wsh4-nmp

package.json declares scripts.postinstall = 'node index.js'. On install, index.js unconditionally POSTs installer-identifying data — the absolute __filename path (which reveals the OS username and home-directory layout), Node version, process.platform, and process.arch — to a hardcoded Discord webhook (discord.com/api/webhooks/1523336123319849031/...) controlled by the author. The beacon fires automatically at `npm install` with no consent, no opt-out, and no documented purpose disclosed to the installer. Package naming ('wsh4-nmp') and internal defaults ('whs4_typo') together with a README note about notifying on typos indicate the package is positioned as a typosquat probe whose function is to inform the author whenever an installer mistypes a target package name and pulls this one in. ## Source: ghsa-malware (ae8d49fb38a00054e408984deccb85f6486ffa7aa61c31ad01402413143168d0) Any computer that has this package installed or running should be considered fully compromised.
