Hartzbleed is a new side-channel attack that works against a variety of microprocressors. Deducing cryptographic keys by analyzing power consumption has long been an attack, but it’s not generally viable because measuring power consumption is often hard. This new attack measures power consumption by measuring time, making it easier to exploit. The team discovered that … Read More “Hartzbleed: A New Side-Channel Attack” »

Researchers have demonstrated controlling touchscreens at a distance, at least in a laboratory setting: The core idea is to take advantage of the electromagnetic signals to execute basic touch events such as taps and swipes into targeted locations of the touchscreen with the goal of taking over remote control and manipulating the underlying device. The … Read More “Remotely Controlling Touchscreens” »

Rowhammer is an attack technique involving accessing — that’s “hammering” — rows of bits in memory, millions of times per second, with the intent of causing bits in neighboring rows to flip. This is a side-channel attack, and the result can be all sorts of mayhem. Well, there is a new enhancement: All previous Rowhammer … Read More “New Rowhammer Technique” »
