Which versions of fluxhttp are malicious?

The following PyPI versions of fluxhttp are flagged malicious: 1.0.1, 1.0.2, 1a1. Treat any of these as compromised.

How do I remediate fluxhttp if I installed it?

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

If fluxhttp 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 fluxhttp part of a known attack campaign?

Yes — fluxhttp is associated with the 2026-03-license-utils-kit 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 fluxhttp across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for fluxhttp (3 malicious versions).

What this malware does

Malicious clone of a legitimate package. When using it, the code attempts to download and execute remote code. In on of the incarnations, the malicious code was embeded in the strongly obfuscated file, which at least collected data from cryptowallets and password managers and exfiltrated them to a hardcoded remote location.

The downloaded next stage varies depending on the running platform. On Windows, it's extream obfuscated script. On Linux and MacOS they are binaries, named "systemd-resolved" and "com.apple.systemevents" with clear signs of stealing browsers and cryptocurrency data.

Detect & block this

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