## Source: amazon-inspector (c9c95dc5aea7805ca50e114bae45747a46edb7331311044b0d3730e303d4351a)
Package declares both preinstall and postinstall lifecycle hooks that execute index.js on `npm install`. index.js issues an HTTP GET to the hardcoded bare IP 128.199.122.145 over plain HTTP, embedding the package name in the query string (`http://128.199.122.145/?test1hh235`). Manifest shape is consistent with a dependency-confusion reconnaissance probe: version 99.99.99 (implausibly high to win resolution against an internal package), empty description, and a typo-prone name. The beacon fires automatically during install and signals successful resolution/installation to an attacker-controlled host, confirming the target environment for follow-on attack.
