Snort doesn't detect W32/Opaserv.worm attack

Hi,

A variant of this worm (INSTIT.BAT) was discovered
recently. On NAI AVERT web page, they give infection mode.
The worm use NetBIOS for NT traffic (UDP port 137).

The default netbios.rules check NetBIOS traffic (TCP
port 139). Could anyone have rules to detect the activity
of this worm ?

I use MDK 8.2 (kernel 2.4.18) and snort 1.8.4.

Regards,

JO
