Skill UI

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.

This comprehensive guide outlines techniques for authorized penetration testing of real-time web applications using WebSocket connections. It covers discovering various WebSocket endpoints, testing for authentication bypass, identifying Cross-Site WebSocket Hijacking (CSWSH) vulnerabilities, and assessing message handling for injection flaws (SQLi, XSS). Essential for securing chat, trading, and live notification platforms.

This skill detects anti-forensic timestomping by analyzing NTFS Master File Table (MFT) entries. It compares timestamps from the $STANDARD_INFORMATION attribute (user-modifiable) against the $FILE_NAME attribute (kernel-protected). Discrepancies, such as SI Created < FN Created, strongly indicate malicious manipulation and defense evasion. This methodology is crucial for advanced threat hunting and digital forensic investigations.

This skill provides a deep dive into implementing robust End-to-End Encryption (E2EE) for messaging applications. It simulates key components of the Signal Protocol, including X3DH for initial key exchange and the Double Ratchet algorithm for ongoing key management. It ensures forward secrecy, meaning even if a key is compromised, past messages remain secure. Use this when building highly secure, compliant communication systems.

This skill guides the implementation of envelope encryption using AWS Key Management Service (KMS). Envelope encryption is a robust security pattern where data is encrypted locally using a Data Encryption Key (DEK), and the DEK itself is protected by a master Key Encryption Key (KEK) managed by AWS KMS. This approach overcomes the limitations of direct KMS encryption, enabling unlimited data size encryption, reducing latency, and allowing offline encryption capabilities by keeping the master key secure in an HSM.

This utility implements an append-only log integrity chain using SHA-256 hash chaining. It ensures tamper detection by linking each log entry to the previous one, forming a blockchain-like structure. Functions include log ingestion, chain verification, pinpoint tamper detection, and anchoring to external timestamping services for robust audit logging and compliance.

Implement Kubernetes RBAC to enforce least-privilege access across namespaces, covering Role/ClusterRole design, binding configuration, service account hardening, OIDC integration, and audit logging for multi-tenant clusters.

A comprehensive guide to securing Kubernetes Role-Based Access Control (RBAC). It teaches best practices for implementing least-privilege policies, eliminating excessive cluster-admin bindings, utilizing namespace-scoped roles, and integrating external identity providers (OIDC) to mitigate risks like privilege escalation and unauthorized data access.

A comprehensive guide detailing advanced techniques for bypassing Web Application Firewalls (WAFs). It covers multiple evasion methods, including various encoding schemes (URL, Unicode, HTML entities), payload obfuscation (mixed case, comments), and manipulation of HTTP protocols (methods, headers, parameter pollution). This skill is crucial for penetration testing, red team engagements, and evaluating the robustness of perimeter security controls against sophisticated attacks like SQL Injection and XSS.

A comprehensive 7-stage workflow designed to manage, audit, and optimize GitHub repositories. This tool automates critical tasks including identifying hardcoded secrets, cleaning up junk files, performing deep documentation reviews, benchmarking against competitors, and validating the final state, transforming messy codebases into production-ready assets.

MCPB is a specialized local server bundle that packages the entire runtime environment (Node.js or Python) alongside the server code. It allows developers to distribute and run complex MCP services directly on a user's machine without requiring the user to pre-install specific runtimes or toolchains. Use this when the server must interact with the local filesystem, desktop applications, or OS-level APIs.

This tool detects malicious packages mimicking legitimate dependencies in npm and PyPI. It analyzes package names using Levenshtein distance, examines publish date heuristics, and identifies download count anomalies to secure the software supply chain. Ideal for auditing project dependencies and proactively monitoring for supply chain threats.
