Intel Vets Challenge ‘Russia Hack’ Evidence

Forensic studies of “Russian hacking” into Democratic National Committee computers last year reveal that on July 5, 2016, data was leaked (not hacked) by a person with physical access to DNC computer. After examining metadata from the “Guccifer 2.0” July 5, 2016 intrusion into the DNC server, independent cyber investigators have concluded that an insider copied DNC data onto an external storage device.
Key among the findings of the independent forensic investigations is the conclusion that the DNC data was copied onto a storage device at a speed that far exceeds an Internet capability for a remote hack. Of equal importance, the forensics show that the copying was performed on the East coast of the U.S. Thus far, mainstream media have ignored the findings of these independent studies [see here and here].
