MAL-2026-11015

Summary: Malicious code in react-tabulix-query (npm)

Details: Source: amazon-inspector (413e61124e5f46f550114ce54d841c1dc68b4dc3a9d0939c8f3c021a6c790a65) The package's package.json preinstall script runs dist/index.d.js, which base64-decodes an embedded payload and executes it. The decoded payload uses fetch() to retrieve code from https://everydaynodechecker-39143n.vercel.app/api/key?mem=root0 and passes the response body to eval, granting the remote endpoint arbitrary code execution on the installer's machine at npm install time. The eval identifier is reconstructed from a char-code array ([101,118,97,108]) and invoked via globalThis[tag](text) to hide the sink from naive scanners. The filename index.d.js mimics a TypeScript declaration file to further disguise the dropper. There is no legitimate library functionality; the package's only observable behavior is the remote fetch-and-execute.

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.
