vlbhvgovbbhfabnpm

Advisory published Updated

vlbhvgovbbhfab is a confirmed malicious npm package (MAL-2026-13842) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in vlbhvgovbbhfab (npm)

MAL-2026-13842
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall vlbhvgovbbhfab

What this malware does

Package [email protected] contains 2 files. No install-time lifecycle scripts, exfiltration primitives, hardcoded network destinations, credential-file reads, obfuscated payloads, or dropper patterns were observed in the package contents. The random-looking name and minimal footprint are consistent with a placeholder or test publication rather than a functional library.

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 vlbhvgovbbhfab (version 1.0.0).

  2. If you installed it — respond

    vlbhvgovbbhfab 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 vlbhvgovbbhfab 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. vlbhvgovbbhfab on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
