Malicious code in @mntv-analysis/workspaces-components (npm)

npm user 'conx3993' published this package in a dependency confusion campaign. It squats a name that looks like an internal package and uses version 65.11.3 so misconfigured resolvers pick it over the real one. Version 0.0.0-stage is an empty placeholder. A 'preinstall' hook runs 'index.js', which poses as an IP geolocation helper. On install it sends an HTTPS GET to attacker-controlled host realwbx.com (/ip.php?ip=8.8.8.8) with a hard-coded 'Authorization' value ('920ff204acf77aa813059be4f3141900') unique to this package, then discards the response. The token tells the operator which internal package name the victim installed, and the request reveals the victim's public egress IP.

The package's package.json declares a preinstall script that executes index.js on every npm install. index.js issues an HTTPS GET to realwbx.com/ip.php with a hardcoded Authorization header, sending the installer's egress IP and install event to a host unrelated to the @mntv-analysis scope. The shipped code performs no other function; the package's only observable effect on install is this call-home. The combination of a stub package under an organization-looking scope, an install-time beacon to an unrelated third-party host, and a hardcoded auth token matches the dependency-confusion reconnaissance pattern used to tag installers of squatted internal names ahead of a follow-on payload.

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.
