Ad networks are surreptitiously using ultrasonic communications to jump from device to device. It should come as no surprise that this communications channel can be used to hack devices as well. Powered by WPeMatico
This is exactly the sort of Internet-of-Things attack that has me worried: “IoT Goes Nuclear: Creating a ZigBee Chain Reaction” by Eyal Ronen, Colin OFlynn, Adi Shamir and Achi-Or Weingarten. Abstract: Within the next few years, billions of IoT devices will densely populate our cities. In this paper we describe a new type of threat … Read More “Self-Propagating Smart Light Bulb Worm” »
Interesting research: “Don’t Skype & Type! Acoustic Eavesdropping in Voice-Over-IP“: Abstract: Acoustic emanations of computer keyboards represent a serious privacy issue. As demonstrated in prior work, spectral and temporal properties of keystroke sounds might reveal what a user is typing. However, previous attacks assumed relatively strong adversary models that are not very practical in many … Read More “Eavesdropping on Typing Over Voice-Over-IP” »
Researchers discover a clever attack that bypasses the address space layout randomization (ALSR) on Intel’s CPUs. Here’s the paper. It discusses several possible mitigation techniques. Powered by WPeMatico
This is interesting research: “Keystroke Recognition Using WiFi Signals.” Basically, the user’s hand positions as they type distorts the Wi-Fi signal in predictable ways. Abstract: Keystroke privacy is critical for ensuring the security of computer systems and the privacy of human users as what being typed could be passwords or privacy sensitive information. In this … Read More “Keystroke Recognition from Wi-Fi Distortion” »
Nice attack against electronic safes: Plore used side-channel attacks to pull it off. These are ways of exploiting physical indicators from a cryptographic system to get around its protections. Here, all Plore had to do was monitor power consumption in the case of one safe, and the amount of time operations took in other, and … Read More “Hacking Electronic Safes” »
New research on tracking the location of smart phone users by monitoring power consumption: PowerSpy takes advantage of the fact that a phone’s cellular transmissions use more power to reach a given cell tower the farther it travels from that tower, or when obstacles like buildings or mountains block its signal. That correlation between battery … Read More “Cell Phones Leak Location Information through Power Usage” »
