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.

A comprehensive playbook detailing how web applications can be vulnerable to attacks by manipulating the HTTP Host header. Covers critical techniques such as password reset poisoning, Web Cache Poisoning, Server-Side Request Forgery (SSRF), and Virtual Host bypass. Essential reading for penetration testers and security researchers.

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.

This skill guides the detection and recovery of exposed version-control system (VCS) metadata, including paths for Git, SVN, and Mercurial, as well as common backup and configuration files. It is essential for authorized penetration testing when assessing an application's security posture against information leaks. Techniques include probing specific directories (e.g., /.git/HEAD) and analyzing status codes (e.g., 403 vs 404) to confirm exposure.

A comprehensive playbook for advanced mobile security assessments of iOS applications. Covers both jailbroken and non-jailbroken environments, focusing on critical attack vectors such as keychain extraction, URL scheme hijacking, Universal Links exploitation via AASA misconfigurations, runtime memory manipulation (Frida/Objection), and binary protection analysis.

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 expert playbook detailing advanced Large Language Model (LLM) prompt injection techniques. Covers direct methods (instruction override, role play), indirect attacks (RAG poisoning, web data manipulation), and sophisticated tool/function calling abuse for data exfiltration and security bypass. Essential for rigorous AI 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.

A comprehensive playbook for advanced security testing, focusing on race conditions and TOCTOU (Time-of-check to time-of-use) vulnerabilities in web applications. It guides users to exploit non-atomic, state-changing operations (e.g., coupons, balance deductions, single-use rewards) by sending highly synchronized, parallel requests (including HTTP/2 single-packet attacks). Essential for identifying weaknesses in authorization and transactional integrity.
