MS RDP on non-standard port

[James Lay <jlay () slave-tothe-box net>]

I see these scans semi regularly...usually the cookie is sometimes
blank, sometimes not:

alert tcp $EXTERNAL_NET any -> $HOME_NET !3389 (msg:"SCAN MS Terminal
Server taffic on Non-standard Port"; flow:to_server,established;
content:"|03 00 00|"; depth:3; content:"|e0 00 00 00 00 00|"; offset:5;
depth:6; content:"Cookie|3a| mstshash="; pcre:"/Cookie\x3a mstshash=/";
classtype:attempted-recon; sid:xxxxxxxx; rev:1;)
