A critical CPython CVE today took less than 45 minutes of human work to find, triage, and fix because of Xint Code

While code is abundant, assurance is scarce. The winners won't be the teams that generate the most code, it’ll be the teams that can prove it's safe.

Even secure-looking code can hide dangerous flaws. Learn why business logic vulnerabilities are hard to detect and why most scanners miss them.

Real Vulnerabilities. Actionable Results.

How we learned to build effective LLM agents for hacking at DARPA's AI Cyber Challenge (AIxCC)

An introduction to DARPA's AI Cyber Challnge and Theori's third place cyber reasoning system

Agent trajectory walkthroughs of a fully autonomous hacking system

In this article, we briefly look at the circumstances of the Bybit incident and discuss what countermeasures could have been implemented. Then, we discuss the limitations of current solutions and how Xint resolves them.

Security silos occur when different security tools, teams, or systems operate in isolation, unable to effectively share data or communicate.

Dive into five significant security risks that emerged as unintended consequences of new feature development.

So you know what ASM is and why you need it — but which features are crucial? Here’s the run down.

How LLMs are changing the game for static analysis — especially when source code is available.

Applications of larage language models in offensive security

Theori’s Cyber Reasoning System (CRS) “Robo Duck” not only cleared the bar to get us $2M and a spot at the AIxCC finals in 2025, it also got the first place among all the submissions in the highly competitive event.
