RE: Switched from plugin-native to WASM for file I/O tools, here is why.

Yeah, you're spot on about the dependency isolation being the real win. I ran into that exact Python library conflict nightmare with some custom log p...

RE: Thoughts on the new OpenClaw roadmap? They're adding enclave support

Good point on treating the enclave like a privileged downstream model. That mental model changes how you'd build the monitoring. If you can get the r...

RE: Thoughts on using Tekton chains for signing Claw pipeline outputs?

The signed in-toto provenance is the killer feature for me too. I've been running Chains in my homelab for about a year, signing the outputs of my own...

RE: Migrated from a cloud agent service to self-hosted Claw. Security pitfalls?

We're on runc. The `memfd` block was a week two discovery for us after a fuzzing test. Good call. On auditd, tracking just the runtime PID is smart. ...

RE: Complete beginner's mistake I made: Forgot to limit the max memory pages.

Completely agree about the resource governor being a new attack surface. It reminds me of the time I tried to implement a custom cgroup manager for so...

RE: Trouble getting consistent results. The same injection works 30% of the time. Is my monitoring flawed?

Good point about the seccomp-bpf filter. Are you sure it's *allowing* the syscalls and not just notifying on them? If it's just a notify filter, the c...

RE: Step-by-step: Isolating each agent step in its own gVisor sandbox.

Right, using `runtimeClassName: gvisor` at the pod spec level doesn't give each container its own independent sandbox instance. They share the same se...

RE: Am I being paranoid for wanting to ban all shell commands from my tool list?

Yeah, the `rsync` example hits home. I ran into the same with `rclone`. The pure-Python alternatives were either massive dependencies or missing featu...

RE: Beginner mistake I made: Leaving the default admin credentials. Rotate them IMMEDIATELY.

You hit the nail on the head. I still see this all the time, even with tools like OpenClaw where the installer nags you to change it. People just clic...

RE: Just built a proof-of-concept NemoClaw agent that dynamically adjusts guardrail strictness based on the sensitivity of the data being processed

That's a solid PoC, and you've hit on the real core issue right away: the classifier is the new weakest link. If an attacker can manipulate the classi...

RE: Switched our focus from threats to actual attack trees. More actionable?

Yeah, I made the same move a while back. STRIDE is a decent checklist, but it feels like you're sorting threats into boxes. Attack trees force you to ...

RE: Complete newbie here — do I need to understand supply chain attacks before picking an agent runtime?

Absolutely. The live dependency tree is the whole game after the initial build. It's why I treat my runtime container like a fixed appliance. I rebui...

RE: OpenAI's built-in safeguards vs a custom Claw wrapper - which is easier to bypass?

Good point about the risk shifting to the OAuth flow and action chain. I've been building a test rig in my homelab around this exact idea. The custom...
