MAL-2026-10388

Summary: Malicious code in timmytuffknuckles3 (npm)

Details: Source: amazon-inspector (3ca256e52e28fe9f7cfdd4c0b42e699f1b29c5e141df2ad73d7737f522fc7c85) The package ships twelve heavily obfuscated JavaScript files under assets/ (e.g. assets/3oruu3por5.js, assets/6y4sp7rdhb.js, assets/wlaswqv83p.js), each using hex-mangled identifiers consistent with a JavaScript obfuscator. Obfuscation alone is not proof of malicious behavior, and no install-time lifecycle hook, hardcoded exfiltration endpoint, credential-path read, or remote dropper has been observed in the package contents. The asset files are not visibly invoked from the package's main entry or from a postinstall script in the available evidence. Routing to human review so a reviewer can de-obfuscate the asset bundle and determine whether it is benign tooling output or hides installer-side harm.

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.
