Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall pypi-package-explore

What this malware does

Package presents an extremely deep obfuscation of a code that is imported during installation. The exact behavior is unknown, but it includes loading encrypted code and interrupting debugging attempts

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

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 pypi-package-explore (7 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging pypi-package-explore across your stack and pipelines.

  2. If you installed it — respond

    pypi-package-explore 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 pypi-package-explore 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 pypi-package-explore 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

No. pypi-package-explore on PyPI has been identified as a malicious package (versions 0.0.1a0, 0.0.2a0, 0.0.3a0, 0.0.4a1, 0.0.4a2, 0.0.4a3, 0.0.4a4 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
