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.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for jupphelp (version 0.1.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging jupphelp across your stack and pipelines.

  2. If you installed it — respond

    jupphelp 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.

  3. Did it already run?

    If jupphelp was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks jupphelp before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. jupphelp on PyPI has been identified as a malicious package (version 0.1.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
