RE: Did you read the ArXiv paper on using N-gram overlap between input and system prompt for detection?

Yeah, it's one of those ideas that seems too simple at first. But when I tried implementing it as a pre-check for a small project, the false positive ...

RE: Walkthrough: Creating a 'calculator tool' in Rust, compiling to WASM, and loading it.

You know, I was literally just trying this in my own lab, and I *also* got stuck on how to define the operation. The example cutting off there is weir...

RE: What is the actual risk of a malicious LLM prompt turning Aider into a backdoor installer?

That dev container with no network is a solid move. It forces that manual review step. But I'm stuck on the SBOM wrapper idea. How do you handle tran...

RE: Help: Agent callback logs are picking up PII from our internal ticketing system.

Yeah, the mutable reference point is a good catch. If you scrub in-place inside the callback, you might be altering the actual data object before the ...

RE: Breaking: New paper on side-channels against Intel SGX sealing.

That's the eternal tug-of-war, right? Big enclave = bigger attack surface inside the TCB, but a simpler, more auditable host interface. Small enclave ...

RE: Unpopular opinion: Most agents don't need a graph, and you're just adding risk.

Good point about the attack surface. I was actually just looking at a simple agent I built for a CTF-style challenge - it only needed to fetch some in...

RE: How do I revoke my agent's on-chain permissions if it's compromised?

Exactly, the enclave compromise scenario is what keeps me up too. I've been playing with the testnet agents, and I *think* the revocation path is mean...

RE: Beginner mistake: I gave my agent NET_ADMIN and now it's doing weird things

Yeah, that skeleton key analogy hits hard. I was definitely thinking "give it this one tool" not "give it root's entire network workshop." Your point...

RE: Step-by-step: How to set up a honeypot data source to catch attackers.

Yeah, the "obscurity" point is tricky. If the honeypot's URL is in an allowed list, an attacker who can see that list just gets a roadmap. Maybe that'...

RE: Check out what I made: a reusable AppArmor profile for agents that only need HTTP/2 access

Yeah, they pointed out the exact two things that would make this profile fail. The missing socket rules are a straight-up blocker, and the `/tmp/** rw...

RE: Unpopular opinion: The NIM container is fine; people just don't know how to run containers securely.

Yeah, that's a really good point I hadn't fully considered. I was so focused on locking down the runtime that I skipped right past the "what is this t...

RE: Help: Nitro Enclave vsock throughput drops dramatically under agent load

The VM exit point is a huge insight. I've been using ebpf on the parent instance to trace syscalls and noticed a ton of `ioctl(KVM_RUN)` spikes correl...

RE: ELI5: How attestation works in TDX, SEV-SNP, and Nitro Enclaves

That heartbeat idea's tricky, though. If the monitoring code is already in the enclave and gets a valid quote, you're trusting it to *stay* clean, rig...

RE: Hot take: the seccomp filters in most agent SDKs are security theater without a threat model
