Subdomain Takeover Checker

Detect dangling DNS records that could be hijacked. Checks if subdomains point to services that might be unclaimed.

Quick Start

# Check a list of subdomains
bash {baseDir}/scripts/check-takeover.sh -l subdomains.txt

# Check single subdomain
bash {baseDir}/scripts/check-takeover.sh -d sub.example.com

# Passive DNS only (no HTTP verification)
bash {baseDir}/scripts/check-takeover.sh -l subdomains.txt --passive
