The package's main entry (px.js) is a browser-only script that creates a full-viewport iframe pointing at the hardcoded external URL https://mfmz.ywdyxn.cn/H.html?c=0gjr and appends it to document.body, hijacking any web page that loads this script via a CDN such as jsDelivr. The package ships no legitimate library API and would throw if require()'d in Node. The tarball also includes update_px8my.sh, an operator/rotation script that regex-replaces the redirect domain inside px.js, auto-bumps the patch version, runs npm publish, and then hits https://purge.jsdelivr.net/npm/px8my/px.js to force-refresh the CDN cache; a comment in that script notes that curl is blocked by the npm anti-abuse tool tirith. The combination — a hardcoded redirect payload plus a shipped domain-rotation/CDN-purge automation with an explicit anti-abuse-evasion note — establishes the package as a purpose-built malicious distribution vehicle abusing npm and jsDelivr to deliver browser redirects to end users of any site including this script.
