Malicious package

alimama-minisitenpm

alimama-minisite is a confirmed malicious npm package (MAL-2026-15495) 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 alimama-minisite (npm)

MAL-2026-15495
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall alimama-minisite

What this malware does

package.json declares a self-named dependency alimama-minisite whose value is the off-registry URL https://repo.securityctrl.com/alimama-minisite instead of a semver range from the npm registry. On npm install, npm fetches whatever bytes that host returns and installs them, executing any lifecycle scripts contained in the fetched artifact. The dependency is unpinned and has no integrity check, so the returned content can change at any time. The dependency key equals the package's own name (dependency-confusion shape), and an implausibly high version (45.0.0) is set to win resolution against an internal package of the same name. The shipped index.js is an inert stub; the manifest line is the entire installer-side effect.

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.

Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for alimama-minisite (version 45.0.0).

  2. If you installed it — respond

    Remove alimama-minisite 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.

  3. Did it already run?

    If alimama-minisite 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.

Frequently asked questions

Detect & block this

O3 blocks alimama-minisite-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
