mnhdjoweuqnpm
Advisory published Updated
mnhdjoweuq is a confirmed malicious npm package (MAL-2026-13822) that typosquats a legitimate package to trick installs (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in mnhdjoweuq (npm)
What this malware does
Package contains only package.json and index.html, with main pointing at the HTML file. index.html mimics a Cloudflare Turnstile 'Just a moment' challenge and contains an obfuscator.io-obfuscated Turnstile callback that reconstructs a URL starting with 'https://lo' from a string-array and navigates the browser to it via window.location. There are no install lifecycle scripts (preinstall/install/postinstall/prepare) and main is HTML rather than JavaScript, so nothing executes on npm install or require of the package. The obfuscated redirect only fires when a browser loads the HTML (for example if served via a CDN like unpkg/jsdelivr), affecting a browser visitor rather than the developer who installs the package.
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
TyposquatFind it
Search your lockfiles and build artifacts for mnhdjoweuq (version 1.0.0).
If you installed it — respond
mnhdjoweuq is a typosquat — you almost certainly intended a legitimately-named package. Remove mnhdjoweuq, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If mnhdjoweuq 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 mnhdjoweuq-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.
