[Snort-sigs] VNC Failed Login

Subject: [Snort-sigs] VNC Failed Login
Date: Thu, 2 Sep 2004 14:26:19 -0400
Saw a warning on isc.sans.org about brute force VNC login attempts and
couldn't really find any rules to detect it, so I threw together this
one:

alert tcp $HOME_NET 5900 -> $EXTERNAL_NET any (msg:"VNC Failed Login";
flow:to_client,established; content:"|00 00 00 00 00 01 00 00 00 16|";
content:"Authentication|20|failure"; classtype:unsuccessful-user;
sid:1000001; rev:1;)
