Bugnets Could Spy on You via Mobile Devices
Imagine sitting in a café and discussing the details of a business proposal with a potential client. Neither you nor the client has a laptop; you're just two people having a conversation. But unbeknownst to you, someone half a world away is listening to every word you say. Later, as you leave, you receive a text message referring to the proposal and demanding money in exchange for silence.
Recent research from two universities suggests that such a remote-eavesdropping scenario may soon be possible.
According to George Mason University researchers Ryan Farley and Xinyuan Wang, cell phones make excellent surveillance devices for remote snoops. In a paper, Farley and Wang discuss a "modernized mic hijacker" [PDF] that an attacker could control over what they call a "roving bugnet." The eavesdropper would use a piece of malware called a "bugbot" to listen in on in-person interactions via a nearby smartphone or laptop. Such attacks would be more likely to target specific people (a wayward spouse, say) than to play a role in widespread attacks on the general public.
