A comprehensive guide for authorized penetration testers on identifying and exploiting insecure deserialization vulnerabilities across multiple languages (Java, PHP, Python, .NET). Covers techniques for generating payloads using tools like ysoserial and phpggc, and testing various application components such as cookies, HTTP parameters, and message queues to achieve potential Remote Code Execution (RCE).

This comprehensive guide outlines methods to identify and exploit specific IPv6 vulnerabilities, including SLAAC spoofing, Router Advertisement (RA) manipulation, and Neighbor Discovery Protocol (NDP) attacks. It is designed strictly for authorized penetration testing to assess dual-stack security controls, detect unauthorized tunnels (like Teredo or 6to4), and validate network defenses against IPv6-specific threats. Always obtain explicit written authorization before use.

This skill demonstrates how to exploit JWT algorithm confusion vulnerabilities. It targets APIs that do not strictly enforce the cryptographic algorithm (alg) specified in the token header. Techniques covered include downgrading from asymmetric algorithms (RS256) to symmetric ones (HS256) using the public key as the secret, performing alg:none bypasses, and manipulating key identifiers (kid, jku, x5u) to achieve authentication bypass and token forgery.

A comprehensive guide detailing the Kerberoasting technique (T1558.003) used in Active Directory environments. This method exploits service accounts by requesting and subsequently cracking Kerberos TGS tickets offline, allowing attackers to compromise credentials. Instructions cover enumeration, ticket request, cracking with tools like Hashcat/John the Ripper, and credential validation, for authorized red team and penetration testing purposes.

A detailed guide on discovering and exploiting Mass Assignment vulnerabilities in REST APIs. Users learn to inject unexpected parameters into API requests (POST, PUT, PATCH) to bypass authorization controls, escalate privileges (e.g., changing 'role'), and modify sensitive fields (e.g., 'balance', 'isAdmin') during security assessments and bug bounty hunting.

Detailed guide on exploiting the critical MS17-010 (EternalBlue) vulnerability in SMBv1 protocol. This technique allows for remote code execution (RCE) on unpatched Windows systems. Primarily used in authorized red teaming, penetration testing, and advanced security analysis to simulate real-world attacks and assess network defense posture.

This skill details exploiting the noPac vulnerability chain, combining CVE-2021-42278 (sAMAccountName spoofing) and CVE-2021-42287 (KDC PAC confusion). It allows an authenticated standard domain user to escalate privileges to Domain Admin, potentially compromising the entire domain. It is designed for authorized red team exercises and penetration testing against vulnerable Active Directory environments.

This comprehensive guide details advanced techniques for detecting and exploiting NoSQL injection vulnerabilities across various databases like MongoDB and CouchDB. It covers critical attack vectors, including authentication bypass using operators ($ne, $gt), blind data extraction via $regex, and executing arbitrary server-side JavaScript through the $where clause. Essential reading for penetration testers and security researchers assessing NoSQL backends.

A comprehensive guide for penetration testers detailing methods to identify and exploit misconfigurations in OAuth 2.0 and OpenID Connect (OIDC) flows. Techniques cover redirect URI manipulation, authorization code theft, token leakage via headers, and scope escalation during security assessments.

A comprehensive skill for detecting and exploiting JavaScript prototype pollution vulnerabilities in both client-side and server-side applications. It demonstrates advanced property injection techniques to achieve critical security outcomes, including Cross-Site Scripting (XSS), Remote Code Execution (RCE), and authentication/authorization bypass, especially in Node.js environments and JSON merging scenarios.

A comprehensive guide and technique set for detecting and exploiting race condition vulnerabilities in web applications. It focuses on bypassing rate limits, exploiting Time-of-Check-to-Time-of-Use (TOCTOU) flaws, and duplicating transactions using advanced methods like Turbo Intruder's single-packet attack. Ideal for security assessments of state-changing operations (e.g., payments, inventory management, coupon redemption).

A comprehensive guide detailing the methodology for identifying and exploiting Server-Side Request Forgery (SSRF). This technique is critical in authorized penetration testing, allowing attackers to pivot from public-facing applications to internal resources. Use cases include stealing cloud provider metadata (AWS, GCP), scanning private IP ranges, and accessing internal APIs and admin panels.
