WEBSITES HAVE A NEW WAY TO SPY ON VISITORS: ANALYZING THEIR SSD ACTIVITY

Summary from the TLDR Dev newsletter

The FROST tracking method allows websites to covertly monitor visitor activity by using JavaScript to analyze the timing of solid-state drive (SSD) interactions, creating a side channel that reveals information about the host system. By processing these timing patterns through a neural network, malicious sites can identify a user's open applications and browser tabs, although the attack's reliance on large storage files makes it detectable.
