we pitted claude opus 5.5 against kimi k3 on pokémon emerald tasking each with finding novel 0-days
both built a link-cable worm that turns it into tetris, but took very different paths to get there

Welcome Graham O'Donnell to RunSybil as our newest Member of Technical Staff!
A friend described RunSybil to Graham as a place where “smart, talented people are doing cool work,” and he was IN. Graham believes security is a problem we can solve, and RunSybil gives him the chance to put that idea to the test.
He’ll work with Sybil on vulnerability research, explore what inference can do for security, and push toward securing the internet at machine speed.
Outside of work, Graham is into gravel biking, skiing, swimming, and just about any excuse to get outside. When he slows things down, he’s exploring traditional Chinese tea or hunting thrift stores and estate sales for rare books.
We’re happy to have you at RunSybil, Graham!

What does Application Security look like for a company that must protect the $5 trillion in equity it manages?
For @cartainc, working with RunSybil means continuous coverage of their attack surface, insight into novel attack vectors beyond known bug patterns, and remediation that matches the speed of development.

as sybilians we're proud to sign this letter
AI is rapidly changing the economics of offense. As the cost of finding and exploiting vulnerabilities trends toward zero, defenders can’t afford to operate at human speed.
@RunSybil is proud to stand with @OpenAI, @AnthropicAI, and others calling for stronger cyber defenses built for this new reality.
Finding vulnerabilities faster is only part of the problem. We need to make fixing them dramatically faster too by identifying the exposures that materially matter and driving remediation as fast as possible.

RunSybil has a new storyteller. Meet Sharon Gaudin, our Senior Technical Content Marketing Writer.
Sharon is a journalist who has written extensively about technology and science, including covering the first insider computer sabotage case in the U.S. Her first-ever interview? The Ramones. Not a bad way to start.
At RunSybil, Sharon will tell the stories behind what we’re building, share our customers’ successes, and bring clarity to complex security ideas.
When she’s not writing, you’ll probably find her adventuring with her dog, Addie, getting lost in a good book, or grabbing another coffee.
Welcome to RunSybil, Sharon!

We have a new Sybilian on the team! Welcome Kiwi Issa, our newest Member of Technical Staff.
Kiwi comes to RunSybil with a background in offensive embedded security research and AI security, bringing hands-on experience breaking, testing, and understanding complex systems.
Kiwi joined RunSybil because she believe we're approaching AI-powered security the right way, with the opportunity to dig into the kind of interesting security research that pushes both our product and the field forward.
Outside of work, Kiwi stays busy as a DEF CON Goon, FRC mentor, firedancer, hardware hacker, and DEF CON badge maker. She’s also a big fantasy and sci-fi fan, loves live music and raves, and spends plenty of time with Zuko and Kona, her certified pupners in crime.
Welcome to the team, Kiwi!
