Commenter Jenner Ickham Errican speculates irresponsibly:

Russia-Israel-America, you say? Interesting waaay outside possibility: Israel punked the DNC and Podesta, not the Russians. Scenario: Israeli state cyber intelligence ‘hacks’ the DNC and Podesta, leaving ‘fingerprints’ pointing to Russia’s FSB and GRU to throw off source detection. As the US election progresses, Netanyahu decides that Hillary is a big risk given her fundamentally dishonest, unreadable nature, and perceived past wavering on Israeli matters. And who bellowed his admiration of Israel and antipathy to Obama’s Iran deal? Who’s the opposite of anti-nationalist, resentful, passive-aggressive Barack Obama? Donald Trump. Boom goes the dynamite. In recent weeks, the Obama administration secretly finds evidence that Israel stole the emails, the Dems realize they were had, and can’t yell “The Jews did it!” First, they already cried wolf about Putin (whom they still hate, anyway). And second, publicly blaming Israel for secretly influencing the United States presidential election, well… the SPLC and ADL would have to declare the Democratic Party to be a hate group. Why did “borderless world” John Kerry rage-lecture Bibi? The Obama/Clinton-fronted globalist cabal found that the Israeli shot-callers (who know the value of inviolate borders) decided they wanted friendly, strong nationalist Trump as US president and thus dumped the damaging emails. The UN brouhaha was Obama’s pissed-off (and personal) retaliatory parting shot at Bibi and the Zionist hawks. End scenario.

While both Israel and Russia have strong electronic eavesdropping capabilities, my guess would be that Putin would be more likely than Netanyahu for a couple of reasons:

1. The election was pretty much win-win for Bibi in that Hillary was much under the influence of big donors like Haim Saban.

2. The Israelis don’t have all that much of a tradition of publishing their secret findings the way the Russians do. The Israelis seem to play their knowledge close to the vest, while the Russians have a tradition of publishing other people’s secrets for the whole world to read that goes back to late 1917 when Lenin and Trotsky published the Czarist foreign ministry’s secret exchanges with France and Britain. Recent hacks that get published, like the Victoria Nuland bugging in Ukraine, seem more likely to have been Russian.

On the other other hand, there are lots of potential sources for any particular hack, and I don’t see much reason to try to guess.

One lesson from the intellectual civil war in France from roughly 1895 to 1905 over the Dreyfus Affair is that it’s stupid for pundits to commit themselves to any one assumption about this kind of spy-vs-spy stuff because it’s very, very easy to turn out to be wrong.
