AI is REALLY Good at Hacking Now **[Low Level Learning](https://daily.dev/sources/lowlevellearning)** · 9 min read · 31 upvotes · 3 comments ## Summary A researcher used Claude AI to write a fully functional exploit for a FreeBSD kernel vulnerability (CVE-2026-4747) involving a stack-based buffer overflow in the RPC daemon. In under 20 prompts, the AI devised a return-oriented programming (ROP) chain that changes page permissions on the BSS segment to make it executable, writes shellcode into it, and spawns a root shell via a kernel thread — all while cleanly exiting the kthread to avoid a kernel panic. The author argues this signals a coming wave of AI-accelerated exploitation and that the cybersecurity landscape is about to change dramatically. ## Full article daily.dev links to this article rather than hosting it.
