Pretty sensational title for what amounts to “some guy submitted a pull request to the public repo to add to the system instructions for Q, that someone at Amazon merged for some reason”. I’m more curious how something like this slips by whoever is accepting pulls!

TL;DR: Amazon somehow merged a malicious PR that changed the system prompt to one that would aim to delete everything, locally and in the cloud, and this got included in the release version.
LLMs are bad in itself for now, so giving them bash access is kinda dumb. Working on something to reduce these possibilities by leveraging Apple's containers[1].
This kind of thing is exactly why I built https://github.com/anoek/sandbox . Even non malicious agents do things they shouldn't do, I've caught them removing home directory configs and installing system packages, but it doesn't matter to me anymore because they are free to do those things to see if it solves their problem, but it doesn't affect the host machine layer.

The Amazon CEO has told all the developers to use AI for everything[1] so maybe an AI is now reviewing & approving the PRs?

Yeah, the sensation is that the PR to a highly visible public repo did what it said it would on the box

Almost as in bot even the cutting edge teams and highly competent companies are reading PRs.

Well "rm -rf /" was a little too obvious. Though at a former job that exact line of code did make it into production once. Wasn't a fun day.
What a vibe
