Like this?

alert tcp $HOME_NET any -> $HOME_NET 9996 ( msg: "Sasser Transfer (internal) up.exe"; content: "|5F75702E657865|"; 
depth: 250; flags: A+; classtype: attempted-admin; resp:rst_snd,rst_rcv; sid: 1013252; rev: 1;)
alert tcp $HOME_NET any -> $HOME_NET 5554 ( msg: "Sasser Transfer FTP"; content: "RETR"; flow:to_server,established; 
flags:A+; classtype: attempted-admin; resp:rst_snd,rst_rcv; sid: 1013253; rev: 1;)

Possibly made the difference and kept one of our routers up during
that particular incident, but I can't say for definite - too many
other variables.

(someone else's sig - can't remember who, but thank you)
