How do I remediate mt8320mzji if I installed it?

Remove mt8320mzji from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed mt8320mzji — how do I know if it already compromised me?
