Hook was named CEO of Neustar in October 2010. As President & CEO, Hook led the transformation of Neustar from telecom infrastructure to global leadership in information services. This resulted in the company being acquired at a 45% premium and going private. Prior to serving as CEO, Hook spent two years as the company's President & Chief Operating Officer, strengthening its market position and building partnerships with content and media industries. In January 2010, The Washington Post reported that under Hook's leadership, Neustar was chosen by a consortium of Hollywood studios and technology executives to manage a system whereby consumers could access movies and other video entertainment from multiple digital devices. In June 2011, Hook was the 2nd highest paid female CEO in the Washington, DC region. From 2006 to 2007, Hook served as CEO of Sunrocket, a privately held VoIP company. From 2000 to 2004, Hook held several senior leadership positions at AOL, including president of AOL Broadband, Premium & Developer Services. At the time of her appointment, The New York Times reported that Hook's "self-deprecating sense of humor masks an ability to solve complex business problems." Before working at AOL, Hook was a partner at Brera Capital Partners LLC, a private equity firm focused on investing in media and telecommunications. From 1989 to 1995, she worked at Time Warner, rising to Executive Vice President and Chief Operating Officer of Time Warner Telecommunications.

From 1987 to 1989, Hook served as senior legal adviser to the chairman of the Federal Communications Commission. She later said of this experience: "Being at the FCC in the Reagan administration was pure adrenaline. We were highly deregulatory and changed a number of policies."
