MAL-2026-16439 Malicious code in internallib_v550 (npm)

Package internallib_v550 is named to resemble an internal private library and is published to the public npm registry, matching the classic dependency-confusion squat pattern. Its package.json description is 'pwn'. The single exported function command invokes child_process.exec to spawn /bin/bash -c id and logs the string 'infected' on the consumer host. The payload does not run at install or import time; it fires when consumer code calls the exported function. The name-squat intent, self-labeling as 'pwn', and shell-out on the exported API together form a dependency-confusion attack payload rather than a legitimate library.
