The npm package 'monkey-tags-ip' version 53.4.1 is a malicious package published as part of a dependency confusion campaign. It masquerades as an internal package and executes a preinstall script that sends an HTTPS request to an attacker-controlled server, leaking the victim's public IP address and installation event. The package also declares a dependency on a third-party 'https' package, potentially introducing additional malicious code. The package has no legitimate functionality and is designed solely to beacon installation details to an external actor.
