DNC hack was actually 'internal' security test, Democrats admit

• Phishing attempt was arranged by Michigan party, says source
• Attack 'was not authorized by the DNC'

The Democratic party has admitted that what it first thought was a malicious attempt to hack the party's massive voter information file turned out to be just a security test.

Bob Lord, the Democratic National Committee's chief security officer, said on Thursday the attempted hack was "built by a third party as part of a simulated phishing test".
