egair0810npm
Advisory published Updated
egair0810 is a confirmed malicious npm package (MAL-2026-13805) that executes malicious code on install (malicious versions 1.0.0, 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in egair0810 (npm)
What this malware does
The package contains a single index.html file declared as the package main, presenting a fake 'Just a moment...' / Cloudflare Turnstile page with heavily obfuscated JavaScript (string-array + shuffling style) that constructs a target URL from encoded strings and calls window.location.replace to redirect the browser. package.json declares no preinstall, install, postinstall, or prepare lifecycle scripts, and main points at an HTML file that Node cannot load as a module, so npm install and require() of the package do not execute the obfuscated code. The payload only runs if the HTML is opened in a browser. The artifact is not a functioning npm library and appears to be registry abuse hosting a browser-facing redirect/phishing lure 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 egair0810 (2 malicious versions).
If you installed it — respond
Remove egair0810 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 egair0810 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 egair0810-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.
