I am curious to know what happened in 2012 that all these breaches occurred. I assume they are holding the data, and trying to squeeze what they can out of it all the way through. However this year there seems to have been a lot of massive breaches that year. does it all stem from one hack? 200m Yahoo accounts could lead to at least a few million LinkedIn accounts I would assume, maybe not as many as was actually compromised in the LinkedIn breach, but still. I just want to know if the same exploits were used in all of these instances. Or maybe they have just found backups for all these companies this year from 2012 and are using those. I don't even how that would happen.

If they found a yahoo employee credentials in the linkedin hack (or vice-versa) then they don't need a million accounts, just those credentials. "Hackers who used an employee’s password, re-used from the LinkedIn breach, to access Dropbox’s corporate network and steal the user credentials" - from a unnamed source quoted in a techcrunch article. So maybe they also managed to traverse from linkedin to Yahoo or Yahoo to linkedin through similar password re-use.
