🚀 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. 🔥

🏴☠️ Proud to sponsor @ph0wn CTF 2026 this weekend including the Skull Island badges!
Amazing hardware/IoT CTF as always. Big thanks to @cryptax and the whole team for the incredible challenges.

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.

Confirmed! Julien COHEN‑SCALI of @FuzzingLabs targeted the Phoenix Contact CHARX SEC‑3150, chaining two vulnerabilities - an authentication bypass and privilege escalation - to earn $20,000 USD and 4 Master of Pwn points. #Pwn2Own #P2OAuto

💥 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.

This runs inside the new FuzzForge v0.7.0:
→ Temporal workflows
→ On-demand vertical workers
→ AI-powered code analysis (SARIF included)

💣 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 👇

Excited to announce that our CEO @Pat_Ventuzelo is giving the Closing Keynote at #BSidesberlin 🎤
AI for AppSec and Offensive Security: From Automation to Autonomy
📅 8 Nov 2025 | 📍 CIC Berlin
AI is reshaping vulnerability research, from audits & #fuzzing to autonomous red teams.
In this keynote, he’ll dive into:
🔹 How AI is applied to code auditing, fuzzing, and vulnerability triage
🔹 The rise of multi-agent systems that act like autonomous red teams
🔹 The challenges of benchmarking, reproducibility, and non-determinism
🔹 What the future may hold: specialized models, autonomous AI red teams, and community-driven collaboration

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

Just got a reward for a high vulnerability submitted on @yeswehack -- Improper Access Control - Generic (CWE-284). #YesWeRHackers
It's done ! I've passed the Android Fuzzer and Exploit Developer certification exam from @MobileHackLab ! 🎉
