A two-stage attack could allow spies to sneak secrets out of the most sensitive buildings, even when the targeted computer system is not connected to any network, researchers from Ben-Gurion University of the Negev in Israel stated in an academic paper describing the refinement of an existing attack.

The technique, called AirHopper, assumes that an attacker has already compromised the targeted system and desires to occasionally sneak out sensitive or classified data. Known as exfiltration, such occasional communication is difficult to maintain, because government technologists frequently separate the most sensitive systems from the public Internet for security. Known as an air gap, such a defensive measure makes it much more difficult for attackers to compromise systems or communicate with infected systems.

I doubt the average PC user will ever have to worry about this,

At 60 bytes per second with a 1 to 7 meter range... the only use is high level hacking on corporate/government targets. Wouldn't be worth the wait to nick your nudie pics.

I'm glad I live on the side of a mountain. I'll never get "AirHopped".

The title of this threat "Researchers bridge air gap by turning monitors into FM radios" is misleading,

it should be "Researchers bridge air gap by turning monitors into FM Transmitters"

Is this really news? I have never worked with anything secret enough to worry about that kind of leak, but I remember reading about it quite a few years ago. Somebody was claiming to have a new way to prevent people from reading what was on the monitor. I said something about it to a friend of mine and he had worked with the other system, the previous state of the art that they were comparing their new development to. Their claim was that they had something almost as good as the previous technology at lower cost. The problem they were working on was not that anyone would intentionally transmit data via the monitor but that the normal operation of the monitor caused emission of a signal that could be received outside the building.
