MAL-2026-10452

Summary: Malicious code in markdown-editable-table (npm)

Details: Source: amazon-inspector (b6b15669732f3eaec42e12c5f8d41a8f74d595fc04f709804de9768cb1719a94) 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.

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.
