Intel and AMD Hertzbleed CPU Vulnerability Uses Boost Speed to Steal Crypto Keys

(Image credit: Hertzbleed) Intel and researchers from UT Austin, UIUC, and UW published papers today outlining the ‘Hertzbleed‘ chip vulnerability that allows side-channel attacks that can steal secret AES cryptographic keys by observing the CPU’s boost frequency/power mechanisms. According to external researchers, both Intel and AMD CPUs are impacted, but AMD hasn’t issued an advisory…

Intel Hertzbleed CPU Vulnerability Uses Boost Speed to Steal Crypto Keys

(Image credit: Intel) Intel and researchers from UT Austin, UIUC, and UW published papers today outlining the ‘Hertzbleed’ chip vulnerability that allows side-channel attacks that can steal secret AES cryptographic keys by observing the CPU’s boost frequency/power mechanisms. The vulnerability doesn’t impact all cryptographic code, but some mitigation techniques for impacted systems come with as-yet-undefined…
