    PentestGPT

    PentestGPT

    Automated Penetration Testing Agentic Framework Powered by LLMs

    PentestGPT is an AI-powered autonomous penetration testing agent designed to perform intelligent, end-to-end security assessments using large language models. Published at USENIX Security 2024, it combines advanced reasoning with an agentic workflow to automate tasks traditionally handled by human pentesters. The platform supports multiple penetration testing categories, including web security, cryptography, reversing, forensics, privilege escalation, and binary exploitation. PentestGPT runs in a Docker-first environment, providing a secure, reproducible setup with built-in tooling and session persistence. It offers real-time feedback and live walkthroughs, allowing users to observe each step of the testing process as it unfolds. Built with a modular and extensible architecture, PentestGPT supports cloud and local LLMs, making it suitable for research, education, and authorized security testing.

    Masscan

    Mass IP port scanner

    Masscan is an Internet-scale port scanner, able to scan the entire Internet in just 6 minutes or less. It's considered the fastest port scanner and is similar to the famous port scanner nmap, and like port scanners scanrand and unicornscan it uses asynchronous transmissions. However, it is more flexible when it comes to arbitrary port and address ranges. Masscan not only detects when ports are open, it can also check banners. And while it is useful for smaller, internal networks, it's designed with the entire internet in mind. Do take note however that Masscan uses its own custom TCP/IP stack, so anything other than a simple port scan could cause conflict with the local TCP/IP stack unless certain configurations are done.

    OSINT Framework

    OSINT Framework

    OSINT Framework

    OSINT-Framework is a web-based intelligence resource map designed to help investigators and researchers quickly locate free open-source intelligence tools and data sources. Rather than functioning as an automated scanner, it organizes hundreds of OSINT resources into a structured, navigable interface grouped by investigation type, such as usernames, email addresses, domains, and social media. The project was originally created from an information security perspective but has since expanded to support journalists, analysts, and digital investigators across many disciplines. Its value lies in curation and discoverability, allowing users to pivot rapidly between relevant intelligence tools during investigations. The framework includes indicators showing whether a resource requires registration, manual editing, or local installation, improving workflow planning.

    DAR - Disk ARchive

    DAR - Disk ARchive

    For full, incremental, compressed and encrypted backups or archives

    DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html
