Which versions of jupiter-helper are malicious?

The following PyPI versions of jupiter-helper are flagged malicious: 0.1. Treat any of these as compromised.

How do I remediate jupiter-helper if I installed it?

jupiter-helper 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 jupiter-helper — how do I know if it already compromised me?

If jupiter-helper 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 jupiter-helper part of a known attack campaign?

Yes — jupiter-helper is associated with the RLMA-2024-08429, 2024-08-sleipnirbrowser-web3, RLUA-2026-00442 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 jupiter-helper across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for jupiter-helper (version 0.1).

What this malware does

Once run, downloads and install from sleipnirbrowser[.]org a suspicious executable pretending to be a webbrowser. This website appears to be a scam using some kind of crypto tokens, and trying to impersonate a legitimate Slepnir web browser (https://en.wikipedia.org/wiki/Sleipnir_(web_browser)).

Later versions switched to install a software identified as LUMMA infostealer (e.g. https://tria.ge/240817-whze2aydkc), hidden in different executables

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