New Side-Channel Attack Targets the CPU Ring Bus for the First Time

In a paper published today, a team of academics from the University of Illinois at Urbana-Champaign have published details about a new side-channel attack against the internal architecture of modern CPUs.

Side-channel attacks take place when attackers are able to observe how a system operates —in this case, a computer processor—, and then infer what data the system is processing based on small variations in its parameters.
