Hertzbleed is a new side-channel attack that can recover sensitive information from a targeted system by applying CPU timing. The post Hertzbleed exposes computers’ secret whispers appeared first on Malwarebytes Labs.
A novel timing attack allows remote attackers with low privileges to infer sensitive information by observing power-throttling changes in the CPU.
A newly discovered security vulnerability in modern Intel and AMD processors could let remote attackers steal encryption keys via a power side channel attack. Dubbed Hertzbleed by a group of researchers from the University of Texas, University of Illinois Urbana-Champaign, and the University of Washington, the issue is rooted in dynamic voltage and frequency scaling (DVFS), power and thermal
