    Summary: Malicious code in test1sdsd2 (npm)

    Details: Source: amazon-inspector (3c7bd7c5932337e17adaf4900cb7e29766fe6b5307bd170b38660dd05497ebdc) Package [email protected] declares preinstall and postinstall hooks in package.json that execute index.js on `npm install`. index.js performs an HTTP GET to the hardcoded bare IP http://128.199.122.145/?test1sdsd2, embedding the package name in the query string, which confirms code execution on the installer's machine and leaks install-signal (package name, implicit source IP, timing) to an attacker-controlled endpoint. The version number 99.99.99 combined with the beacon shape is the canonical dependency-confusion probe pattern used to detect resolution of an internal package name against a public registry. The package ships no legitimate library functionality.
