David, we have a critical alert on node four! Several virtual machines are reporting encrypted file extensions and heavy CPU spikes.
That looks like an active ransomware payload. We must immediately isolate the subnet from the main enterprise gateway.
I have just disconnected the core switch. The compromised virtual machines are now strictly quarantined.
Excellent reflex. Let's verify the integrity of our air-gapped immutable backups before initiating the full system recovery.
The offline backup repository is intact and verified. We can safely format the infected volume and restore clean snapshots.
Perfect. Once the restore is complete, we will patch the vulnerability and write the post-incident report.
