Which versions of juphelp are malicious?

The following PyPI versions of juphelp are flagged malicious: 0.1.0. Treat any of these as compromised.

How do I remediate juphelp if I installed it?

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

If juphelp 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 juphelp part of a known attack campaign?

Yes — juphelp is associated with the 2024-08-sleipnirbrowser-web3 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 juphelp across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for juphelp (version 0.1.0).

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.
