The script, which BleepingComputer verified through its own testing, also harvests the CPU core count, available memory, screen resolution, time zone, language settings, and battery status. The findings were first published in Fairlinked’s “BrowserGate” report, which claims the script works by attempting to access file resources tied to specific extension IDs, a well-documented technique for detecting whether extensions are installed in Chromium-based browsers. A GitHub repo documented LinkedIn scanning for roughly 2,000 extensions in 2025, while a separate repo from February this year logged approximately 3,000. The current count stands at 6,236.

The Fairlinked report claims that LinkedIn scans more than 200 competing products in total and that the script also checks for language and grammar extensions, tools for tax professionals, and other categories with no obvious connection to LinkedIn's platform.

These data points are commonly used in browser fingerprinting to build unique device profiles, but because LinkedIn accounts are tied to real names, employers,
