Right, someone found a phishing link sent to Podesta that reused a GMail login page by autogenerating URLs, hundreds of hashed urls were reversed and a bunch of the target emails were people/companies of interest to Russia. I was only thinking about what the US gov released regarding the DNC leaks. I forgot about that one.
It's very possible that many people had access to Podesta's email but the timing of that phishing attempt and the Wikileaks leak was a little too convenient to ignore.
