- Implement and evaluate common challenge and detection paths
Prerequisites
- Sections 1-3 completed
- Basic Playwright or Puppeteer familiarity
Section Breakdown
Lecture 16
Introduction to Headless Detection
Frame why headless detection is partly about environment integrity and partly about execution behavior.
Lecture 17
Puppeteer & Playwright Detection Techniques
Map the specific leaks and heuristics defenders use against the most common automation frameworks.
Lecture 18
Anti-Detect Browsers & Evasion
Assess how anti-detect stacks patch fingerprints, where they still fail, and what defenders can do about it.
Lecture 19
JavaScript Challenges — How They Work & Why Bots Fail
Explain challenge orchestration, execution environments, and the fragile assumptions inside many automation setups.
Lecture 20
JS Challenge Evasion — Headless Execution & Bypass Techniques
Analyze how adversaries replay, instrument, or relocate challenge execution to preserve throughput.
Lecture 21
Automated Browser Detection Script
Draft a simple but practical browser challenge and inspect what it reveals in controlled runs.
Quiz
Headless Browser Quiz
Test recognition of automation signals, challenge tradeoffs, and realistic evasive responses.
