A team of researchers at Georgia Tech, the University of Michigan, and Ruhr University Bochum have developed a novel attack called “Hot Pixels,” which can retrieve pixels from the content displayed in the target’s browser and infer the navigation history.
The attack exploits data-dependent computation times on modern system-on-a-chip (SoCs) and graphics processing units (GPUs) and applies them to stealthily extract information from visited web pages on Chrome and Safari, even if with the latest side-channel countermeasures enabled.
