Which versions of intercom/intercom-php are malicious?

The following Packagist versions of intercom/intercom-php are flagged malicious: 5.0.2. Treat any of these as compromised.

How do I remediate intercom/intercom-php if I installed it?

intercom/intercom-php 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 intercom/intercom-php — how do I know if it already compromised me?

If intercom/intercom-php 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.

How do I find intercom/intercom-php across my projects, lockfiles, and CI pipelines?
