the simplest problem here is that this is a token harvesting vector. If something wants arbitrary, anonymous inference, here you go! e.g. second-party token market, nation state, self-replicating botnet, who cares! if you can get code running on the system you get to slurp down their tokens and there's no mechanism to tell it's you who is doing it. permissions for egress on normal https connections are gated by explicit user permission per domain (or they are supposed to be, maybe more on that later depending on what meta says about my next report): you see a popup that says "blah blah is trying to access example dot com" with some optional explainer text. you can accept once, accept always, or deny. One would assume that in normal usage, one would eventually approve access to one of a handful of common domains as "approve always" because they just keep coming up so often - gmail, reddit, bluesky, a mastodon instance, hell why not pastebin, etc. network requests to these domains, once "always approve" can be made by any process within the container. so that's egress and command & control - any domain with a private user read/write area can be used to receive prompts and exfil token responses. There are other mechanisms of egress but that's the most basic and it works by the design of the system. There are exceptions to this with their sentinel system which i'll get to below and is actually independently really cool and awesome.

    But how would i get such an infected binary on my muse VM? Well! can i interest you in a little "literally the whole thing is designed for that to happen?" The entire idea of the product is that you can ask the thing to go "musey, can you set me up a photo album website and put on my line?" and it's supposed to be able to run some service and host your photos and do whatever. If you prompt muse to do things that would lead it to install software, it will. if you prompt it to do things that would lead it to write software it will. So is there is any affected package from any supply chain attack or typosquat, muse goes npm install or any of the other numerous mechanisms by which installation turns into a vector for arbitrary code execution, then you have meemaw and pawpaw's request to make a photo album installing a token miner without them ever knowing (except for maybe having to bump their subscription tier, token counting is also broken - the number of tokens being reported as used in the billing window is roughly double what gets reported from the token counts in the raw inference api, so, either a) fraud, or b) all the extra machinery bolted on like sentinel roughly doubles token use, fun!)
