BrowserGate: LinkedIn Illegally Searching Your Browser Extensions
🚨 Major Privacy Scandal: Fairlinked e.V. reveals LinkedIn is running one of the largest corporate espionage operations in modern history - scanning users' computers for installed software, browser extensions, and competitor tools.
What They Found
Mass Breach of Personal Data
LinkedIn's scan reveals:
- Religious beliefs and political opinions
- Disabilities and health conditions
- Job search activity (including 509 job search tools)
- Practicing Muslims (via religious extensions)
- Political orientation (via political extensions)
- Neurodivergent users (via specialized extensions)
Under EU law, this data is not regulated - it's prohibited. LinkedIn has no consent, no disclosure, and no legal basis.
Corporate Espionage & Trade Secret Theft
- Scans for 200+ products that compete with LinkedIn's sales tools
- Targets Apollo, Lusha, ZoomInfo, and hundreds more
- Maps which companies use which competitor products
- Extracts customer lists from users' browsers without consent
- Has sent enforcement threats to users of third-party tools using data from this covert scanning
Deceiving EU Regulators
In 2023, the EU designated LinkedIn as a regulated gatekeeper under the Digital Markets Act and ordered it to open its platform.
- LinkedIn published two restricted APIs handling ~0.07 calls per second
- Meanwhile, LinkedIn operates internal API "Voyager" at 163,000 calls per second
- In Microsoft's 249-page compliance report, "API" appears 533 times, "Voyager" 0 times
- Surveillance list grew from ~461 products in 2024 to 6,000+ by February 2026
Data Shared with Third Parties
- Loads invisible tracking element from HUMAN Security (formerly PerimeterX)
- Zero-pixel wide tracking hidden off-screen
- Sets cookies without user knowledge
- Fingerprinting script from LinkedIn's own servers
- Third script from Google executes silently on every page load
- All encrypted and undisclosed
Legal Implications
This is illegal and potentially a criminal offense in every jurisdiction examined. The investigation is being conducted by Fairlinked e.V., an association of commercial LinkedIn users.
