A new tracking technique named FROST has been revealed, allowing websites to monitor users' solid-state drive (SSD) activity directly from the web browser. According to a report by Wired on June 1, 2026, this method can be easily deployed using standard JavaScript code without requiring the installation of any additional malicious software.
How It Works
The FROST technique works by measuring the unique activity signatures of an SSD during data processing. When a user visits a website, a simple JavaScript script measures response times and SSD performance fluctuations to record data.
Detailed information about FROST reveals that websites can collect data on how and when the SSD operates. The Wired report highlights that this behavior can be executed entirely in the background, leaving users completely unaware that their physical storage device is being monitored.
Why It Matters
For the tech community in Vietnam, the threat of FROST is clear as it bypasses traditional security barriers. This tracking method does not rely on cookies, making it difficult for conventional security tools to fully detect and block it.
Currently, browser developers face a major challenge in patching this vulnerability without compromising the overall performance of JavaScript. Readers are advised to regularly update their browsers to receive timely security patches that protect their devices from the FROST technique.
