So far I haven't seen any journalist go to the effect to document exactly what happened to Podesta on the day his passwords were leaked to 4chan.
Edit: I found this on slashdot from the time of the password leaks. https://mobile.slashdot.org/story/16/10/13/2025257/4chan-hac...
Edit 2: More proof that regular people gained access to his Gmail account. Seemingly whoever gained access to his twitter account did so via a password reset using his Gmail address. https://twitter.com/pwnallthethings/status/78662164964259840...
This for me is the ultimate card that the leaks weren't a grand conspiracy to elect Trump. Rather a security illiterate person got completely owned by trolls on the internet.
Edit 3: Further more, if the Russians were really behind the phishing to capture Podesta's passwords why would they leak on 4chan where they would end up losing their control of his accounts? A state actor would try to maintain access for as long as possible. A troll would rather see everything explode.
