Eavesdropping on Typing Over Voice-Over-IP

Posted on by

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 real-world settings. Such strong models… Continue reading Eavesdropping on Typing Over Voice-Over-IP→

Keystroke Recognition from Wi-Fi Distortion

Posted on by

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 paper, we show for the… Continue reading Keystroke Recognition from Wi-Fi Distortion→

Hacking Electronic Safes

Posted on by

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 voila, he was able to… Continue reading Hacking Electronic Safes→
