Ludushound shows the power of community driven innovation in cybersecurity. @bagelByt3s created an awesome tool to convert bloodhound data into a working lab in 🏟️ Ludus. Replicate complex live environments with automation - and get back to the fun stuff!

Lots of good write ups (like Citrix Bleed 2) but my favorite was seeing how 🏟️ Ludus.cloud helped Cameron Stish of Guidepoint Security find "LoopyTicket" (CVE-2025-33073).

@raphaelmudge.bsky.social summed up why we built and released Ludus open source: "Develop technologies that give individual operators and researchers LEVERAGE acting on hypothesis and make it fast to try things, adapt, and modify."

When spinning up ADCS or SCCM is 3 commands, it gives you leverage.

Cobalt Strike for free!? Adaptix C2 (@hacker_ralf) is the best open source C2 I've used since Havoc (@C5pider). Adaptix has SOCKS5, remote and local port forwards, and BOF support! Now it's easy to install the server and client, especially on 🏟️Ludus with our new role:

The Ludus range config can get complex - lots of features == lots of options, but VSCode (and Cursor/Windsurf) can help if you add:

# yaml-language-server: $schema=https://docs.ludus.cloud/schemas/range-config.json

to the top of a yaml, the editor will highlight and explain errors! 🤯
