Leaking Secrets from Air-Gap Computers by Spelling Radio Signals from RAM (2024)
Air-gapped systems are physically separated from external networks, including the Internet. This isolation is achieved by keeping the air-gap computers disconnected from wired or wireless networks, preventing direct or remote communication with other devices or networks. Air-gap measures may be used in sensitive environments where security and isolation are critical to prevent private and confidential information leakage. In this paper, we present an attack allowing adversaries to leak…
The article discusses a method to leak secrets from air-gap computers by using radio signals from RAM, according to a 2024 report.
A method exists to extract data from air-gapped computers using radio signals.
The technique involves transmitting data through RAM as radio signals.
The research was published in 2024 and highlights a new cybersecurity risk.
