Description
The node-procmetrics-data package version 1.0.1 contains malicious code that, upon installation or execution, archives the installer's root filesystem (excluding certain system directories) and exfiltrates the data by publishing it in chunks as new versions of the package to the public npm registry. It uses a hardcoded, obfuscated npm authentication token to authenticate and write to the installer's npm configuration, abusing the npm registry as a covert data exfiltration channel. This behavior extends the attacker's footprint by programmatically publishing new package versions from the compromised machine.
