From e66ec59fa7a902679619c51294268e853867b9c7 Mon Sep 17 00:00:00 2001 From: martin Date: Fri, 15 May 2026 16:01:15 +0200 Subject: [PATCH] Add github-recon-v3.sh: optimized GitHub OSINT scanner Rewrite of bash/github-recon.sh with focus on robustness, performance and additional OSINT/security coverage. Original script remains untouched. Highlights: - Robust API-error handling, full pagination, retry with backoff - Sensitive-files step: 18 API calls instead of 1800 (user:X filename:Y) - Interactive token setup with gh CLI auto-detect (--setup-token) - New OSINT: public SSH/GPG keys, orgs, activity heatmap with timezone inference, Wayback Machine for deleted/renamed repos - New security: CI/CD workflow YAML scan, internal endpoint detection - Deep scan actually invokes noseyparker/gitleaks/trufflehog - Severity levels (CRITICAL/HIGH/MEDIUM/LOW/INFO), CI-ready exit codes - JSON output additionally to markdown, diff mode for tracking findings over time Adds bash/README.md describing both scripts.
