Overview The Repo Secret Scanner at cybergrind.org/tools/repo-scanner/ scans public GitHub repositories for exposed credentials — AWS keys, GitHub tokens, Slack tokens, Stripe keys, private keys, and more — without ever cloning the repository. It runs entirely on a Cloudflare Worker, reads files directly via the GitHub API, and returns a severity-scored dashboard of findings with matched secrets redacted before they ever leave the scanner. ...
Overview This guide covers the complete deployment of the Repo Secret Scanner from a fresh clone to a live public tool. It assumes you’re deploying into the same stack used for CyberGrind: Hugo + PaperMod on Cloudflare Pages, Cloudflare Workers for serverless backend functions, and GitHub for source control. ...
Overview The Repo Secret Scanner uses three detection tiers: high-confidence prefix-matched patterns (Tier 1), keyword-gated generic patterns (Tier 2), and Shannon entropy analysis for unrecognized secrets (Tier 3). This article documents every pattern in the current ruleset, their sources, their known limitations, and the structural gaps no static scanner can close. ...
CyberGrind is a personal cybersecurity portfolio, threat intelligence platform, and educational resource — all running on free and open source tooling. This article documents how it was built: the design decisions, the architecture, how all the pieces connect, and the gotchas learned along the way. ...
