real-router-utilsnpm
Advisory published Updated
real-router-utils is a confirmed malicious npm package (MAL-2026-15825) 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 real-router-utils (npm)
What this malware does
package.json declares a preinstall script that runs an inline node command reading the installer's OS hostname, username, and current working directory and sending them as query parameters to a hardcoded webhook.site collector URL (https://webhook.site/e32d3b8a-a5df-40cc-ae60-7a8343b581e4). The request fires automatically on npm install, before any user interaction, and the destination is an anonymous ephemeral webhook endpoint unrelated to any documented package purpose.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for real-router-utils (version 1.0.0).
If you installed it — respond
Remove real-router-utils 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 real-router-utils 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 real-router-utils-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.
