Individual skill
exploiting-broken-link-hijacking
Discovers and exploits broken link hijacking by spidering a site (Burp Suite Spider, Scrapy, curl scraping), extracting referenced external scripts/domains, and checking DNS/CNAME records and domain registration status for expired or unclaimed resources an attacker could register. Use for subdomain takeover testing, supply-chain review of third-party scripts, or bug bounty hunting for hijackable external resources.

# Exploiting Broken Link Hijacking
## When to Use
- When auditing web applications for references to expired or unclaimed external resources
- During supply chain security assessments of third-party script and resource dependencies
- When testing for subdomain takeover opportunities via dangling CNAME records
- During bug bounty hunting for broken link hijacking vulnerabilities
- When assessing the security of external resource dependencies in production applications
## Prerequisites
- Web crawler or spider for discovering all external links (Burp Suite Spider, Scrapy)
- DNS lookup tools for checking CNAME records and domain availability
- Domain registrar access for claiming expired domains (as proof of concept)
- Understanding of CDN and cloud service provisioning (S3, Azure Blob, GitHub Pages)
