It is ridiculous to think that the Russkies planed and executed these hacks as a deliberate operation with a clear objective to derail the election or whatever it might me.
Some guys routinely spreading primitive phishing spam got lucky and got a password or two and gained the access to emails. Just this. No super spy hacking operations. It does not even work that way - chance is the main factor.
How the emails turned up on Wikileaks is another questions, but, again, they have been published because they have been already hacked by some primitive phishing gang, not super-intelligent top-tier mega-hackers paid by the evil KGB.
The whole idea of deliberate planed KGB operation is an utter nonsense. It were kids with PHP crap. One should look for the brokers. They could have been among the 35 kicked out guys.
