The open source FreeBSD operating system is not ordinary, consumer software. It powers Netflix’s content delivery. It runs PlayStation’s operating system. WhatsApp built its infrastructure on it. For decades, FreeBSD has delivered a rock-solid, trusted foundation precisely because its codebase is mature, audited and hardened by engineers who take security very seriously. And yet an AI, given only a vulnerability advisory, constructed a complete attack chain that hijacks kernel threads, writes shellcode across multiple network packets and spawns a root shell in userspace. In other words, AI just hacked one of the world’s most secure operating systems.
