Which versions of requests-ml-min are malicious?

The following PyPI versions of requests-ml-min are flagged malicious: 3.45. Treat any of these as compromised.

How do I remediate requests-ml-min if I installed it?

requests-ml-min 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 requests-ml-min — how do I know if it already compromised me?

If requests-ml-min 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 requests-ml-min part of a known attack campaign?

Yes — requests-ml-min is associated with the 2026-02-urllib-slim 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 requests-ml-min 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 requests-ml-min (version 3.45). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging requests-ml-min across your stack and pipelines.

MAL-2026-1240

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall requests-ml-min

What this malware does

During installation, the package starts obfuscated code that downloads and runs remote executables in specific environments. In some packages in the campaign, the code only attempts to exfiltrate some basic information using DNS requests and then likely cover tracks by installing a similarly named package from private repository

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 requests-ml-min (version 3.45). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging requests-ml-min across your stack and pipelines.
If you installed it — respond
requests-ml-min 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 requests-ml-min 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 requests-ml-min 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.
