Hi. Anyone notice an increase of TCP Syns to port 11768, and 445 across random internet IPs? I googled the port, and found a similar posting here:

We located the source on our network, updated DATs, and WindowsUpdate hotfixes, but the problem persists.
Okay, it's been a while since this post was made to NANOG, but I just got the answer. Hadas Shany (Internet Gold/AS5486] just sent this to the IL-ops list: ----- In the past few weeks we saw more and more port scanning on 11768 and 15118 (high ports that has no specific use). So, here is the news: http://www.lurhq.com/dipnet.html . Apparently, it's a virus based on the Sasser vulnerability! Sophos agrees: http://www.sophos.com/virusinfo/analyses/trojdipnetb.html ----- I must admit, Joe Stewart (also known as "DA MAN") at lurhq always comes up with the answers. -- Gadi Evron, Information Security Manager, Project Tehila - Israeli Government Internet Security.
