What this malware does

Part of a dependency confusion attack campaign targeting the @cloudplatform-single-spa and @mlspace npm scopes. The attacker (npm user mr.4nd3r50n) published 139 scoped packages at the inflated version 99.99.99, which resolves ahead of any private registry version via npm's default version resolution, silently hijacking installs of internal packages.

This specific package carries no active postinstall payload and its description claims "BugBounty testing". However, it squats a legitimate internal package namespace at an inflated version as part of the broader campaign.

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 @cloudplatform-single-spa/logaas (all published versions).

  2. If you installed it — respond

    Remove @cloudplatform-single-spa/logaas 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 @cloudplatform-single-spa/logaas 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

No. @cloudplatform-single-spa/logaas on npm has been identified as a malicious package (all published versions flagged). It should be removed immediately — do not install or keep it in your dependency tree.
