This is what Guccifer 2.0, who has denied being affiliated with the Russian government claiming that like the original Guccifer he is from Romania, posted moments ago on his website:

So, this is the moment. I hacked the Clinton Foundation server and downloaded hundreds of thousands of docs and donors' databases.

Hillary Clinton and her staff don't even bother about the information security. It was just a matter of time to gain access to the Clinton Foundation server.

The unknown hacker has allegedly exposed 1,000 of Hillary donors (a small list of master donors can be found here)...

...corporate donations made to various House representatives....

As Guccifer notes," It looks like big banks and corporations agreed to donate to the Democrats a certain percentage of the allocated TARP funds."
