Detecting Forged Browser Fingerprints For Bot Detection, Lessons From LinkedIn
Security Boulevard, Friday, January 16th, 2026
In my previous post, I showed how LinkedIn detects browser extensions as part of its client-side fingerprinting strategy. That post did surprisingly well, maybe because people enjoy reading about LinkedIn on LinkedIn.
So I decided to take another look at their fingerprinting script.
This time, I want to focus on a different set of signals they use, ones specifically designed to detect forged or inconsistent browser fingerprints.
