Advanced Kerberos Attack Playbook for Active Directory

active-directory-kerberos-attacks

yaklang/hack-skills

A comprehensive guide covering advanced Kerberos attacks against Active Directory environments. Techniques include AS-REP roasting, Kerberoasting, forging golden, silver, diamond, and sapphire tickets, and exploiting delegation abuse. Designed for penetration testers and red teams to simulate sophisticated domain compromise scenarios.

API Authorization and BOLA Testing

api-authorization-and-bola

yaklang/hack-skills

This comprehensive playbook guides security testers through deep API authorization checks, focusing specifically on BOLA (Broken Object Level Authorization) and BFLA (Broken Function Level Authorization). Use this skill to test scenarios where object identifiers, nested resources, or privileged functions are exposed, ensuring thorough checks for mass assignment and privilege escalation.

Authentication and Authorization Security Router

yaklang/hack-skills

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.

V8 and Browser Exploitation Playbook

browser-exploitation-v8

yaklang/hack-skills

A comprehensive playbook covering advanced V8 and Chromium exploitation techniques. It details complex vulnerabilities such as JIT type confusion, incorrect bounds elimination, and pointer compression bypass. This guide is essential for understanding the mechanisms required to achieve renderer RCE and sandbox escape in modern browsers.

Business Logic Vulnerability Router

business-logic-vuln

yaklang/hack-skills

This router guides the testing of systemic flaws in business processes and state machines. It is essential when vulnerabilities stem from workflow abuse, race conditions, pricing flaws, or multi-step state attacks, rather than simple input sanitation issues. Use it to test complex business flows like payments, inventory management, and approval sequences.

Business Logic Vulnerability Expert Playbook

business-logic-vulnerabilities

yaklang/hack-skills

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.

Expert Classical Cipher Analysis Guide

classical-cipher-analysis

yaklang/hack-skills

This comprehensive playbook provides expert techniques for classical cipher identification and breaking. It covers fundamental methods like frequency analysis, Kasiski examination, and Index of Coincidence (IC), enabling the decryption of monoalphabetic, polyalphabetic, and transposition ciphers (Vigenere, Caesar, Playfair, etc.). It also guides the decoding of various formats (Base64, Hex, Morse).

Clickjacking Attack Playbook

yaklang/hack-skills

A comprehensive playbook for identifying and exploiting clickjacking vulnerabilities (UI redress). Learn how to test if target pages can be framed, bypass security headers like X-Frame-Options and CSP frame-ancestors, and execute high-impact actions through invisible iframes. This guide covers single-click, multi-step, and drag-and-drop attack vectors, applicable to sensitive endpoints like account deletion or admin panels.

Expert Guide to OS Command Injection

cmdi-command-injection

yaklang/hack-skills

A comprehensive playbook detailing expert techniques for OS command injection vulnerabilities. It covers all shell metacharacters, blind injection, time-based detection, out-of-band exfiltration methods, and common vulnerable code patterns across PHP, Python, and Node.js. Essential for security analysts and penetration testers.

Cross-Origin Misconfiguration Testing Guide

cors-cross-origin-misconfiguration

yaklang/hack-skills

This comprehensive playbook guides the testing of Cross-Origin Resource Sharing (CORS) misconfigurations. It focuses on detecting critical vulnerabilities such as reflected origins, wildcard trust misuse, credentialed cross-origin reads, and bypasses in origin allowlists. Use this when analyzing browser-based access and trust boundaries for authenticated APIs.

Advanced Content Security Policy Bypass Techniques

csp-bypass-advanced

yaklang/hack-skills

This comprehensive guide details advanced techniques for circumventing Content Security Policies (CSP). It covers exploiting weaknesses in critical directives (e.g., base-uri, object-src), abusing nonces, leveraging trusted CDN endpoints, and executing code despite strict controls like script-src 'self' or 'strict-dynamic'. Essential knowledge for deep security auditing and penetration testing.

Dependency Confusion Supply Chain Attacks

dependency-confusion

yaklang/hack-skills

An expert playbook for identifying and simulating dependency confusion attacks in software supply chains. It comprehensively covers how internal package names can be squatted on public registries, leading to malicious code execution via package manager lifecycle hooks (e.g., npm, pip, Maven). Use this guide for authorized red-team exercises and deep vulnerability assessment of build processes.
