Brakeman is a static analysis security tool and scanner specifically designed for Ruby on Rails source code. It identifies common security vulnerabilities, such as injection and cross-site scripting, by analyzing the application codebase without executing the application. The tool functions as a security auditor that detects mass assignment risks and template vulnerabilities. It evaluates the final output of rendered views and identifies unrestricted assignment patterns that could allow unauthorized modification of model attributes. The system provides vulnerability management through the us

Linter for dangerous Postgres migration patterns in Diesel and SQLx. Prevents downtime caused by unsafe schema changes.

weggli is a fast and robust semantic search tool for C and C++ codebases. It is designed to help security researchers identify interesting functionality in large codebases.

DeepAudit is a privacy-preserving code audit platform that combines multiple specialized AI agents to identify and verify security vulnerabilities in source code. It functions as a local LLM vulnerability scanner, an automated security report generator, and a sandboxed exploit verifier, all operating entirely within an internal network to keep sensitive code and data on premises. What distinguishes DeepAudit is its multi-agent cooperative approach: teams of AI agents jointly plan, analyze, and cross-check findings across the codebase, moving beyond single-pass scanning. The platform also sand

AllHackingTools is a security tool orchestrator and suite designed to install, update, and manage a wide array of third-party hacking and security utilities from a single command interface. It functions as a centralized hub for network analysis, open source intelligence, penetration testing, and social engineering tools. The project provides specialized frameworks for gathering open source intelligence and searching for user profiles across social platforms. It includes toolkits for network reconnaissance, vulnerability scanning, and the execution of security exploits, as well as a social eng

This project is a suite of automated tools and an LLM code review framework designed for design auditing, security scanning, and AI-driven code analysis. It functions as a developer workflow orchestrator that uses static analysis agents and agent-based workflows to automate pull request analysis and security audits. The system employs a dual-loop agent architecture to coordinate primary analysis and secondary verification, reducing false positives. It distinguishes itself through the use of browser automation to perform live UI component testing and verify frontend changes against accessibili

Pyre is a high-performance static type checker and analysis tool for Python. It identifies type errors and ensures type safety without executing the program, utilizing a static type inference engine to maintain consistency across functions. The project is distinguished by an incremental type analysis engine that operates as a background daemon. This system monitors filesystem changes to re-validate only modified parts of a project, reducing the time required for repeated analysis. It also includes a static analysis security tool that uses taint analysis to track untrusted data flows and ident

CrackMapExec is a network penetration testing framework and automated security scanner designed to assess security postures across large IP ranges. It functions as a multi-protocol security scanner and network protocol auditor used to identify vulnerabilities and misconfigurations. The tool provides capabilities for Active Directory auditing to enumerate users and permissions, as well as post-exploitation enumeration to gather system metadata and discover lateral movement paths. It includes a framework for credential spraying and harvesting across various network services. The system utilize

cloc is a codebase metrics tool and multi-language code analyzer designed to count blank lines, comment lines, and physical lines of code. It serves as a source code line counter and report generator that identifies file types to calculate source volume across a wide variety of programming languages. The tool distinguishes itself by providing codebase version comparison to measure relative changes in source and comment lines between two versions of a directory or archive. It also supports the definition of custom languages and the extension of language recognition by loading custom comment fi

my-git is a comprehensive framework and reference guide for Git version control administration, repository governance, and software release management. It provides a structured approach to managing the software development lifecycle, from initial feature branching to final production deployment.
