The FBI/DHS and Obama administration are touting evidence that the Russians were behind the DNC email leak.
But, a professional anti-hacking group looking at the evidence provided is far from convinced: Wordfence: US Govt Data Shows Russia Used Outdated Ukrainian PHP Malware
In short, the professionals are of the opinion that the odds that the Russians were using outdated Ukrainian designed malware from sites outside of Russia and mainly in the US is rather remote and this is pretty darn weak tea for proof that the Russians hacked the DNC and were responsible for the leak of the emails.
I realize the Democrats are pissed that their and John Posdesta's security awareness in particular was so piss-poor that their email showing their rather bad acts was leaked to the world and hurt them badly at election time. I understand that they need to deflect from their failings and the content of the emails with this bit of kabuki theater to make it the big bad Russians responsible for the leak rather than their own stupidity, but come up with better evidence than this before you cause a diplomatic incident, ok?
