Browser SSD side channel may reveal user activity
An article published on May 29, 2026 reports that SSD latency measurements through the browser's Origin Private File System can identify visited sites and detect launched desktop applications.

What happened and what to do
The article, published on May 29, 2026, describes measuring SSD latency through the browser's Origin Private File System in a regular tab. According to the text, the method identified visited sites with 88% accuracy and detected launched desktop applications with 95% accuracy, without requiring permissions or native code. It uses storage contention to infer activity across applications.
A company can assess whether its browsers and workstations are exposed to this kind of inference and review security controls, usage policies, and updates. Practical work could include controlled testing, monitoring relevant signals, and recommendations to reduce exposure; the case does not inherently call for an AI solution.
How the consultancy can help
Wendelmaques can diagnose exposure across browsers and workstations, define a testing scope, and implement security and monitoring improvements. Ongoing operation can be scoped to the company's environment and needs.
