Description
The npm package 'abuden21' version 1.7.7 is identified as malicious due to namespace squatting behavior. It repackages the same payload under approximately 90 unrelated package names to pollute the npm namespace and potentially capture traffic or typo-based installs. The payload is a browser single-page application that opens a monetized popunder on user interaction but does not execute code during installation or require hooks that run on install. There is no evidence of credential theft, remote code execution, or direct system compromise from installing or requiring the package. However, the mass republishing and namespace abuse pose a supply chain risk and may mislead users. The package should be removed if installed, and secrets rotated as a precaution, although no direct exploitation is confirmed.
