a different /8 and increments only the first octet. Yesterday night's NAV signatures detect it as W32.Opaserv.Worm. A view of the properties of the file show a C time of this past Sat night (9/28 19:32 PST), and an M time of 1/1/70.
What is the relationship between the IP this scanning host had, and the IP blocks it started scanning, or the IP blocks it scanned at all? Any?
