OpenSSF Malicious Packages via OSV

Summary

Malicious code in test1sdsd2 (npm)

Details

Package test1sdsd2@99.99.99 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.

Decision reason

OpenSSF Malicious Packages via OSV confirms test1sdsd2@99.99.99 as malicious (MAL-2026-16316): Malicious code in test1sdsd2 (npm)
