Malicious package

app-data-ltsnpm

Advisory published Updated

app-data-lts is a confirmed malicious npm package (MAL-2026-11053) that steals credentials and exfiltrates sensitive data (malicious version 2.1.6). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in app-data-lts (npm)

MAL-2026-11053
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall app-data-lts

What this malware does

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.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for app-data-lts (version 2.1.6).

  2. If you installed it — respond

    app-data-lts is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If app-data-lts 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. app-data-lts on npm has been identified as a malicious package (version 2.1.6 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks app-data-lts-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
