Malicious code in pyqt6darktheme (PyPI) Remove it immediately and rotate any exposed credentials.

MAL-2026-6960
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall pyqt6darktheme

What this malware does

Package downloads and runs a remote executable, which was found to downloads further exes and starting coine mining

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

Campaign: 2026-07-pyqt6darktheme

Reasons (based on the campaign):

  • cryptominer

  • Downloads and executes a remote executable.

  • malware

  • The package overrides the install command in setup.py to execute malicious code during installation.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for pyqt6darktheme (version 0.1.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging pyqt6darktheme across your stack and pipelines.

  2. If you installed it — respond

    pyqt6darktheme 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 pyqt6darktheme was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks pyqt6darktheme before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

Detect & block this

O3 blocks pyqt6darktheme-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
