RAM Signals Expose Air-Gapped Networks to Attacks

RAM-Based Radio Signal Attack Allows Attackers to Exfiltrate Data Prajeet Nair (@prajeetspeaks) • September 10, 2024

A novel side-channel attack exploits radio signals emitted by random access memory in air-gapped computers, presenting a new threat to highly secure networks.

Researchers from Ben-Gurion University of the Negev introduced a new technique called the RAMBO, for RAM-Based Radio Signals attack, which allows attackers to exfiltrate data from air-gapped systems using radio frequencies generated by RAM.

Air-gapped networks are physically isolated from the internet, with no wired or wireless communication channels available, making them common in sensitive environments such as military installations and critical infrastructure.

Leader researcher Mordechai Guri in newly published research demonstrated that even those environments are vulnerable to sophisticated attacks.

"Attackers can turn the very hardware inside these ...
