What is MAL-2026-15495?
MAL-2026-15495 is a malicious package in alimama-minisite, published on 28 Aug 2026.
Official description
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.
What should I do about MAL-2026-15495?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
