TLS 1.3 is the latest Transport Layer Security protocol, offering significant security and performance improvements over TLS 1.2. This guide details how to configure and validate TLS 1.3 on various environments, including Nginx, Apache, and Python applications. It covers advanced topics such as Perfect Forward Secrecy (PFS), HSTS implementation, modern cipher suites, and best practices for securing modern web services.

Guides SOC teams through validating alerts, isolating networks and endpoints, preserving evidence, and disabling compromised accounts to rapidly contain an active breach while minimizing business impact.

This guide teaches security teams how to deploy and operationalize Amazon GuardDuty for continuous, comprehensive threat detection across entire AWS accounts and workloads. It covers enabling protection plans for S3, EKS, EC2 runtime monitoring, and Lambda, interpreting various finding severity levels, and building robust, automated incident response playbooks using EventBridge and AWS Lambda for immediate containment actions.

This guide provides a comprehensive methodology and technical approach for detecting malicious email forwarding rules. It is crucial for threat hunting, incident response, and proactive security assessments to identify persistent access mechanisms used by adversaries for intelligence collection and Business Email Compromise (BEC) attacks. It outlines necessary prerequisites, workflow steps, and key threat indicators (T1114).

This comprehensive guide details the methodology for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities. It teaches users how to systematically test broken access control in modern web applications and APIs. By manipulating predictable object identifiers (such as user IDs, order numbers, or document slugs), testers can validate if object-level authorization is properly enforced, preventing unauthorized horizontal or vertical data access.

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 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 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 set of payloads for detecting and exploiting Server-Side Template Injection (SSTI) vulnerabilities. This skill covers various template engines like Jinja2, Twig, Freemarker, and more, allowing users to achieve Remote Code Execution (RCE) during penetration testing.

This skill details the exploitation of the critical Zerologon vulnerability (CVE-2020-1472) found in the Microsoft Netlogon Remote Protocol. It allows an unauthenticated attacker to compromise a domain controller by resetting its machine account password. The guide covers the complete attack chain, including initial exploitation, credential dumping via DCSync, and subsequent privilege escalation in Active Directory environments. Used exclusively for authorized red teaming and security testing.

This skill covers implementing robust API rate limiting and throttling controls using advanced algorithms like token bucket and sliding window. It teaches how to protect backend systems against attacks such as brute force, credential stuffing, and resource exhaustion. Key components include configuring limits per user, per IP, and per endpoint, utilizing Redis for distributed counting, and implementing proper HTTP 429 responses for effective abuse prevention.

This guide details how to implement comprehensive API security testing using the 42Crunch platform. It performs static audits of OpenAPI specifications (API Audit) and dynamic vulnerability scanning (Conformance Scan) against live APIs. Supports integration into CI/CD pipelines to proactively discover OWASP API Top 10 vulnerabilities, enabling a Shift-Left security approach.
