> They’re also not saying how much actual message content they have because the 410GB of heap dumps makes for a bigger headline number.
That's very important to say. I went through one of these massive data dumps recently and it was literally all cached operating system package updates and routine logs. Nothing at all of interest.
It's easy to cut the size on a heap dump. When it's not done it seems sketchy. But it could be a 512GB dump and already pruned, so I could be wrong.
Most of the the heap dump will be filled with stuff like java.util.String!blahjava.util.ArrayList!
Though the heap dump would have messages in flight at the time. It's obviously not as useful if you are just trying to grab messages for a specific person.
Frankly the most useful part might be any in-memory secret keys, which could be useful for breaking deeper into the system.
