Hertzbleed Attack Impacting Intel & AMD CPUs | Security Insights By PurpleSec

In June 2022, a group of researchers from the University of Texas, the University of Illinois Urbana-Champaign, and the University of Washington, have published an article on their website about a new attack they developed called Hertzbleed.

This attack allows attackers to detect variations in the frequency of CPU using something called Dynamic voltage and frequency scaling or DVFS in short, and steal entire cryptographic keys in that way.

Intel’s security advisory states that all Intel processors are affected. We …
