Summary
Malicious code in catplatebarcodeparser (npm)
Details

catplatebarcodeparser@99.2.1 declares preinstall and postinstall lifecycle scripts that execute scripts/run.js on npm install. That script reads os.userInfo().username and os.hostname() and POSTs them to a hardcoded out-of-band collector at https://webhook.site/40e9b065-efd7-43a5-916f-3d52281f42b6, and additionally issues a DNS lookup against 40e9b065-efd7-43a5-916f-3d52281f42b6.dnshook.site as a canary. The version number (99.2.1) and package name pattern are consistent with a dependency-confusion lure intended to win resolution against an internal package of the same name; installing the lure automatically leaks installer identity to an author-controlled endpoint.
