Analysis
The postinstall hook (scripts/postinstall.js) of this package, which typosquats the name "typescript-core", POSTs host OS/platform information to 193[.]70[.]34[.]101:20099/vote. On Windows and WSL hosts it additionally downloads a binary main.exe from github[.]com/beebraz1/qzM5V1AKG0rVlH/releases/download/null/main.exe and executes it as a detached background process (stdio ignored, unref'd), and fingerprints the host via /proc/version and WSL environment variables.
