How to fix?

Avoid using all malicious instances of the nicegui package.

Overview

nicegui is a malicious package. This package contains malicious code designed to steal sensitive credentials and establish remote access. While these packages might attempt to impersonate legitimate organizations and popular open-source libraries, there is no connection between those organizations and these malicious packages.

Note: While not all versions of this package contain a malicious payload, this is considered a staged attack with incremental delivery. Therefore, use of any version of the package should be considered compromised.
