Hot Pixels attacks exploit power management in modern SoC and GPUs to leak data

In context: Dynamic voltage and frequency scaling (DVFS) is a technique adopted by modern CPUs and graphics chips to manage power and speed, adjusting frequency and voltage “on the fly” to reduce energy consumption and heat generation. With a “Hot Pixels” attack, DVFS becomes yet another channel a (very) resourceful attacker could exploit… https://ift.tt/wSB4v2O Read […]
