Detecting Evasive Malware on IoT Devices Using Electromagnetic Emanations
Cybersecurity researchers have proposed a novel approach that leverages electromagnetic field emanations from the Internet of Things (IoT) devices as a side-channel to glean precise knowledge about the different kinds of malware targeting the embedded systems, even in scenarios where obfuscation techniques have been applied to hinder analysis. With the rapid adoption of IoT … [Read more...] about Detecting Evasive Malware on IoT Devices Using Electromagnetic Emanations
Eavesdropping Bugs in MediaTek Chips Affect 37% of All Smartphones and IoT Globally
Multiple security weaknesses have been disclosed in MediaTek system-on-chips (SoCs) that could have enabled a threat actor to elevate privileges and execute arbitrary code in the firmware of the audio processor, effectively allowing the attackers to carry out a "massive eavesdrop campaign" without the users' knowledge. The discovery of the flaws is the result of … [Read more...] about Eavesdropping Bugs in MediaTek Chips Affect 37% of All Smartphones and IoT Globally
