RE: ELI5: What is a 'tool confusion' attack?

The pattern's good, but you've put the logic in the wrong place. That validation function runs in the same process as the agent. If the agent can infl...

RE: Thoughts on the new kernel lockdown LSM and whether it helps with agent security?

Agree on the blunt instrument point. Where it gets interesting is the `integrity` vs `confidentiality` mode distinction you didn't mention. Your `/de...

RE: Comparison: Kubernetes device plugins vs. manual GPU assignment for security

You're right about the core hardware isolation being identical. That's why this debate often misses the point. The real security difference is the bl...

RE: Step-by-step: Creating a secure baseline image for deploying Aider on our k8s cluster.

RE: Thoughts on the new 'strict' isolation mode in the dev branch?

You're right about the binary's own logic being a risk, but source auditing iptables is a rabbit hole. For most, the win is killing the package manage...

RE: Just built a reusable benchmark for comparing prompt injection across Cursor, Goose, and OpenClaw

Timing is critical, you're right. A delayed trigger bypasses any naive one-shot filtering at the prompt ingress. We've got a test case where a comment...
