LinkedIn's Hidden Browser Surveillance Exposes User Privacy at Scale

LinkedIn is leveraging a covert browser extension scanning infrastructure—built over nearly a decade—to silently collect software inventory data linked to verified professional identities. By combining extension fingerprints with known employer information and personal profiles, the company gains detailed insights into users' private behaviors, job search activity, political views, and disabilities without explicit consent. This surveillance mechanism transforms LinkedIn from a professional network into a detailed personal intelligence platform, raising critical questions about consent, privacy rights, and the limits of corporate data collection.
