I'm predicting it is an AI or the teens were paid to act as the hackers. Look at what this hacking group has done and how they are doing it.
1. They are funded. There is real money behind these 'hacks'.
2. One of the key drivers to their success is they are PAYING people to access networks NOT give data. It's a thin line but I bet there are laws there that make the penalties orders of magnitude in difference to the individuals.
3. They are well organized... now maybe organizing raids has taught these kids how to do this right or it's just a thing. But Kids coming into and dealing with that kind of money and or noteriety are rare. And even more rare for them now to flash it somehow.
I suspect as I said before that these kids are being directed and paid to execute these actions for a separate 3rd party.
