Cross-Scale Persistence Analysis of EM Side-Channels for Reference-Free Detection of Always-On Hardware Trojans

Always-on hardware Trojans pose a serious challenge to integrated circuit trust, as they remain active during normal operation and are difficult to detect in post-deployment settings without trusted golden references. This paper presents a reference-free detection framework based on cross-scale...

Reference-Free EM Validation Flow for Detecting Triggered Hardware Trojans

Hardware Trojans HTs threaten the trust and reliability of integrated circuits ICs, particularly when triggered HTs remain dormant during standard testing and activate only under rare conditions. Existing electromagnetic EM side-channel-based detection techniques often rely on golden references o...

COVID-bit: New COVert Channel to Exfiltrate Data from Air-Gapped Computers

An unconventional data exfiltration method leverages a previously undocumented covert channel to leak sensitive information from air-gapped systems. "The information emanates from the air-gapped computer over the air to a distance of 2 m and more and can be picked up by a nearby insider or spy wi...

Advisory ROSA-SA-2021-1870

Software: libgcrypt 1.5.3 OS: Cobalt 7.9 CVE-ID: CVE-2014-5270 CVE-Crit: CRITICAL CVE-DESC: Libgcrypt before 1.5.4, used in GnuPG and other products, incorrectly performs ciphertext normalization and ciphertext randomization, making it easier for physically proximate attackers to conduct key...

Exfiltrating Data from Air-Gapped Computers via Wi-Fi Signals (Without Wi-Fi Hardware)

A security researcher has demonstrated that sensitive data could be exfiltrated from air-gapped computers via a novel technique that leverages Wi-Fi signals as a covert channel—surprisingly, without requiring the presence of Wi-Fi hardware on the targeted systems. Dubbed "AIR-FI," the attack hing...

Hackers Can Now Steal Data Even From Faraday Cage Air-Gapped Computers

A team of security researchers—which majorly focuses on finding clever ways to get into air-gapped computers by exploiting little-noticed emissions of a computer's components like light, sound and heat—have published another research showcasing that they can steal data not only from an air gap...

CIA Has Been Hacking iPhone and iPad Encryption Security

Security researchers at the Central Intelligence Agency CIA have worked for almost a decade to target security keys used to encrypt data stored on Apple devices in order to break the system. Citing the top-secret documents obtained from NSA whistleblower Edward Snowden, The Intercept blog reporte...
