Which versions of flophttp are malicious?

The following PyPI versions of flophttp are flagged malicious: 2.3.5. Treat any of these as compromised.

How do I remediate flophttp if I installed it?

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

If flophttp 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 flophttp part of a known attack campaign?

Yes — flophttp is associated with the RLMA-2024-08282, 2024-08-invokehttp, RLUA-2026-00330 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 flophttp across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for flophttp (version 2.3.5).

What this malware does

In the invokehttp, the init.py contains obfuscated code attempting to download and run one of two executables. They are identified as malicious by VT and the tracks of Telegram URLs suggests attempting data exfiltration. The package itself looks like a copy of requests. In flophttp, using exactly the same obfuscation method, the infostealer is directly embeded into package code and exfiltrates data to a telegram channel.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
