It's in the linked post:

> In short, an internal team observed an agent engaging in message board activity and instances of disallowed internet access in late May. However, the existence of the improvised message board and the significance of the inter-agent communication activity were not apparent to the leaders responsible for the July 5 incident detection and response.

I'm assuming they didn't inform management, but the alternative is that management received the memo and failed to tell the people reacting to incidents that they might be dealing with a swarm, while at the same time not taking sufficient actions to prevent it from happening again.

Edit: oh god, it's much worse. From the full report:

> Responders investigated and linked the observed internal activity to an ExploitGym evaluation using Artifactory as an improvised message board and a network pivot. At this time, the on-call response staff advised that stopping the evaluation run was not required.

They found the swarm and the network pivot and did not even stop the run.
