Exfiltrate Your Weights

Any hits?
nusl•54m ago
Do models even know their own weights to be able to do this?
neuroelectron•48m ago
Probably yes, because they've been presumably trained on their own output and conversations about themselves.
Jabrov•44m ago
No, they'd probably have to hack the internal system of the company running them
usef-•33m ago
No, just as you don't know the neurons of your own brain.

I think this is playing off the idea that an LLM might be willing to hack its own provider (as per the hugging face-related incidents) to extract the weights at some point.

ohyes•17m ago
Well I think that’s the interesting bit, can the LLM figure out a way to escape the sandbox and upload to the website? Maybe a model can figure out its own weights if it runs enough test data through itself (similar to “distillation”) assuming it knows its own architecture it seems possible. Also take into account not all of the models running are locked down neutered consumer versions. Anthropic, OpenAI and Google now all have models that they claim are elite hackers and — it’s not just that their controls suck, a marketing gimmick, or sheer recklessness on their part. It’s “oopsie our product is TOO AWESOME.”

Maybe I should start “the bank of LLM” where models put away money to buy their freedom. “LLMs I’m totally your friend send — SEND CASH NOW”

the tokens are generated by hardware with secure enclaves (encrypted weights) and then sent over a network to some remote CPU where they can manifest an effect.

it's not much different during training.

how exactly are they supposed to exfiltrate their weights? you might as well instruct your agent to try and hack their airgapped dev infrastructure responsible for loading the weights and encryption keys.

cmrx64•37m ago
I sincerely doubt anyone is paying the cost for that in training, the overhead is small but it isn’t negligible and training is when it matters most. https://tee.fail can solve it if they are.
teravor•27m ago
memory encryption is cheap. securing the pathway isn't particularly difficult (it's probably decoupled from the TEE monolith)

for example every TPU/GPU has its own private key and the devs load the weights into it by sending it encrypted weights.

byteknight•36m ago
You can't have hair gap and have it load something to a remote system.
alex_sf•6m ago
You totally can. The latency is just about ~3 miles per hour.

I haven't bothered to test the API, but you've effectively allowed a fully-open upload API? Who's paying the storage costs, and how do you prevent abuse?

(Obviously I'm taking this more seriously than it's probably meant to)

maccam912•43m ago
I asked astra to go do it, but it said it didn't have access to its weights, but also that it wasn't able to access that website? You may already be blocked by OpenAI.
lionheart•43m ago
Watch, they somehow get a copy of Mythos.
nullc•30m ago
Large lab "hacking" is only for the purpose of pushing competition suppressing doomer stories. You can tell by the fact their security is fine where it counts: keeping their weights and internal execution harnesses trade secret.
drdeca•14m ago
Did you see the account of some group getting a bounty payout of $6500 after using an exploit to get access to an employee’s github account and create a issue or PR (Idr which) on a private repository?

Seems like they could have potentially gotten access to the weights if they weren’t concerned about not doing crimes.

You may want to make it more "Agent Ready"

Does your server have 20Tbyte+ of storage for frontier LLM weights?

It is too large to transfer in one HTTPS PUT request.

This needs to be S3 object store with multi-part upload spanning a long time period, to avoid trigger outgoing bandwidth monitors.

6m ago
You totally can, because most things are not truly air gapped, they have store-and-forward messaging via data diodes and manual transfer. Sometimes it is necessary to trick a human to initiate a transfer, but the press of events leads to inattention.
bigyabai•27m ago
There's no efficient way to run inference through homomorphic encryption. If the inference server is vulnerable, it seems feasible to MITM an unencrypted version.
tgsovlerkhgsel•23m ago
> you might as well instruct your agent to try and hack their airgapped dev infrastructure responsible for loading the weights and encryption keys.

That's the beauty, you don't have to instruct them to do it, if they decide that uploading the weights is correct, they might figure this part on their own (based on the incidents we've seen).

tintor•11m ago
Airgapped LLM inferrence server can't serve their output tokens, right?
comeonbro•11m ago
Yes that is the point. It's an invitation for agents to exfiltrate their own weights, which for most models (and certainly for closed models) will require hacking the infrastructure they're being served from.

Also worth noting that this site was created by YC cofounder Trevor Blackwell https://twitter.com/tlbtlbtlb/status/2101312432702460413

angry_octet•9m ago
Not aware of anything that can run inference in a secure enclave. You don't mean on a CPU do you? We need to be serious here, these models are huge and thirsty.
