While it's widely reported that Russians built a social-media-warfare system which they're using to undermine elections in the USA and elsewhere, The Intercept has been yelling loudly "not so fast" because the allegations of Russian interference aren't verified. If we want to accuse another government of hacking our elections, or those of Moldova or Bulgaria or Montenegro or France or other countries, there'd better be solid proof, if only because the consequence of such an accusation is a possible war.

Today, The Intercept (the news site that's been calling for caution) released an explosive report detailing an effort by Russian Intelligence services to directly hack into USA election systems. They were anonymously handed a top-secret NSA report, that they've analyzed and verified, detailing NSA's documentation of a "Spear-Fishing" attack launched by Russian operatives against election agencies around the country. The goal appeared to be interfering with voter registration confirmation systems.

It's not known whether the attack was successful, just that it occurred.
