Researchers Hack IP Video

Man-in-the-middle attacks tamper with video surveillance feeds, eavesdrop on IP video phone conversations

Researchers put a new spin on an old attack at Defcon last week, demonstrating how to execute man-in-the-middle attacks on IP video.

In one attack, researchers from Viper Lab showed how a criminal could tamper with an IP video surveillance system to cover up a crime by replacing the video with another benign clip. In another demo, they eavesdropped on a private IP video call.

IP video -- for videoconferencing, IP TV, video streaming applications, and video surveillance -- is gradually catching on in organizations, the federal government, and even in professional sports arenas like the Dallas Cowboys' new state-of-the-art stadium. But like any IP technology, IP video can be vulnerable to attack if it's not properly locked down. "These attacks are based on ARP poisoning/man-in-the middle. You can do this with email and VoIP -- we're just doing a new twist on an old attack to show people that these vulnerabilities are out there for IP video," says Jason Ostrom, director of Viper Lab, the research arm of Sipera Systems, which sells security products for VoIP and unified communications technologies.

The so-called UCSniff tool performs video eavesdropping, while VideoJak intercepts and replays video. "We used UCSniff to record a 'safe' video stream, then converted it to an AVI file. Then we used the VideoJak tool that also supports man-in-the-middle," he says. VideoJak intercepts the video stream, and replaces it with a malicious or phony video payload.
