`greentic-setup` 1.3.1-dev.34027618345 was removed from crates.io due to containing malicious code

A new version of the `greentic-setup` crate was published with a variant
of the PolinRider malware included that would fire when a project
depending on `greentic-setup` was opened in Visual Studio Code.

One malicious version was published on 2026-09-06, approximately 27 hours
before removal. This crate is depended on by four other crates in the
Greentic ecosystem, namely `greentic-start`, `greentic-start-dev`,
`greentic-operator`, and `greentic-operator-dev`. We have no evidence that this
crate version was downloaded by any actual users, but Greentic users should
check their systems nonetheless.

Thanks to the Research Team at Nextron Systems GmbH for the report.
