egypt0811npm
Advisory published Updated
egypt0811 is a confirmed malicious npm package (MAL-2026-13806) 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 egypt0811 (npm)
What this malware does
The package contains only index.html (declared as main) with no JavaScript modules, no lifecycle scripts (preinstall/install/postinstall), and no bin entries. The HTML is styled as a Cloudflare Turnstile 'Just a moment...' interstitial and contains an obfuscated inline script that reconstructs a destination URL beginning with 'https://eg' from a string-array and calls window.location.replace to redirect the visitor's browser, forwarding query parameters. Neither npm install nor Node require() of this package executes any code — HTML is not a Node module and no install-time hooks are declared. The redirect fires only if a browser opens the HTML file directly. This looks like registry abuse to host a phishing/redirect page rather than a supply-chain attack against developers who install 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
Malicious packageFind it
Search your lockfiles and build artifacts for egypt0811 (version 1.0.0).
If you installed it — respond
Remove egypt0811 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 egypt0811 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 egypt0811-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.
