offensive-osint
Offensive OSINT Methodology provides a structured reconnaissance workflow for gathering open-source intelligence on targets including domains, organizations, individuals, cryptocurrency addresses, and geographic subjects. The skill directs users through target scoping, tool selection across categories like username investigation, domain enumeration, social media profiling, breach data lookup, and infrastructure mapping, with emphasis on artifact archival and reproducible logging. Use this skill when conducting red team reconnaissance, bug bounty scoping, threat intelligence gathering, or building comprehensive attack surface maps.

# Offensive OSINT Methodology ## Workflow 1. Define target scope (domain, org, person, crypto address, or geo subject) 2. Select applicable categories below based on scope 3. Work top-down within each category; pivot on discovered artifacts 4. Archive every key artifact: URL + timestamp + screenshot (PNG) + hash (SHA-256) 5. Log findings in JSONL with a `run_id` and tool versions for reproducibility 6. Suggest next steps based on what each tool returns --- ## General OSINT - [Bookmarks](https://tools.myosint.training/) — Comprehensive OSINT bookmarks - [OSINT Framework](https://osintframework.com/) — Tool/resource directory - [IntelTechniques Tools](https://inteltechniques.com/tools/) — Suite of investigative tools - [Bellingcat Toolkit](https://www.bellingcat.com/resources/2024/09/24/bellingcat-online-investigations-toolkit/) — Investigative journalism tools - [CyberSudo OSINT Toolkit](https://docs.google.com/spreadsheets/d/1EC0sKA_W9znzsxUt0wye9UYtyATXw5m8) — OSINT websites list - [Google Dorks](https://dorksearch.com/) — Efficient Google searching - [Distributed Denial of Secrets](https://ddosecrets.com/) — Leaked data - [Country-Specific Resources](https://digitaldigging.org/osint/) — Country-targeted OSINT ### Search Engines | Tool | Notes | |------|-------| | [Carrot2](https://search.carrot2.org/#/search/web) | Clusters results by topic | | [etools](https://www.etools.ch/) | Metasearch engine | | [Kagi](https://kagi.com/) | Privacy-first, non-personalized results | | [Brave Search](https://search.brave.com/) | Independent index;

Aligns to MITRE ATT&CK T1070 (Indicator Removal), T1027 (Obfuscated Files or Information), T1497 (Virtualization/Sandbox Evasion). Each technique includes the forensic artifact it targets, the destruction or manipulation method, and the defender perspective so operators understand detection gaps they must account for.
Advanced API exploitation methodology focused on business logic abuse and sophisticated attack patterns that bypass traditional security controls. Covers business logic bypass through API call chaining and workflow manipulation. Addresses GraphQL-specific attacks including batching for credential brute-force, query depth exploitation, and introspection abuse. Includes pagination exploitation for data exfiltration, webhook hijacking for SSRF and data interception, and resource exhaustion through algorithmic complexity attacks. Covers race conditions in API transactions using parallel request techniques. Provides comprehensive JWT manipulation including algorithm confusion, kid injection, jku/x5u abuse, and claim tampering. Details API key leakage detection across source repositories, client-side code, and error messages. Covers undocumented endpoint discovery through predictable naming, debug routes, and source map analysis. Tooling includes Arjun, ParamSpider, jwt_tool, and GraphQL Voyager. Designed for authorized penetration testers targeting business logic layers that automated scanners miss.
Comprehensive API security testing methodology covering REST, gRPC, and WebSocket attack surfaces. Addresses the full OWASP API Security Top 10 2023 including BOLA/IDOR, broken authentication, excessive data exposure, rate limiting bypass, BFLA, mass assignment, SSRF, and security misconfiguration. Includes REST-specific attacks such as HTTP verb tampering, content-type switching, and parameter pollution. Covers gRPC exploitation through protobuf interception, reflection API enumeration, and metadata injection. Addresses WebSocket vulnerabilities including origin bypass, message injection, and cross-site WebSocket hijacking. Provides tooling guidance for Burp Suite, Postman, grpcurl, websocat, and mitmproxy. Each technique includes detection signatures and defensive indicators so you understand what artifacts your testing leaves behind. Designed for authorized penetration testing engagements against API-driven architectures.
