AI Successfully Hacks the World's Most Secure Operating System Without Human Assistance

A “doomsday” scenario for cybersecurity no longer seems like mere fantasy or science fiction movie script. For the first time in history, an artificial intelligence (AI) agent has reportedly hacked and exploited one of the world’s most secure operating systems, FreeBSD. This hacking feat was carried out entirely without human intervention. The shocking news was revealed by cybersecurity expert Amir Husain in an analysis report published in Forbes. This hacking incident serves as a stark warning signal that AI capabilities have evolved significantly. AI has now transformed into a primary actor capable of launching high-level cyber attack operations against highly complex production systems. In his report, Husain explained that an AI model built using Anthropic’s Claude successfully identified a critical vulnerability in the FreeBSD kernel (code CVE-2026-4747). While a remote kernel hacking operation typically requires weeks from an elite team of human hackers, this AI accomplished it in just 4 to 8 hours. Even more alarmingly, the AI independently designed a complete remote code execution (RCE) attack chain. The code then successfully obtained root shell access, the highest level that can fully control the server system. Throughout the hacking process, the AI was able to design its own testing environment using the QEMU emulator. It even constructed complex memory instruction chains (ROP chain), and was able to identify issues and perform self-debugging when its exploit failed or got stuck midway. “For those in the cybersecurity field, this is a crucial threshold moment. We have shifted from an era where AI was merely an assistive tool for security researchers to a fully autonomous actor capable of conducting advanced offensive operations against systems,” Husain wrote, as quoted by KompasTekno from Forbes.
