RE: MS-SQL Worm Signature

["Frank Reid" <fcreid () ourcorner org>]

I found this one on Symantec's ManHunt at:

http://securityresponse.symantec.com/avcenter/venc/data/w32.sqlexp.worm.
html#technicaldetails

alert udp $EXTERNAL_NET any -> $HOME_NET 1434 (msg:"W32.SQLEXP.Worm
propagation"; content:"|68 2E 64 6C 6C 68 65 6C 33 32 68 6B 65 72 6E|";
content:"|04|"; offset:0; depth:1;)

It seems to work perfectly as a Snort rule... is this just coincidence
that they used the same syntax?

Frank

This one is alerting as I write this email:

alert udp $EXTERNAL_NET any -> $HOME_NET 1434 (msg:"MS-SQL Slammer Worm
Activity"; 
content:"|04 01 01 01 01 01 01 01|"; classtype:bad-unknown; sid:9994;
rev:1;)
