Cybersecurity professionals often rely on lightweight tools during the early stages of web reconnaissance.
One underrated but powerful tool is the Check My Links browser extension.
🔍 What it does:
It scans all hyperlinks on a webpage and highlights:
- Broken links (404 errors)
- Redirect chains (301/302)
- Valid vs invalid URLs
- External link structures
🛡️ Why it matters in cybersecurity:
In real-world OSINT and penetration testing, broken or outdated links often reveal:
- Forgotten subdomains
- Legacy web applications
- Abandoned staging environments
- Old admin panels still partially accessible
- Shadow IT assets
These elements significantly expand the attack surface of an organization.
🚀 Use cases:
- Bug bounty hunting
- Web application reconnaissance
- OSINT investigations
- Security audits
- Attack surface mapping
💡 Pro insight:
Attackers rarely start with exploits. They start with discovery. Tools like Check My Links help map hidden infrastructure faster.
