    BerserkArch

    BerserkArch

    A bleeding-edge, security-centric Arch-based Linux distribution.

    BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners.

    Illicit Reality

    Penetration distro with a lot of shortcuts and gaudy desktop

    Illicit Reality is a distro based on Debian with Xfce4. It holds a lot of penetration testing tools. Instead of having to type everything you can use handy shortcuts. These shortcuts will start an entire penetration test on the target you are currently viewing and will also automate the whole process of becoming "anonymous" whilst scanning and exploiting your target. This distro will be for educational purposes only and for penetration tests for which you are authorised to do. If you are not authorised to do the penetration test you are responsible for the consequences of your own actions.
