Bridging AI and Cybersecurity

My new interpretability paper is out! Unsupervised Features Mining via Activation Geometry. Many interpretability methods start with labeled examples of a human-defined concept, then look for that concept inside the model. We propose MAG Mining via Activation Geometry, an unsupervised framework for extracting model-relative reasoning features directly from activations. For each input p, we prepend the same instruction Q, such as โ€œIs this prompt malicious?โ€ or โ€œCan this object be found in the desert?โ€, and measure the activation shift m(Q \| p)-m(p). This shift captures how the modelโ€™s internal representation changes when it is asked to reason about that feature.

I might stay here in Silicon Valley for a while. Things are moving crazy fast. Canโ€™t share much yet, but the team has grown a lot, and weโ€™ve done more in two weeks than some really successful companies did in their first six months. Hard to believe that just 14 days ago, I was heading to another conference. Life is so unpredictable.
If you truly care about AI safety, AI cybersecurity is where you should be. Cyber defenses were built against humans, not AI agents. Today, thousands of agents can attack enterprises without anyone even noticing. We need AI researchers in this space more than ever. I believe this is one of the biggest risks AI poses to humanity, and also a massive market opportunity. Without any hype bullshit.

Humanity is facing a major risk right now, and I think everyone needs to be aware of it. Ten days ago, we were just heading to another conference. I never imagined that almost everyone we spoke to about our perspective, would want to get involved through investment, partnerships, or collaboration. From industry leaders to major enterprises, Thatโ€™s when we realized how urgent this really is. Iโ€™m genuinely worried about where weโ€™ll be six months from now. Throughout history, new cybersecurity categories emerged after major technology adaptations. Companies moved to the internet โ†’ Network Security โ†’ Check Point. Companies moved to the cloud โ†’ Cloud Security โ†’ Wiz. Companies adopted AI โ†’ AI Security โ†’ Zenity. But this time, something is different, there is NO ADAPTATION! Itโ€™s not just the technology weโ€™re protecting thatโ€™s changing. The attacker itself is changing. Almost every security product today was designed for human cyber attackers. But what happens when thousands of AI agents can attack the same organization 24/7, learning, adapting, and trying again, with exponential reverse engineering capabilities? The scary part? Today, 5000 AI agents can attack an organization without it even knowing, because existing security defenses simply werenโ€™t built to stop AI attackers. And solving this isnโ€™t just another cybersecurity challenge. It requires a rare combination of deep AI research and cybersecurity expertise. Look at the graph. Open-source cyber AI models have made incredible progress in just the past few months. At the same time, some sectors have reportedly seen enterprise attacks increase by 4โ€“5x ( not according the graph but according our partnership) Weโ€™re entering the era of vibe hacking. Just like AI made software development accessible to almost anyone, itโ€™s making offensive cyber capabilities accessible to people who previously needed years of technical expertise. And I donโ€™t think most people realize how fast this is happening. This is the biggest AI safety challenges humanity faces in our time. Not years from now. NOW. About 10 days ago, we left Israel without really knowing what to expect, just to visit another conference. We came to meet people, attend conferences, explore, and validate something weโ€™d been thinking about before. What happened next surprised me. In those 10 days, between conferences, traveling, and endless conversations, I feel like we learned what would normally take us 2โ€“3 years. The feedback, the validation, the people who want to get involved. Everything moved much faster than we expected. And thatโ€™s why Iโ€™m writing this. I never imagined Iโ€™d publicly talk about the problem weโ€™re building a company to solve before weโ€™d even properly started. Definitely not this early. But after everything weโ€™ve seen and heard, waiting another six months just doesnโ€™t make sense. This is bigger than another cybersecurity startup. Itโ€™s a problem with implications for all of us. So weโ€™ve decided to start talking openly, even though weโ€™re still at the very beginning. I wasnโ€™t planning to share any of this for at least another six months. But who knows what the world will look like by then? Fuck it. Weโ€™re doing this.

Iโ€™m resign from my PhD in the final year. After 4.5 years at Technion university, from bachelorโ€™s to masterโ€™s to PhD, 15 papers, hundreds of researchers Iโ€™ve worked with, two years of teaching, and helping build what I believe is now one of Israelโ€™s leading academic AI security and safety labs. Not an easy decision.

So Iโ€™m leaving academia, at least for now. Iโ€™m incredibly grateful to the Technion, my professor, my collaborators, and everyone who was part of these 4.5 years. This isnโ€™t how I imagined this chapter ending. But the mission matters more than the diploma. And right now, I feel I have a duty to act.

Iโ€™m still here. And every day here has made one thing clearer: this problem is more urgent than I thought. I really wanted to finish my PhD. I was so close. But I believe thereโ€™s somewhere else I can make a greater impact right now. And waiting until itโ€™s too late to act is a risk Iโ€™m not willing to take.

About 10 days ago, I gave a talk at one of the top international security conferences BlackHat Canada, on main stage For the first three minutes, I went completely off-script and spoke about this problem. It wasnโ€™t even related to my talk. Just something I felt the audience needed to hear. After that, I flew to Silicon valley to understand the problem better.

My mission has always been to minimize the risks AI could pose to humanity. And I believe part of that responsibility is understanding not only what the risks are, but to stop them before itโ€™s become too late. Sometimes timing matters more than anything.

Iโ€™m not leaving because I donโ€™t love the Technion and my research. I really do๐Ÿ’” And definitely not because thereโ€™s nothing left to research in interpretability and alignment. Quite the opposite. Iโ€™m leaving because of something else. Something not directly in AI, but being deeply affected by it.

How will AI change the way we shop for clothes? Imagine walking into a store where everything is personalized to your taste. I think weโ€™re heading toward a future where AI generates unique products in real time, just for you, and theyโ€™re only made after you buy them.
