Black Hat Asia 2026, wrapped. ✅ It's always something special being in a room full of people who genuinely care about making the security space better. Great conversations, sharp minds, and a few sessions that genuinely made us think differently. Big thanks to everyone who stopped by and connected with our team. See you at the next one. #BlackHatAsia2026 #CTEM #AIExposure #RedHuntLabs #Cybersecurity
The response Shubham Mittal (@upgoingstar) got after his talk "No CVE for That" at @nullcon Goa 2026 was incredible and we didn't want it to stop there. We've put the full deck on SlideShare so the wider security community can make benefit from this research talk. Access the full deck here: slideshare.net/slideshow/no-c… From exposed Ollama instances to leaked OpenAI keys to unauthenticated vector databases, the AI stack is the new attack surface, and most organizations have zero visibility into it. If you're building with AI, securing it, or advising teams that are, this one's for you and worth sharing. #AISecurity #CTEM #LLMSecurity #AIExposure #RedHuntLabs
Merry Christmas to the only community that understands that Santa is clearly one of us. Think about it: 1. He procrastinates for 364 days. 2. He pulls a global all-nighter fueled by sugar and deadline panic. 3. He completes the entire year's work in a manic 8-hour hyperfocus fugue state. He is the Patron Saint of Executive Dysfunction. We claim him. 🎄
