Simulated Attack Case Study: Archive.today CAPTCHA Pattern
Simulated Repeated Request Attack — Redesigned Demo & Analysis
Detailed, safe simulation and step-by-step explanation of the reported archive.today CAPTCHA pattern. Evidence and community sources linked below; allegations are presented as reported.
What this page does
This post reconstructs and explains the reported client-side pattern: a timer that repeatedly builds and issues unique request URLs (example: https://gyrovague.com/?s=random). The demo below visualizes the traffic effect and produces a safe, downloadable simulation log for demonstration purposes only.
Simulation of Repeated Request Attack (safe)
No network requests are performed. The log shows simulated URLs in the format observed in the reporting.
Long-form explanation — technical & operational impact
The reported client-side pattern is deceptively simple: a `setInterval` timer combined with a request builder. Each iteration creates a unique query string — for example, a small random token — so typical caching is avoided. When a single browser issues multiple requests per second, the server must compute responses for each request. Multiply this behavior by many simultaneous visitors and resource consumption rises quickly.
Operational effects observed or reported by site operators include increased CPU usage, saturated database query capacity, exhausted I/O, and ultimately denial of service for normal users. Small blogs often lack the traffic engineering resources or CDNs to absorb such sustained client-side floods, making the effect disproportionately harmful to independent publishers.
