There’s a common misconception about biometrics and cybersecurity, this misconception is that you can’t get infected or compromised just by visiting a site

Spoiler alert: You can.

I built this fingerprint simulator to demostrate to some extent what a malicious website or a rogue ad can gather from an user simply by having them load the page–and what a threat actor can do with that information.

For legal reasons and ethical reasons I had to go from real visitor data to generating a fake visitor every 10 seconds. All of this because this project showcases all the information gathered to all the public, displaying all this information from real users would be a privacy nightmare, moreso considering that I actually check for CVEs (Common Vulnerability and Exposures), and I check their IP against known data leaks.
