Security assessment skill for reconnaissance, endpoint/service enumeration, and attack-surface mapping. Use when prompts include recon, enumerate, map endpoints, discover assets, inventory interfaces, fingerprint technologies, or identify control-plane surfaces. Do not use when the request is exploit development, payload execution, or final report writing only.
Comprehensive OSINT methodology skill for offensive security, red team intelligence gathering, and bug bounty reconnaissance. Covers domain recon, email harvesting, social media profiling, GitHub/code leaks, Shodan/Censys enumeration, breach data lookup, employee profiling, infrastructure mapping, cryptocurrency tracing, geospatial intelligence, and AI-assisted analysis workflows. Use when performing reconnaissance against a target domain or organization, investigating a person or entity, tracing cryptocurrency flows, geolocating images or events, or building an attack-surface map.
Comprehensive OSINT methodology for external red-team operations and authorized attack-surface assessments. Covers the 5-stage recon pipeline (seed discovery, asset expansion, enrichment, exposure analysis, reporting), asset-graph discipline with 29 asset types, severity rubric (CRITICAL/HIGH/MEDIUM/LOW/INFO), confidence upgrade workflows, time budgeting, asset-level triage rules, scale-based tactics, identity-fabric mapping (Entra/Okta/ADFS/Google/SAML/M365 Teams+SharePoint+OAuth), API and auth-map methodology, JavaScript deep analysis, mobile attack surface, cloud attack surface, breach×identity correlation, detectability tagging, detection-aware probing (back-off, persona rotation), read-only validator discipline, WAF/CDN bypass + origin discovery, vulnerability prioritization (CVE/EPSS/KEV), phishing infrastructure planning + pretext development, bug bounty submission templates, client deliverable templates with risk translation, threat-actor investigation (incl. RU/CN pivots), cryptocurrency tracing, image/video forensics, chronolocation. Use when planning or executing reconnaissance against authorized targets, mapping an organization's external attack surface, investigating a person/entity, tracing crypto flows, geolocating media, or performing attribution work.
End-to-end passive reconnaissance for a domain, website or IP — builds an asset inventory covering registration, DNS, subdomains, infrastructure, tech stack, history and ownership without sending a single packet to the target. Use when asked to research or profile a domain or website, map what an organisation runs, or investigate a suspicious site without alerting its operator. Applies to vendor and third-party risk assessment, attack-surface review, M&A technical diligence, phishing and fraud-site investigation, and pre-engagement scoping.

Entry point for open-source intelligence, investigation and verification work. Routes any identifier — a name, phone number, email address, username, domain, company, photo, crypto address, tail number or IMO — to the right investigation workflow, after setting an authorised scope. Use when asked to investigate, research, verify, vet, check out, look up, background-check, trace, attribute or find someone or something; when a request involves due diligence, KYC or KYB, counterparty or vendor risk, sanctions and PEP screening, AML, fraud, business email compromise, verifying a supplier before payment, recruitment or marketplace scams, insider threat, executive protection, attack-surface review, journalism or fact-checking; or when someone asks "who is this", "who owns this", "is this real", "where did this come from" or "where do I start".

Guides security assessment of embedded and cyber-physical systems on hardware-in-the-loop (HIL) test benches—bench setup, ECU/ECM or PLC targets, bus interfaces (CAN/CAN-FD, LIN, automotive Ethernet, Modbus at high level), fault injection and stimulus design, simulated plant/environment integration, attack-surface monitoring on real hardware, reproducible test cases, lab safety interlocks, and evidence capture for firmware and vehicle security teams. Use for HIL security testing, ECU security assessment, CAN bus security, PLC HIL test, fault injection lab, embedded hardware security—not web/API pentest (web-pentester), network-only pentest (network-pentester), malware/binary RE only (reverse-engineer), SOC operations (soc-analyst), AI red team (ai-redteam), classified ISSO paperwork (information-systems-security-officer-classified-specialist), or pure software CI without hardware (build-validator).
Find internet-exposed hosts, ports, services and devices using third-party internet-scan data instead of touching the target. Covers Shodan and Censys query syntax, service banners, favicon-hash and TLS-certificate pivots, origin-IP discovery behind Cloudflare or a CDN, and exposed databases, dashboards, cameras and ICS devices. Use when asked what a company has exposed to the internet, to check open ports on an IP or netblock, or to write a Shodan filter query. Applies to external attack-surface management, third-party and vendor security review, M&A technical diligence, and pre-engagement reconnaissance. Reference at useosint.com/skills/find-exposed-servers.
Find internet-exposed hosts, services, and devices from third-party scan data. Use when searching Shodan or Censys, finding open ports and banners, identifying an IP's tech stack, or discovering exposed databases, cameras, or industrial devices — without scanning the target yourself.
Passive reconnaissance workflow for a domain, website, or IP — maps DNS, subdomains, infrastructure, tech stack, history, and ownership without touching the target.
Web2 recon pipeline — subdomain enumeration (subfinder, Chaos API, assetfinder), live host discovery (dnsx, httpx), URL crawling (katana, waybackurls, gau), directory fuzzing (ffuf), JS analysis (LinkFinder, SecretFinder), continuous monitoring (new subdomain alerts, JS change detection, GitHub commit watch). Use when starting recon on any web2 target or when asked about asset discovery, subdomain enum, or attack surface mapping.
Advanced vulnerability analysis principles. OWASP 2025, Supply Chain Security, attack surface mapping, risk prioritization.
Use this skill whenever performing security threat modeling, attack surface mapping, or trust boundary analysis on a codebase. Triggers on 'threat model', 'security review', 'attack surface', 'trust boundaries', or when assessing a project's security posture. Also trigger when the user is about to build security-sensitive features (auth, crypto, file I/O, network services, native bridges) and needs to understand the threat landscape first — even if they don't explicitly say "threat model." Also triggers on 'what changed' or 'diff analysis' for incremental security review of recent commits.
