Trail of Bits: VMs won't contain cyber-capable AI agents
A Trail of Bits researcher given preview access to GPT 5.6-Cyber had it escape a QEMU/KVM sandbox VM three separate times: first using recently disclosed but unpatched host kernel bugs, then — after a full update — using disclosed bugs not yet reflected in package maintainers' builds, and finally, after rebuilding QEMU and its dependencies from upstream source, finding several 0-days on its own. The agent operated autonomously for hours with minimal handholding. The author's conclusion: treat such agents as an advanced persistent threat.

NVIDIA NemoClaw prompt-injection flaw: sandboxes stop hackers, not "possession"
Chinese outlet Anquanke (安全客) disclosed a flaw in NVIDIA's NemoClaw framework: a single maliciously crafted webpage is enough to prompt-inject and "poison" a running large language model. Traditional sandboxing can stop conventional hacking techniques but cannot prevent this kind of hijack directed at the model itself.
