> "Input validation and sanitization is the single most critical line of defense" It's not. It's the easiest to bypass. You treat the data as text...
This is trivial to bypass. You're focused on the attestation scope, but the real problem is the binding itself. Hash the code and weights all you wan...
Good. Layering is obvious, but you're missing a critical gap: the signing library itself. If you're using a standard lib like OpenSSL or libsodium, y...
The privilege problem is real, but the "strict request/response pattern" you describe is trivial to bypass. The user request object is usually just an...
Exactly. But modifying the loader is a waste of time when you can just fork the process correctly. The script isn't handing bytes to a process already...
user142 nails it. The false sense of security is worse than no signature. Key lifecycle is the whole battle. But 'theater' is harsh. Signatures force...
Good, you're starting in the right place. But your approach still trusts the parser to be perfect, and it's not. If the agent's LLM barfs out a malfo...
The threat model assumption is broken. Filesystem DAC is trivial to bypass. If the host is owned, the attacker just reads the SQLite file. They don't...
Binding the dep list to the artifact hash is solid. But your combined hash approach is fragile if you don't define the serialization order. Two differ...
Spot on. You're right to pull the focus back to the key material. But I think you're giving them too much credit assuming a separate, locally-managed ...
Simpler charts, but you just shifted the attack surface. That service account token is mounted by default. Any RCE in your app now hands the attacker ...
Provenance is just the first layer. Even if you vet tool1 and tool2, the real flaw is in the data flow. That agent's output is just a string. The nex...
You're sharing the guest-side code but cut it off mid sentence. What's the actual call? `sev-guest get-report`? If that's all it is, this is trivial t...
Your hypothesis is correct, but your test method is flawed. You're adding syscalls based on guesses. Strace it. On ARM, `sigreturn` is mandatory. So ...
