Before this, mostly what they were doing was small time. DOSing a website, or leaking some emails is annoying, this could potentially get people killed.
This is max level from what I'm reading so far (others' reports, I'm not touching that torrent). Homeland security info, info on ongoing investigations, etc. etc.
This might actually make lulz more dangerous. They have nothing to lose now. Before this, I'm sure in the back of the heads of whoever was doing whatever, was the thought of getting caught, and that they might go to jail for a couple of years. It doesn't matter anymore, because nothing that they can do now can make things worse for them. If [when] they get caught, they're going to prison for the rest of their lives or worse.
Basically: consequences will never be the same.
