Chipotle Serves Up Chips, Guac & HR Email

The restaurant chain Chipotle Mexican Grill seems pretty good at churning out huge numbers of huge burritos, but the company may need to revisit some basic corporate cybersecurity concepts. For starters, Chipotle’s human resources department has been replying to new job applicants using the domain “” — a Web site name that the company has never owned or controlled.

The welcome message that one receives upon successfully submitting an application for a job at Chipotle discourages users from replying to the message. But Kohlman said a brief look at the incoming email associated with that domain revealed a steady stream of wayward emails to — mainly from job seekers and people seeking password assistance to the Chipotle HR portal.
