Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% 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. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. \#\# Source: ossf-package-analysis (e7eb1e1d0cace271eb14fb5f939e271fbe915ec9edd4413c85367c79296532ee) The OpenSSF Package Analysis project identified 'wsh4-nmp' @ 1.0.0 (npm) as malicious.
