Which versions of netmanagement are malicious?

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

How do I remediate netmanagement if I installed it?

netmanagement 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 netmanagement — how do I know if it already compromised me?

If netmanagement was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is netmanagement part of a known attack campaign?

Yes — netmanagement is associated with the 2025-08-netmanagement 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 netmanagement across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for netmanagement (2 malicious versions).

netmanagement is a confirmed malicious PyPI package (MAL-2025-191802) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.0, 0.1.1). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

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

pip uninstall netmanagement

What this malware does

The package appears to be a PoC of overwriting "requests" package files. The new "requests/init.py" takes over common requests features and uses the implementation that a) logs every request to a file (but no external exfiltration, this may also be expected in some situations); b) after every 5 requests, opens the calculator app. The second shows clearly that the intention is to present a security risk, not create a real package.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Detect & block this

O3 blocks netmanagement-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
