A comprehensive playbook for expert-level Android application security testing. It covers advanced exploitation techniques, including SSL pinning bypass (using Frida/Objection), detecting component exposure (activities, providers, services), and exploiting WebView vulnerabilities (RCE, XSS). Essential for authorized mobile penetration testing assessments.

This guide serves as the core entry point for comprehensive security testing of identity and access control mechanisms. It is designed to help testers systematically identify vulnerabilities across login flows, session management, object authorization (IDOR), and modern protocols like JWT, OAuth, CORS, and SAML. Use this when planning security audits for any web application with user accounts.

A comprehensive playbook for identifying authentication vulnerabilities in web applications. Covers advanced topics including SQL injection login bypass, predictable password reset tokens, account enumeration techniques, multi-factor authentication bypass, and brute-force resistance checks. Essential for penetration testers assessing login mechanisms and session management.

This playbook is designed for advanced vulnerability assessment, covering flaws invisible to automated scanners. It guides testing for race conditions, complex workflow bypasses, state machine manipulation, financial parameter tampering (e.g., price/quantity manipulation), and coupon/credit abuse in multi-step applications. Essential for deep manual security testing.

This expert playbook provides comprehensive techniques for testing Cross-Site Request Forgery (CSRF) vulnerabilities in web applications. It covers identifying state-changing endpoints, bypassing anti-CSRF tokens (including missing validation and predictable tokens), and exploiting modern weaknesses like SameSite=Lax via GET methods or misconfigured JSON APIs. Essential reading for security professionals and penetration testers.

A sophisticated payload bypass technique targeting Java applications. It exploits the silent loss of high 8 bits when 16-bit Java characters are cast or written as 8-bit bytes. This allows attackers to bypass WAF/IDS security measures by making the WAF see harmless Unicode, while the backend service processes the original malicious ASCII byte payload. Ideal for blind SQLi, deserialization RCE, and path traversal. This primitive affects major frameworks like Tomcat, Spring, Jackson, and HttpClient.

HTTP Parameter Pollution (HPP) occurs when a single request contains multiple instances of the same parameter key. Different components in the request path (e.g., WAFs, proxies, application frameworks) may parse these duplicate keys using different rules (first value, last value, array join). This skill teaches how to exploit these discrepancies to bypass security checks, execute SSRF, or manipulate business logic.

An expert playbook detailing advanced attacks against JWT and OAuth 2.0 tokens. Covers cryptographic weaknesses like alg:none, key confusion (RS256 to HS256), and header injection (kid, jku). It also addresses critical OAuth flow abuses, such as missing state parameters, account takeover, and token leakage, essential for robust application security testing.

A comprehensive playbook for testing security flaws in OAuth 2.0 and OpenID Connect (OIDC) implementations. Use this guide to systematically check for misconfigurations in redirect URI handling, state and nonce validation, PKCE enforcement, token audience/issuer checks, and account binding vulnerabilities. Essential for reviewing applications linked to external identity providers.

This expert playbook provides comprehensive techniques for exploiting Server-Side Template Injection (SSTI). It covers polyglot detection probes, engine fingerprinting (Jinja2, Twig, FreeMarker, etc.), sandbox escape mechanisms (MRO chains), and advanced bypass techniques. Essential reading for security researchers and penetration testers assessing application vulnerabilities.

A comprehensive guide detailing best practices for securing Quarkus applications. It covers robust authentication methods like JWT and OIDC, role-based access control (RBAC) for authorization, mandatory input validation using Bean Validation, preventing SQL injection, and secure secret management. Essential for developers building highly secure Java microservices.

A comprehensive CI/CD pipeline for Quarkus applications, designed to verify code quality and deployment readiness. It covers all phases: build, static code analysis (SonarQube, Checkstyle), rigorous functional testing (Unit, Integration, API), security scanning (OWASP, dependency checks), native image compatibility testing, performance load testing (K6), and container image validation (Trivy, Grype).
