Which versions of jupsolhelp are malicious?

The following PyPI versions of jupsolhelp are flagged malicious: 0.1.0, 0.1.1, 0.1.2, 0.1.3. Treat any of these as compromised.

How do I remediate jupsolhelp if I installed it?

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

If jupsolhelp 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 jupsolhelp part of a known attack campaign?

Yes — jupsolhelp 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.

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.
