🚀 FuzzingLabs is now part of the @NVIDIA Inception Program! We're building FuzzForge, our AI agents platform leveraging GPU infrastructure for Continuous Offensive Validation on firmware, binaries & embedded systems. Scaling fine-tuned Qwen, Gemma & DeepSeek for offensive security. 🔥 #NVIDIAInception #AI #Cybersecurity

We just rewrote FuzzForge from scratch and open-sourced it. Old: Temporal + MinIO + workers + backend. Heavy. New: CLI + MCP server + containerized modules. Zero infra. 🖥️ Runs fully local 🧠 Plug your favorite LLM (Copilot, Claude, local models…) 🔗 AI agents orchestrate full security pipelines via MCP Demo: 4 modules, 3 min, 994 crashes → 3 unique bugs. AI-native security research. github.com/FuzzingLabs/fuzzf…

💥 We’ve just raised €1M in pre-seed funding to accelerate the development of FuzzForge. When I started FuzzingLabs, everything was bootstrapped: our audits, our trainings, our R&D. No investors, no funding. Just a passionate team obsessed with offensive security and the belief that we could build something different. Three years later, we’re 30 and we are now entering a new chapter. This funding will allow us to: - accelerate the open-source development of FuzzForge, - build its marketplace of agents and workflows, - and expand the SaaS version to automate vulnerability research at scale. A huge thanks to @class_lambda and @ergodicgroup for their strategic support and trust in our vision: --> making offensive security more intelligent, collaborative, and automated. FuzzForge is already open source and under active development. You can check it out here: 🔗 github.com/FuzzingLabs/fuzzf…

💣 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 👇

🔍 Android obfuscation ≠ protection. 🤖 We let an LLM-powered CLI loose on nasty APKs — and it turned byte-code spaghetti into plain English in minutes. 🧵
