DNC says suspected hack attempt turned out to be a security test

What the Democratic National Committee this week thought was an attempted hack of its valuable voter file turned out to be a security test organized by a state party, unbeknown to the national organization.

The committee on Tuesday alerted the FBI to a fake online portal it thought had been set up as an elaborate attempt to trick DNC staff into giving up their log-in credentials — through a hacking technique known as “phishing” — as a way to gain access to the party’s VoteBuilder database.
