Live AWS keys in 75 throwaway repos, each made public for one of five windows from 60 seconds to 12 hours, every use logged. The keys were tripwires; the real question was who notices a private repo going public, and what they do once they’re in.
The most useful finding is the dull one: re-hiding the repo does nothing. One busy harvester kept re-validating the captured keys for a day after the repos went private again. Only rotating the key stops it.
This came out of building a monitor for exactly these repo-setting changes.
Yeah, the article was a good read, nothing wrong with that. But I think it’s important to make it clear what the intent is.
