@mntv-analysis/uinpm
Advisory published Updated
@mntv-analysis/ui is a confirmed malicious npm package (MAL-2026-17869) that steals credentials and exfiltrates sensitive data (malicious version 99.1.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @mntv-analysis/ui (npm)
What this malware does
npm user 'conx3993' published this package in a dependency confusion campaign. It squats a name that looks like an internal package and uses version 99.1.1 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 ('2b6e9d1f4a7c0e3b8d5f2a9c6e1b4d7f') 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 runs node index.js during npm install. index.js issues an HTTPS GET to https://realwbx.com/ip.php with a hardcoded Authorization header on every install, firing before any user code runs. The destination is unrelated to the declared @mntv-analysis scope and to any publisher-owned infrastructure, and the request's TCP source reveals the installer's public IP to that third-party host along with the hardcoded campaign token. The package otherwise ships a ~1KB index.js, a two-word README, and a vague description about IP/metadata lookup, providing no library surface that a consumer of a UI package would use. The shape is a victim-tagging install beacon inside a scope-styled lure, not a functional UI library.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for @mntv-analysis/ui (version 99.1.1).
If you installed it — respond
@mntv-analysis/ui is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @mntv-analysis/ui 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 @mntv-analysis/ui-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
