Puts me in mind of this scathing report from CISA on how a state-sponsored group broke into Microsoft and then into the State Department and a bunch of other agencies. Reads like a heist movie.

What I found most incredible about the story is that it wasn't Microsoft who found the intrusion. It was some sysadmin at State who saw that some mail logs did not look right and investigated.
Ah yes, back when the US actually had cyber defence and experts capable of working in their respective fields.
Don't worry CISA and any other involved regulator were gutted by DOGE.
