Due to the low power of electromagnetic radiation (EMR), EM convert channel has been
widely considered as a short-range attack that can be easily mitigated by shielding. This …

In this paper, first, a broad overview of existing covert channel communication-based
security attacks is provided. Such covert channels establish a communication link between …

As the popularity of graphics processing units (GPUs) grows rapidly in recent years, it
becomes very critical to study and understand the security implications imposed by them. In …

This article presents a new attack allowing attackers to exfiltrate data from isolated, air-
gapped computers via Wi-Fi frequencies. We show that malware in a compromised air …

In this article, we introduce a new covert channel that enables attackers to leak data
acoustically from highly secured, air-gapped and audio-gapped systems. The proposed …

Air-gapped systems are isolated from the Internet due to the sensitive information they
handle. This paper introduces a covert channel attack that leaks sensitive information over …

RAPL (Running Average Power Limit) is a hardware feature introduced by Intel to facilitate
power management. Even though RAPL and its supporting software interfaces can benefit …

Deep neural networks (DNNs) are becoming increasingly popular in real-world applications,
and they are considered valuable assets of enterprises. In recent years, a number of model …

This paper introduces a new type of attack on isolated, air-gapped workstations. Although air-
gap computers have no wireless connectivity, we show that attackers can use the SATA …

Electronic devices generate electromagnetic noise, also known as EM leakage when the
noise leaks information. Many recent research papers exploit the fact that software activity …
