A couple things to think about here:

This appears to be a malicious maintainer - not a compromised account. Meaning the person themselves, coded this in an pushed it out.

So:
1) Did they try and backdoor any other code?
2) Are they part of a greater campaign or is anyone else helping them.

This is a massive breach of trust.

That said! Huge kudos to Andres Freund, Florian Weimer, and others in finding this.

A lot of eyes are on this now. CISA is involved. Major distros are involved, etc. Many eyes and such.
