FROST Attack Uses SSD Timing and Neural Nets to Track Browser Tabs
June 2, 2026
JavaScript-based side-channel attack infers open applications and browser tabs by measuring SSD read/write timing patterns, then classifying them with a neural network. The method works despite browser sandboxing and requires no special permissions, posing a fingerprinting risk across modern hardware.
HOW THIS AFFECTS YOU
●
builderYou need to assess whether your web apps or browser-based AI tools expose timing surfaces that could leak user session data via this vector.
●
policyWorth watching because this is a passive, hard-to-consent-to tracking mechanism that bypasses existing browser privacy controls, with implications for GDPR and ePrivacy compliance.
