Malicious attack uses a computer's internal SATA cables as radio aerials to illicitly broadcast secret information..
One way to protect computer networks from malicious attack is to disconnect them from the internet. This approach, known as air-gapping, creates a physical barrier between the network and the nasty world of malicious attackers beyond.
A SATA cable connects a motherboard data bus to a mass storage device such as a solid-state drive, optical drive or hard disc drive. The cables are a few centimeters long and most operate at a frequency of 6 Gb/sec. He then used a laptop placed about a meter away to monitor transmissions in the 6Ghz band, decoding the word “SECRET” from the illicit broadcasts. “We show that attackers can exploit the SATA cable as an antenna to transfer radio signals in the 6 GHz frequency band,” says Guri.
