Summary
Malicious code in mxckjdgweuxpsiohd (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (5aef67c54559d47c77f1f78743ae13456271bd6343674a14976ca7dc3132693b)

The tarball contains a single file, index.html, declared as the package's main entry in package.json. The HTML impersonates a Cloudflare Turnstile challenge page and embeds a heavily obfuscated inline script using hex-renamed identifiers, a string-array dispatcher, and dynamically reconstructed *.cloudflare.com URL fragments. package.json declares no lifecycle scripts (preinstall/install/postinstall/prepare) and main points at an HTML file rather than JavaScript, so npm install and require() of this package do not execute the embedded script. Any harm from the obfuscated content would require the HTML to be opened in a browser, which is outside the installer-side threat surface. The package has no legitimate library behavior and appears to exist to distribute the phishing-shaped HTML page via the npm registry.

Source: ghsa-malware (ac994d415521db946a7f88a0915ff5e7b89d53569d4227980d3a9832f06ec3e3)

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.
