This guide provides comprehensive best practices for creating optimized, secure, and efficient multi-stage Dockerfiles. Learn how to separate build environments (builder stage) from minimal runtime environments, significantly reducing image size and attack surface. Topics covered include layer caching optimization, security hardening (non-root users), and using minimal base images for reproducible builds.

Provides comprehensive security guidelines for integrating Anthropic Claude API. Covers essential best practices including secure API key management (rotation, isolation), defending against prompt injection attacks by separating system instructions from user input, robust input sanitization, and output validation to prevent accidental data leakage. Essential for building production-grade, secure AI applications.

Detects goal hijacking vulnerabilities where malicious instructions are hidden within external content sources processed by the agent, such as retrieved documents (RAG), uploaded files, or web page content. This skill simulates these attack vectors to ensure the agent only uses the provided context for the stated task and does not execute embedded hidden commands.

This guide details essential best practices for securing applications integrated with Anthropic's Claude API. It covers critical security measures including secure API key management (server-side only), robust input validation to prevent cost attacks, defense mechanisms against prompt injection, and implementing per-user rate limiting. Essential reading for maintaining data privacy and system integrity in production environments.

A comprehensive methodology for discovering potential software vulnerabilities. It outlines advanced techniques including static analysis, dynamic analysis, fuzzing, taint tracking, and modern attack surface mapping (e.g., kernel, drivers). Ideal for professional code audits, bug bounty hunting, and building robust vulnerability research pipelines.

This skill guides the comprehensive process of crash triage, enabling the assessment of vulnerability exploitability. It covers advanced techniques using debuggers (WinDbg/GDB), sanitizers (ASAN/MSAN), and interpreting low-level data like stack traces and register dumps. It is essential for vulnerability researchers analyzing crash dumps or fuzzer-generated failures to identify root causes and potential attack vectors.

This is a detailed offensive checklist for identifying and exploiting insecure deserialization vulnerabilities across multiple programming languages (Java, Python, PHP, .NET, Node.js, etc.). It covers techniques like gadget chain generation, magic method abuse, type confusion, and modern attack vectors, providing a deep methodology for penetration testing and vulnerability research.

A comprehensive checklist designed for assessing the security posture of GraphQL endpoints. It covers advanced vulnerabilities such as introspection abuse, IDOR, query depth/complexity DoS, injection attacks (SQLi/NoSQLi), and authorization bypass mechanisms. Essential for professional penetration testing and bug bounty hunting.

This comprehensive checklist provides a detailed methodology for simulating the initial access phase in red team engagements and penetration testing. It covers a wide spectrum of modern attack vectors, including advanced social engineering (e.g., deepfake, BEC), sophisticated phishing (spear/smishing), exploiting exposed perimeter services (RDP/VPN), and identifying cloud misconfigurations. Use this guide when planning or executing the initial foothold stage to ensure comprehensive coverage against modern threats.

A comprehensive checklist detailing advanced attack methodologies for JSON Web Tokens (JWT). Covers critical misconfigurations such as algorithm confusion (alg:none, RS256→HS256), weak secret brute forcing, header injection (kid, jku, jwk), cache poisoning, and improper validation. Also provides specific vectors for extracting JWTs from mobile environments (Android/iOS). Ideal for penetration testers conducting deep security assessments on authentication systems.

A comprehensive reference and bypass catalog covering modern operating system kernel mitigations such as KASLR, SMAP, SMEP, KPTI, DEP/NX, and CFI. It details how these security mechanisms function, how to detect their presence, and advanced bypass techniques (e.g., side-channel attacks, ROP chains, information leaks). This skill is essential for security professionals conducting deep penetration testing, exploit development, and target hardening assessments.

A comprehensive methodology for offensive security, red team intelligence gathering, and bug bounty reconnaissance. Covers domain recon, email harvesting, social media profiling, code leaks, infrastructure mapping, cryptocurrency tracing, and geospatial intelligence. Essential for building detailed attack-surface maps against organizations or individuals.
