fluxhttpPyPI
Malicious code in fluxhttp (PyPI) Remove it immediately and rotate any exposed credentials.
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for fluxhttp (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging fluxhttp across your stack and pipelines.
If you installed it — respond
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.
Did it already run?
If fluxhttp 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 fluxhttp 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.

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.
