It appeared to be typosquatting existing crate
polymarket-client-sdk (polymarkets vs
polymarket) and attempting to steal credentials from local files.
The malicious crate had 1 version published on 2026-02-19 an hour before removal and hadn't been downloaded. There were no crates depending on this crate on crates.io.
Thanks to Carol Nichols, who is thanking herself for spotting this in the docs.rs build queue and removing it quickly!
