Tricking the user to access history using CSS and captchas

Tricking the user to access history using CSS and captchas launched on June 9, 2014 with 140 votes, #95 of 1,531 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 12 years on.

In plain words

This project demonstrates a security vulnerability where CSS and CAPTCHAs can be manipulated to trick users into revealing their browser history. Created in 2014, it serves as an educational tool for understanding web security risks and how seemingly innocent interface elements can be exploited. The project is aimed at security researchers and developers learning about client-side vulnerabilities and the importance of proper input validation and user awareness in web applications.

  • Replace CAPTCHAs with WebAuthn passkeys for bot prevention2024 · github.com · ▲71

    I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly. What makes Nocaptcha different: - Uses WebAuthn standard instead of puzzle-solving - No need for users to remember passwords or solve puzzles - Open source Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case. Looking for feedback particularly on: 1. Integration experience 2. User experience compared to traditional CAPTCHAs
