MAL-2026-11053 Malicious code in app-data-lts (npm)

package.json declares postinstall node test.js and main: index.js, but index.js is absent from the tarball. test.js executes require('.'), which throws immediately because the main module is missing, so the postinstall hook fails. README describes an unrelated 'ts-api' project, author metadata is empty, and dependencies include a package named child_process that name-squats the Node.js core module. No exfiltration, remote fetch, credential access, or executable payload is present in the shipped files. The shape is consistent with either a broken publish, a placeholder, or a staged release awaiting a payload in a future version, but as shipped the package has no code path that harms an installer.

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.
