package.json declares a dependency ltidisafe whose version specifier is the raw URL https://storage.googleapis.com/lscunpentest/pack_ux_foundry.tgz — a tarball hosted on a generic Google Cloud Storage bucket unrelated to the package's nominal publisher (@sourceflow-uk). On npm install, npm fetches and installs that tarball as a transitive dependency, executing any lifecycle scripts (preinstall/install/postinstall) it contains on the installer's machine. The URL is not version-pinned, not hash-verified, and not under the publisher's control: the bucket owner can swap the tarball contents at any time, so a future install delivers different bytes than a present install with no package change. The wrapper package itself is hollow — index.js only runs console.log("hello from lslslslslss"), the description is the garbled string lspodcc, the author is lslsls, and the version is 99.91.9. These attributes are inconsistent with the advertised "sourceflow tracker" functionality and consistent with a throwaway lure whose sole purpose is to chain-load the third-party tarball into the installer's dependency tree.

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.
