MEMORANDUM

Allegations of Hacking Election Are Baseless

A New York Times report on Monday alluding to "overwhelming circumstantial evidence" leading the CIA to believe that Russian President Vladimir Putin "deployed computer hackers with the goal of tipping the election to Donald J. Trump" is, sadly, evidence-free. This is no surprise, because harder evidence of a technical nature points to an inside leak, not hacking � by Russians or anyone else.

We have gone through the various claims about hacking. For us, it is child's play to dismiss them. The email disclosures in question are the result of a leak, not a hack. Here's the difference between leaking and hacking:

Leak: When someone physically takes data out of an organization and gives it to some other person or organization, as Edward Snowden and Chelsea Manning did.

Hack: When someone in a remote location electronically penetrates operating systems, firewalls or any other cyber-protection system and then extracts data.

All signs point to leaking, not hacking. If hacking were involved, the National Security Agency would know it � and know both sender and recipient.

They make some good points. The NSA would have real, exact evidence if this was a hack.
