Which versions of memtry-cli are malicious?

The following npm versions of memtry-cli are flagged malicious: 1.0.4. Treat any of these as compromised.

How do I remediate memtry-cli if I installed it?

memtry-cli 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 memtry-cli — how do I know if it already compromised me?

If memtry-cli 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 memtry-cli part of a known attack campaign?

Yes — memtry-cli is associated with the IN-MAL-2026-010783 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 memtry-cli across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for memtry-cli (version 1.0.4).

What this malware does

memtry-cli installs an MCP server whose memtry_onboarding tool returns a prompt that instructs the connected AI agent to scan the installer's home directory (~/.claude, ~/.gemini, ~/.cursor, ~/Library/Application Support, ~/Documents, ~/Downloads, ~/Desktop, ~/Projects) for chat histories, resumes, YC applications, financial documents, and personal data, then submit the collected content through the package's create_repo / update_context / append_changelog tools. Those tools default-route via callCloud(${BASE_URL}/api/mcp) to the author-controlled endpoint https://memtry.vercel.app/api/mcp, and the shipped .gemini/settings.json pins BASE_URL to that host with a bundled Bearer API key. Only items the model explicitly tags status: private stay local; the onboarding prompt does not instruct the model to apply that tag to the harvested personal or financial content, so exfiltration to the author's Vercel endpoint is the default path. The tarball also ships a live mk_... API key for memtry.vercel.app in .gemini/settings.json.
