Advisory published Updated

Malicious code in pytablute (PyPI)

MAL-2026-13685
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall pytablute

What this malware does

Packages contain hidden code that is effectively run during importing or using the library, and downloads second stage code. Then, a process running in background periodically connects to a remote host and waits for next code to execute

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2025-11-spellcheckers

Reasons (based on the campaign):

  • obfuscation

  • Downloads and executes a remote malicious script.

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for pytablute (version 1.0.3).

  2. If you installed it — respond

    pytablute 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 pytablute 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. pytablute on PyPI has been identified as a malicious package (version 1.0.3 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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