Researchers at Ben Gurion University’s Cyber Security Research Center have presented an attack that could compromise the security of Faraday cages, Motherboard reports. While Faraday cages have been considered effective, the researchers intended to prove that a motivated attacker could bypass its protections. Researchers presented two papers detailing how attackers can leak data from air-gapped computers to nearby smartphones by manipulating the magnetic signals using what they call MAGNETO and ODINI. In an email to Motherboard, Mordechai Guri, head of research and development at the center, said, “Faraday cages are known for years as good security for electromagnetic covert channels,” adding, “Here we want to show that they are not hermetic and can be bypassed by a motivated attacker.”
