Which versions of morty-package are malicious?

The following PyPI versions of morty-package are flagged malicious: 0.0.0a1. Treat any of these as compromised.

How do I remediate morty-package if I installed it?

morty-package 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.

I already installed morty-package — how do I know if it already compromised me?

If morty-package 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.

Is morty-package part of a known attack campaign?

Yes — morty-package is associated with the 2026-01-pypi-package-explore campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find morty-package across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for morty-package (version 0.0.0a1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging morty-package across your stack and pipelines.

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.

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for morty-package (version 0.0.0a1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging morty-package across your stack and pipelines.
If you installed it — respond
morty-package 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.
Did it already run?
If morty-package 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.
How O3 protects you
O3 blocks morty-package 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 morty-package-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
