Nice try, Wapo.
Did they? It appears in news reports that that released data was faked.
GUCCIFER 2.0 HACKED CLINTON FOUNDATION
Having looked over Guccifer's massive archive, I must say, those files don't look like they came from the Clinton Foundation. They look like more DCCC material.
If you want to see for yourself, the download link is https://uploadfiles.io/ebd, and the 7z password is '(GuCCif3r_2.0)' (the parens are part of the password). The file is 860,107,023 bytes long. On a Mac command line, you can unpack it with:
7za x "-p(GuCCif3r_2.0)" ebd-cf.7z
On other platforms, just google 7z.
The 7za output will be a directory named 80fccea01a230134041c0ee73fee24a3, below which will be the files.
Hmm. It just occurred to me to google that directory name, and I landed here. So, if you're bandwidth-challenged, ignore the above and just go there.
