What does the gemini-analyzer malware do?

The package is a RAT performing full exfiltration and executing remote commands through a custom RPC protocol over WebSockets, and eventually establishing a reverse shell. Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-05-gemini-analyzer Reasons (based on the campaign): - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine. - exfiltration-ssh-keys - files-exfiltration - exfiltration-credentials - rat - The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.

Which versions of gemini-analyzer are malicious?

The following PyPI versions of gemini-analyzer are flagged malicious: 0.1.0, 1.0.8, 1.0.9. Treat any of these as compromised.

How do I remediate gemini-analyzer if I installed it?

gemini-analyzer 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 gemini-analyzer — how do I know if it already compromised me?

If gemini-analyzer 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 gemini-analyzer part of a known attack campaign?

Yes — gemini-analyzer is associated with the 2026-05-gemini-analyzer campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
