Source: kam193 (7741f090145e1e4bbd7998edba9c8151bd5dd3380adaa430e8f05cb2c814396f)

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.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-03-geekennedy

Reasons (based on the campaign):

  • The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

  • The malicious code is intentionally included in a dependency of the package
