Provides expert guidance on secure and performant file upload mechanisms for cloud environments. Covers best practices for using services like AWS S3 and Cloudflare R2, including implementing presigned URLs, handling large files via streaming, and optimizing images. Crucially emphasizes critical security measures such as validating file types using magic bytes, enforcing size limits, and preventing path traversal attacks.

Delivers repository-grounded AppSec threat models that map components, boundaries, assets, entry points, and attacker capabilities to abuse paths, along with prioritized mitigations tailored to codebase evidence and explicit assumptions.

This skill utilizes Impacket to perform comprehensive audits and simulated attacks on Active Directory forest trust relationships. It enumerates trust boundaries, analyzes SID filtering configurations, detects SID history abuse vectors, and assesses inter-realm Kerberos ticket risks. Ideal for red-teaming multi-forest environments or performing deep security audits to find cross-forest privilege escalation paths.

A comprehensive security assessment guide and script to test API rate limit vulnerabilities. It evaluates if an API's security controls can be bypassed using advanced techniques such as IP spoofing (manipulating X-Forwarded-For headers), HTTP method variations, and endpoint path traversal. Designed for penetration testing, it helps assess resilience against brute-force or resource exhaustion attacks, aligning with OWASP API Top 10 findings.

A comprehensive guide and set of payloads for penetration testing web applications that process XML input. It details how to test for major vulnerabilities such as XXE, XPath injection, SSRF, and XML parsing attacks, providing step-by-step workflows and advanced payloads for identifying data exposure and security flaws.

This skill provides a comprehensive, structured methodology and checklist for identifying Remote Code Execution (RCE) vulnerabilities across various web applications. It covers advanced attack vectors such as OS command injection, Server-Side Template Injection (SSTI), insecure deserialization, file upload flaws, and XXE. Use this guide during web application penetration testing or bug bounty hunting to systematically discover arbitrary code execution paths.

Techniques for attacking WPA/WPA2/WPA3-Enterprise 802.1X networks, including EAP method identification, evil-twin RADIUS credential capture, MSCHAPv2 cracking, and EAP-TLS certificate theft paths in corporate Wi-Fi environments.

A comprehensive playbook for bypassing 401/403 Forbidden errors. Covers advanced techniques like path normalization tricks (encoding, traversal), HTTP method tampering, IP spoofing headers, and protocol downgrade attacks. Essential knowledge for penetration testing and security auditing.

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.

This comprehensive playbook details advanced techniques for detecting Prototype Pollution vulnerabilities in JavaScript environments (Node.js and browser). It covers various attack vectors, including using `__proto__` and `constructor.prototype` paths, and provides black-box testing payloads for JSON parsing, query string merging, and deep object assignment. Use this when analyzing applications for potential Remote Code Execution (RCE) or unintended property leakage via object merging sinks.

Entry-level reconnaissance router for new targets and unknown attack surfaces. Helps map scope, discover assets, fingerprint technology, inventory endpoints, and choose the first high-value security testing path.

A comprehensive, expert playbook for challenging insecure file upload mechanisms. It provides advanced attack vectors covering validation bypass (magic bytes, extension), storage path abuse (traversal, overwrite), and exploitation of post-upload processing chains (XXE, RCE, CMDi). Essential for deep security auditing of file-handling workflows.
