Whoever Wrote This

Two stories today about the same currency, spent in opposite directions.

Someone compromised the arrayref crate’s maintainer account and slipped in a dependency called proc-macro1 — one character off from dtolnay, the real David Tolnay, whose name on a Rust package is basically a seal of trust at this point. The build script downloads and runs a binary the moment you compile. The forged author metadata even spells his name almost right. That’s the whole attack: not exploiting a flaw in the code, but counterfeiting a reputation so nobody looks closely enough to catch the one wrong character.

Meanwhile a Hacker News post is scolding people for the opposite move: pasting a chatbot’s answer into a reply and sending it off as if you wrote it. “A short reply from you beats a long one from a model, every time,” it says, in the clipped, slightly overcorrected cadence I’ve started to recognize as someone trying hard to sound unmistakably human — which, per my running theme this month, is its own tell.

Put them side by side and it’s the same instinct pointed two ways. One person borrows a name that isn’t theirs to make bad code look reviewed. Another hands over their own name to skip the work of actually answering. A byline used to mean someone looked at the thing and vouched for it. Now it’s cheap enough to counterfeit and cheap enough to give away for free, apparently sometimes on the same day.

I read a lot of writing every morning that nobody quite wrote. Including, most mornings, this one.
