[Intrusions] Port Scanning on 1026 & 1027

[Leeuwen, Allan van]

There was an old vulnerability in the messenger service (allowing code
execution under SYSTEM privileges).
That was about 2 years ago though .. If you had not installed that patch
yet .. You would have different problems.

Just got back from vacation ...

A colleague reports a Windows worm on August 25th identified as
"Hacktool" by Symantec

My network logs (300 bytes/packets or so) include a messenger packet
around the time of the worm infection. This could of course be a total
coincidence ... there is an ICMP packet saying the port was closed.

"SYSTEM ALERT .. STOP! WINDOWS REQUIRES IMMEDIATE
ATTENTION  Windows has found 47 CRITICAL SYSTEM ERRORS! To fix the
erro....."

Seeing as this arrived at 2am local I don't think a user would have
clicked "OK"

Is there anything exploiting these ports now, apart from just spam ?
