Dan Kaminsky will share details of this technique, which will eventually be rolled into a free software tool, today at the Black Hat USA security conference in Las Vegas. The software can tell whether computers are treating some types of TCP/IP traffic better than others -- dropping data that is being used in voice-over-IP (VoIP) calls or treating encrypted data as second-class.
