conducting-external-reconnaissance-with-osint

conducting-external-reconnaissance-with-osint is a skill for Claude Code, Codex from andycungkrinx91/konoha. It costs 96 tokens per session (2,690 once invoked), scanned A, a copy of conducting-external-reconnaissance-with-osint, MIT.

A guide to external reconnaissance using OSINT, or open-source intelligence gathered from publicly available information. It maps an organisation's internet-facing footprint without directly interacting with its systems.

In plain words
What is it for?
Use it during an authorised assessment to review DNS, certificate logs, search results, public documents, social media, leaked data, and possible shadow IT.
Why use it?
Public records can reveal domains, certificates, employees, email patterns, exposed credentials, and forgotten assets. Finding this information early helps define a security test and reduce unknown exposure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

conducting-external-reconnaissance-with-osint scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Conducting External Reconnaissance with OSINT

When to Use

  • Performing the initial reconnaissance phase of a penetration test to gather intelligence before active scanning
  • Mapping an organization's external attack surface to identify unknown or shadow IT assets
  • Collecting employee information, email formats, and organizational structure for social engineering campaigns
  • Identifying exposed credentials, leaked data, or sensitive documents published on the internet
  • Scoping the breadth of an organization's digital footprint prior to a red team engagement

Do not use for stalking, harassment, or unauthorized surveillance of individuals. OSINT gathering must be conducted within the scope of an authorized engagement and comply with applicable privacy laws (GDPR, CCPA).

Prerequisites

  • Written authorization to perform reconnaissance against the target organization
  • Dedicated research workstation with a VPN or Tor for anonymized queries when required
  • OSINT framework tools installed: Amass, theHarvester, Shodan CLI, Recon-ng, SpiderFoot
  • API keys for Shodan, Censys, SecurityTrails, Hunter.io, VirusTotal, and GitHub for enhanced results
  • Disposable email accounts for accessing services that require registration during research

Workflow

Step 1: Domain and DNS Enumeration

Enumerate all domains, subdomains, and DNS records associated with the target:

  • Root domain identification: Start with the primary domain and identify all related domains through reverse WHOIS lookups on registrant name, email, and organization using whoxy.com or domaintools.com
  • Subdomain enumeration: Run multiple tools for comprehensive coverage:
    • amass enum -passive -d target.com -o amass_subs.txt for passive subdomain discovery from 40+ data sources
    • subfinder -d target.com -all -o subfinder_subs.txt for fast passive enumeration
    • crt.sh certificate transparency log queries: curl -s "https://crt.sh/?q=%25.target.com&output=json" | jq -r '.[].name_value' | sort -u
  • DNS record analysis: Query for all record types: dig target.com ANY, check for SPF, DKIM, DMARC records that reveal email infrastructure, and enumerate MX records to identify email providers
  • Zone transfer attempt: dig axfr @ns1.target.com target.com to check for misconfigured DNS servers
  • Consolidate results: Merge, deduplicate, and resolve all discovered subdomains to IP addresses. Map IP addresses to ASN and hosting providers.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
