From: jeremiah at nur.net (Jeremiah Cornelius) Subject: New msbalster? Interesting phenomenon emerging: We have noticed in our log aggregators that some of the same hosts yesterday that were doing port 135 scans... today seem to be doing some port 1026 scans. This is a listener port for MS Messenger. List follwers will remember that this has been used as an avenue for spammers to send "pop-up" alerts on users desktops. farm9 (the InfoSec group I work for) is keeping an eye on this - we correlate syslog, winlog, IDS and firewall data from a dozen or so enterprises. Has anybody spotted similar activity? It would be interesting to see if this is a new worm iteration. Maybe sombody clever has figured they can deliver MSSBlast.exe or phallus32.exe via Messenger. I have already noticed curious folks that find that they can bind to a shell on 4444, and are now fiddling around here - for a minute or so... ;-) -- Jeremiah Cornelius, CISSP, CCNA, MCSE, Debianaut farm9 Security email: jc@...m9.com - mobile: 415.235.7689 "What would be the use of immortality to a person who cannot use well a half hour?" --Ralph Waldo Emerson
