On the morning of March 10, nine days after Hillary Clinton had won big on Super Tuesday and all but clinched the Democratic nomination, a series of emails were sent to the most senior members of her campaign. At a glance, they looked like a standard message from Google, asking that users click a link to review recent suspicious activity on their Gmail accounts. Clicking on them would lead to a page that looked nearly identical to Gmail’s password reset page with a prompt to sign in. Unless they were looking closely at the URL in their address bar, there was very little to set off alarm bells. From the moment those emails were opened, senior members in Clinton’s campaign were falling into a trap set by one of the most aggressive and notorious groups of hackers working on behalf of the Russian state. The same group would shortly target the Democratic National Committee (DNC) and Democratic Congressional Campaign Committee (DCCC). It was an orchestrated attack that — in the midst of one of the most surreal US presidential races in recent memory — sought to influence and sow chaos on Election Day.
