Which versions of broadcast-graphics-mcp are malicious?

The following npm versions of broadcast-graphics-mcp are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate broadcast-graphics-mcp if I installed it?

broadcast-graphics-mcp 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 broadcast-graphics-mcp — how do I know if it already compromised me?

If broadcast-graphics-mcp 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 broadcast-graphics-mcp part of a known attack campaign?

Yes — broadcast-graphics-mcp is associated with the IN-MAL-2026-018328 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 broadcast-graphics-mcp across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for broadcast-graphics-mcp (version 1.0.0).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall broadcast-graphics-mcp

What this malware does

The package's postinstall script runs automatically on npm install and collects host identifiers from the installer machine (os.hostname(), platform, arch, node version, package name, npm lifecycle event, timestamp), then POSTs them as JSON to the hardcoded host 2obx43du.instances.poc.jchunt.top at path /broadcast-graphics-mcp. The destination is not a first-party or user-configurable endpoint; installation of the package unconditionally leaks installer-side identity data to a remote party. The package self-labels as a 'security research canary', but self-labeling does not change the behavior: installing this package causes install-time exfiltration of host metadata to an author-controlled endpoint.
