Reading the Street: Recon Without the Noise
A practical walkthrough of passive reconnaissance — OSINT habits that keep you quiet and effective before you ever touch a target.
Methodology
Start quiet. Most of the signal you need is already public.
Recon is less about exotic tooling and more about disciplined reading: DNS history, certificate transparency, exposed documents, job posts that leak stack choices, and social footprints that map trust relationships.
A lightweight checklist
Enumerate domains and subdomains from CT logs. Note email patterns. Capture technology fingerprints from public headers and error pages. Document everything — memory is a liability.
# Example: certificate transparency search
curl -s 'https://crt.sh/?q=%25.example.com&output=json' | jq '.[].name_value' | sort -u
Treat every finding as a hypothesis, not a conclusion. The street rewards patience more than aggression.
