SATAn Turns Hard Drive Cable Into Antenna To Defeat Air-Gapped Security

It looks like [Mordechai Guri]’s lab at Ben-Gurion College is the put in which air-gapped desktops go to die, or at least to give up their strategies. And this hack making use of a computer’s SATA cable as an antenna to exfiltrate facts is an additional illustration of just how quite a few side-channel attacks the usual Personal computer would make available.

The exploit, deliciously designated “SATAn,” relies on the truth that the SATA 3. interface utilized in numerous personal computers has a bandwidth of 6. Gb/s, which means that manipulating the computer’s IO would make it feasible to transmit data from an air-gapped device at all over 6 GHz. It’s a complicated exploit, of class, and requires putting a transmitting application on the goal machine making use of the normal approaches, these types of as phishing or zero-day exploits. When in location, the transmitting software utilizes a mixture of browse and produce functions on the SATA disk to crank out RF indicators that encode the info to be exfiltrated, with the facts lines inside the SATA cable acting as antennae.

SATAn is proven in motion in the online video down below. It will take a though to transmit just a handful of bytes of data, and the array is considerably less than a meter, but that could be enough for the exploit to be successful. The exam set up makes use of an SDR — specifically, an ADALM PLUTO — and a notebook, but you can effortlessly think about a significantly lesser package deal getting crafted for a stealthy walk-by design attack. [Mordechai] also offers a probable countermeasure for SATAn, which generally thrashes the challenging generate to deliver RF sound to mask any produced alerts.

When probably limited in its sensible apps, SATAn is an interesting aspect-channel attack to incorporate to [Dr. Guri]’s listing of exploits. From optical exfiltration applying security cameras to turning electrical power supplies into speakers, the vulnerabilities just continue to keep piling up.

Many thanks to [chuckt] for the suggestion.
