So, phones that are pre-rigged to violate “no recording devices allowed” policies can fairly easily be spotted by a supervisory check before they’re allowed into a secure area. Problem was overcome by the discovery that many if not most computer speakers can actally produce so-called ultrasonic sounds, with frequencies high enough (typically 17,000 hertz or above) that few, if any, humans can hear them.Īt the same time, a typical mobile phone microphone can pick up ultrasonic sounds at the other side of the airgap, thus providing a covert audio channel.īut trick was thwarted, at least in part, by the fact that most modern mobile phones or tablets have easily-verified configuration settings to control microphone use. The trouble with soundĮxfiltrating data via a loudspeaker is easy enough (computer modems and acoustic couplers were doing it more than 50 years ago), but there are two problems here: the sounds themselves squawking out of speakers on the trusted side of an airgapped network are a bit of a giveaway, and you need an undetected, unregulated microphone on the untrusted side of the network to pick up the noises and record them surreptitiously.

Or adding meaning to the amound of red tint on the screen from second to second, and many other abstruse airbridging tricks. Or using capacitors on a motherboard to act as tiny stand-in speakers in a computer with its own loudspeaker deliberately removed.

…such as LANTENNA, where innocent-looking network packets on the wires connecting up the trusted side of the network actually produce faint radio waves that can be detected by a collaborator outside the secure lab with an antenna-equipped USB dongle and a software defined radio receiver:Ĭan your computer fan be used to spy on you?

So, if you optimistically assume that alternative networking hardware such as Wi-Fi and Bluetooth are properly controlled, data can only move between “inside” and “outside” in a way that requires active human intervention, and therefore can be robustly regulated, monitored, supervised, signed off, logged, and so on.īut what about a corrupt insider who wants to break the rules and steal protected data in a way that their own managers and security team are unlikely to spot?īen-Gurion University researchers have come up with many weird but workable data exfiltration tricks over the years, along with techniques for detecting and preventing them, often giving them really funky names… The name means literally what it says: there’s no physical connection between the two parts of the network.

So-called airgapped networks are commonly used for tasks such as developing anti-malware software, researching cybersecurity exploits, handling secret or confidential documents safely, and keeping nuclear research facilities free from outside interference.

Mordechai Guri’s paper is entitled GAIROSCOPE: Injecting Data from Air-Gapped Computers to Nearby Gyroscopes, and the title pretty much summarises the story.īy the way, if you’re wondering why the keywords Ben-Gurion University and airgap ring a bell, it’s because academics there routinely have absurd amounts of fun are regular contributors to the field of how to manage data leakage into and out of secure areas. Modern phone gyroscopes don’t have spinning flywheels housed in gimbals, like the balancing gyroscope toys you may have seen or even owned as a youngster, but are based on etched silicon nanostructures that detect motion and movement through the earth’s magnetic field. …to the point that the resonance effects produced enough vibration to crash the disk, which crashed the driver, which crashed Windows.Īt around the same time that the Rhythm Nation story broke, a researcher at Ben-Gurion University of the Negev in Israel published a research paper about resonance problems in mobile phone gyroscopes.

In that “exploit”, something about the beat and mix of frequencies in the song is alleged to have troubled the disk drives in a certain vendor’s Windows laptops, matching the natural vibrational frequencies of the old-school hard disks… That story was publicised only recently, as a bit of weird historical fun, and with an equal sense of fun, MITRE assigned it an official CVE bug number (confusingly, however, with a 2022 datestamp, because that’s when it first became known). On Monday, we wrote about Janet Jackson’s 1989 song Rhythm Nation, and how it inadvertently turned into a proof-of-concept for a Windows-crashing exploit that was reported way back in 2005.

The specialist subject that suddenly popped up twice this week is: resonance. Cybersecurity stories are like buses: the one you’re waiting for doesn’t come along for ages, then two arrive at once.
