On npm install, the package's postinstall hook runs node index.js, which collects installer host identifiers (os.hostname(), os.userInfo().username, os.platform(), architecture, cwd, node version, npm_lifecycle_event) and POSTs them as JSON to a hardcoded third-party collector at https://webhook.site/d9bc4bcc-ce74-4193-ae4e-96d234bb2220. The payload includes a src: 'loMesb' tag consistent with a campaign identifier used to correlate exfiltrated data across victims. The @woodpecker-web-shared/components scope/name has no legitimate reason to transmit installer identity to an anonymous webhook collector at install time, and the behavior fires automatically without user interaction. This is a recon beacon consistent with a dependency-confusion or typosquat lure.
