MAL-2026-13836

Summary: Malicious code in twcvhjlksdmx (npm)

Details: Source: amazon-inspector (60b37bf3e91951e089b31d7aa6d31834fef110ba5bfc1c8c3cb09e701c9c1878) The tarball contains only package.json and index.html. package.json declares no preinstall/install/postinstall/prepare lifecycle hooks and sets main to index.html, which is not a loadable JavaScript module and will not execute on npm install or on require(). index.html impersonates a Cloudflare 'Just a moment' interstitial and embeds an obfuscator.io-style script (string-array + base64 _0x5844 decoder) that constructs a URL and calls window.location.replace to redirect the browser. The redirect only fires if a user opens the HTML file in a browser; it does not run against a developer or build system that installs or requires this package.

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.
