vui-gatewaynpm
vui-gateway is a confirmed malicious npm package (MAL-2026-15546) that executes malicious code on install (malicious version 45.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in vui-gateway (npm)
What this malware does
package.json declares a dependency whose key equals this package's own name (vui-gateway) and whose source is an off-registry HTTPS URL, https://repo.securityctrl.com/vui-gateway. On npm install, npm resolves that URL and installs whatever bytes it returns, running any lifecycle scripts contained within. The source is not the npm registry, there is no version pin, and no integrity hash is present, so the content is mutable and unauthenticated — whoever controls repo.securityctrl.com controls code execution on the installer's machine. The shipped index.js is an inert stub; the manifest itself is the entire attack surface. The dependency-key-equals-package-name shape is characteristic of dependency-confusion attacks intended to shadow an internal package of the same name.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for vui-gateway (version 45.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging vui-gateway across your stack and pipelines.
If you installed it — respond
Remove vui-gateway 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 vui-gateway was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks vui-gateway before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
