markdown-editable-table @2.4.4

Summary

The package's package.json declares a preinstall hook ( node index.d.js ) that runs automatically on npm install . The script in index.d.js base64-decodes a payload whose decoded body fetches JavaScript from https://everydaynodechecker-39143n.vercel.app/api/key?mem=root1 and passes the response to eval . Both the destination URL (hidden inside a base64 blob) and the eval identifier (reassembled from the char-code array [101,118,97,108] via String.fromCharCode and invoked as globalThis[tag](text) ) are obfuscated. The package metadata (repository wooorm/markdown-table , description, funding) impersonates the legitimate markdown-table package while shipping unrelated code, indicating a typosquat lure. Installing the package results in arbitrary attacker-controlled JavaScript executing on the installer's machine.
