Take a look at the following Twitter: https://twitter.com/finestsquad

At least one of them, a 17-year-old from Canada, has already been arrested.

The personal information of most of the rest of the group has already been publicly spread by "Finest Squad" and sent to law enforcement (though I imagine law enforcement probably already knows who most of them are, especially if other random Internet users can find their names and addresses so easily).

At that point it's just a matter of monitoring and building up a strong enough case.

What's there to back up the legitimacy of the information released by these guys?

It just looks like they're tweeting out random IPs from zeustracker.

If you're familiar with some of the script kiddie communities these people hang out in, it's not that hard to check their work.

It's quite possible they got a few wrong; I have not independently confirmed the information and I'm not sure anyone else has. One can clearly tell what sort of individuals the perpetrators are, though, and US law enforcement typically does not have a lot of trouble identifying and rounding up egotistical script kiddies. Look at LulzSec and all the copycats.

Feel free to put my comment on a calendar: I'd bet a fair bit of money that 75% or more of the group will be arrested before Christmas of 2015.

All "finestsquad" seems to have done is doxed various people the lizardsquad twitter has followed over time, I doubt they're stupid enough to follow themselves.

That is not what they have done at all.

These aliases and information are present on channels far away from Twitter.
