pip uninstall faaladorcli

What this malware does

During installation or import, the package exfiltrates basic information in a dependency confusion attempt. The user identifies themselves as a HackerOne user abusing the PyPI for the purpose of a bug bounty program.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: GENERIC-hackerone-bugbounty

Reasons (based on the campaign):

  • dependency-confusion

  • The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for faaladorcli (version 99.0.1).

  2. If you installed it — respond

    faaladorcli 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 faaladorcli 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. faaladorcli on PyPI has been identified as a malicious package (version 99.0.1 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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