Which versions of learning-pypi-demo-nisimi are malicious?

The following PyPI versions of learning-pypi-demo-nisimi are flagged malicious: 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.5. Treat any of these as compromised.

How do I remediate learning-pypi-demo-nisimi if I installed it?

learning-pypi-demo-nisimi 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 learning-pypi-demo-nisimi — how do I know if it already compromised me?

If learning-pypi-demo-nisimi 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 learning-pypi-demo-nisimi part of a known attack campaign?

Yes — learning-pypi-demo-nisimi is associated with the RLMA-2025-04786, 2025-08-learning-pypi-demo-nisimi, RLUA-2026-00467 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 learning-pypi-demo-nisimi 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 learning-pypi-demo-nisimi (6 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging learning-pypi-demo-nisimi across your stack and pipelines.

Detection & response playbook

Credential / info stealer

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for learning-pypi-demo-nisimi (6 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging learning-pypi-demo-nisimi across your stack and pipelines.
If you installed it — respond
learning-pypi-demo-nisimi 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 learning-pypi-demo-nisimi 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 learning-pypi-demo-nisimi 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.
