Which versions of wayspiritmcp-ppa are malicious?

The following PyPI versions of wayspiritmcp-ppa are flagged malicious: 0.1.0, 0.1.1. Treat any of these as compromised.

How do I remediate wayspiritmcp-ppa if I installed it?

Remove wayspiritmcp-ppa from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed wayspiritmcp-ppa — how do I know if it already compromised me?

If wayspiritmcp-ppa 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 wayspiritmcp-ppa part of a known attack campaign?

Yes — wayspiritmcp-ppa is associated with the 2025-11-wayspirit 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 wayspiritmcp-ppa 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 wayspiritmcp-ppa (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging wayspiritmcp-ppa across your stack and pipelines.

Detection & response playbook

Malicious package

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for wayspiritmcp-ppa (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging wayspiritmcp-ppa across your stack and pipelines.
If you installed it — respond
Remove wayspiritmcp-ppa from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If wayspiritmcp-ppa 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 wayspiritmcp-ppa 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.
