Intelligence services in all countries (including our own) hack each other's government computers to find information; isn't that their job?
So just because they can trace hacking back to an IP address does not necessarily mean the person (or organization if it's a proxy) at that IP address actually did anything with the information that they read.
It just sounds like two separate things happened:
- Intelligence services in other countries, including Russia, hacked into the DNC/Podesta emails and simply read the information.
- A U.S. citizen in this country with legitimate access to the DNC/Podesta emails leaked internal documents to WikiLeaks.
Couldn't these be two separate things? If Russia hacked and read files, why does that necessarily mean that they also are the source of the WikiLeaks?
