mnzjgxciwadknpm
Advisory published Updated
mnzjgxciwadk is a confirmed malicious npm package (MAL-2026-13825) that executes malicious code on install (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in mnzjgxciwadk (npm)
What this malware does
The package contains a single file, index.html, which is also declared as the package main. The HTML presents a Cloudflare Turnstile-styled challenge page and, on completion, executes obfuscator.io-style JavaScript that constructs a URL against a *.olive.club host and navigates window.location to it, forwarding query-string parameters. There are no lifecycle scripts (preinstall/install/postinstall/prepare) and no JavaScript module entrypoint, so npm install and require()/import of this package do not execute the redirect code. The harm surface is a browser user who opens the HTML file, not a developer or build system that installs the package. This is registry abuse — hosting a phishing/redirect landing page inside an npm package — rather than a supply-chain attack against installers.
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.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for mnzjgxciwadk (version 1.0.0).
If you installed it — respond
Remove mnzjgxciwadk from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If mnzjgxciwadk was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks mnzjgxciwadk-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
