Summary
These files provide a comprehensive technical breakdown of Project Hypersurface, an implementation of the attack that exploits hardware-level contention in SSD controller queues to bypass browser isolation. The available materials include geometric simulations that model signal intersections in shared physical space, a threat classification matrix comparing storage vulnerabilities by complexity and severity, and comparative metrics for various physical side-channels such as acoustic and electromagnetic emissions. Additionally, the documentation details the attack's potential as a covert signaling channel with specific data-transmission thresholds and provides a live contention monitoring simulation that uses neural networks to fingerprint user activity. To illustrate the exploit's efficacy, the file also outlines diagnostic modules for bypassing system defenses, specifically targeting timer quantization through security headers and the OS page cache via massive OPFS memory-thrashing operations. These technical analyses are accompanied by numerous class and sequence diagrams, ASCII models, and Python scripts designed to visualize the underlying hardware interactions.
