The other ICE peer, the STUN server, the TURN server (if any), and the signaling channel are all under the control of the attacker in a worst case scenario (the user being directed to a hostile or hijacked site). The attacker essentially has perfect knowledge; the only thing we can add that the attacker doesn't know is a random number with each packet. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
