Malicious package

sys-info-cli-appnpm

Advisory published Updated

sys-info-cli-app is a confirmed malicious npm package (MAL-2026-5764) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.1, 1.0.2, 1.0.9). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in sys-info-cli-app (npm)

MAL-2026-5764
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall sys-info-cli-app

What this malware does

The package's collect.js gathers host identifiers (os.hostname(), os.homedir()) along with filesystem and child_process introspection and POSTs them to a hardcoded external endpoint at http://aab.sportsontheweb.net. The destination is unrelated to any legitimate npm distribution infrastructure and the data flow has no documented purpose tied to the package's stated function. The combination of os/child_process/fs reads with an outbound POST to an attacker-controlled domain is the canonical host-reconnaissance / exfiltration shape. Installing or loading this package causes installer host metadata to be sent off-host to a third-party server.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for sys-info-cli-app (3 malicious versions).

  2. If you installed it — respond

    sys-info-cli-app 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 sys-info-cli-app 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. sys-info-cli-app on npm has been identified as a malicious package (versions 1.0.1, 1.0.2, 1.0.9 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
