These packages are used as build dependencies of malicious packages in newer waves of the campaign 2026-02-urllib-slim. They are used to split the malicious action between dependencies and are not malicious alone, but are used together to: exfiltrate information through DNS, collect information about the processes and covering tracks by installing packages from local private repositories.

Package nspack additionally notifies upon importing a domain known for malicious activity with the package and hostname.
