Which versions of http-request-toolkit are malicious?

The following PyPI versions of http-request-toolkit are flagged malicious: 2.28.3, 2.28.4, 2.28.5. Treat any of these as compromised.

How do I remediate http-request-toolkit if I installed it?

http-request-toolkit 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 http-request-toolkit — how do I know if it already compromised me?

If http-request-toolkit 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 http-request-toolkit part of a known attack campaign?

Yes — http-request-toolkit is associated with the 2026-02-requests-toolkit, RLMA-2026-00396 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 http-request-toolkit across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for http-request-toolkit (3 malicious versions).
