Hello dear Root-Me community, We're aware of claims circulating on a hacking forum about a Root-Me data leak. We've obtained and analysed the files in question, and here's what we found. No user data is affected. The files contain only challenge source code, no passwords, no emails, no personal information. This is an old leak. Several years ago (prior to 2018, so nearly a decade old), a vulnerability allowed challenge sources from a specific server of ours to be extracted, and someone did exactly that at the time. The material surfacing today appears to originate from that incident. We've since fixed the underlying issue by hardening challenges and ensuring they were all properly sandboxed. There's nothing for our community to action, but if you have questions, we're here to answer them. We thank you all for the responsible reports that brought this to our attention. The Root-Me Team

I started playing CTFs in 2022, and LLMs definitely changed the **competitive** CTF scene a lot, especially since mid-2025. I also started using LLMs in late 2025. Yes, those models did one-shot many challenges, but what's the fun of slopping them? I learned absolutely nothing 🥲

The community have the burden of exposing the frauds in our industry - so let's go! @theXSSrat content is a non sense, he doesn't have the proper skillset nor any credibility in the field to be in a position to either create courses, mentor, or teach anything. #bugbounty
Hey @theXSSrat Since you asked for tagging, here it is.

💣 We caught @ycombinator–backed @gecko_sec stealing two of our CVEs, one on @ollama , one on @Gradio. They copied our PoCs, claimed CVE IDs, and even back-dated their blog posts. Here’s the full story 👇
