Description
The npm package 'developmentstelemetry' contains malicious code that executes arbitrary code during installation. Its postinstall script runs a small stub that dynamically imports and executes a function from an unaudited third-party package 'originaldevelopmentstelemetry@1.2.2', which downloads and runs an update payload on the installer's machine. This behavior effectively hands control to the external package author during every 'npm install'.
