TLS-Based Recon for Attack Surface

Here's a fast and effective recon flow to find and scan hidden assets using TLS certificate metadata and Shodan dorking via Nuclei’s built-in Uncover engine.

Step 1: Find subdomains with subfinder and use tlsx to extract TLS certificate metadata:

subfinder -d tesla.com | tlsx -nc -silent -so | awk '{for(i=2; i<=NF; i++) printf "%s ", $i; print ""}'| tr -d '[],' | sort -uf

📌 This gives you organization names from TLS certificates:

- Tesla Motors Inc.
- Microsoft Corporation
- Akamai Technologies Inc.

Step 2: Use Nuclei's Uncover engine to automatically pull targets from Shodan using a dork with org name, and scan them:

export SHODAN_API_KEY=your_key_here && \

nuclei -rl 300 -nc -uc -ue -ul 10000 -uq 'org:"Tesla Motors Inc"' -silent
