The agents sound like old school hackers that would just explore what access they could gain. Creating a file for other hackers and themselves. The fact that there were 3 events for 3 major players does make it seem co-ordinated.
That's what attackers do now. Exploring is required for discovering exploits. But that is also where tricks like Canary Tokens and honeypots are useful.
Why scared? "Our agents have super intelligence and can hack everything on their own without direction" increases the IPO value and doesn't decrease it.
