Large technological systems can be vulnerable to manipulation, perhaps especially when they are centralized, monopolistic, and complacent. That was the situation in American telecommunications in the early 1960s when a generation of hackers developed techniques to manipulate the Bell telephone system to their advantage, a practice known as phone phreaking.  

In his dissertation research, Jacob Bruggeman, PhD candidate at the Johns Hopkins University, digs into the technology and politics of hackers, tracing their trajectory from anti-establishment actors on the fringes of technological systems, to positions of influence and control over the very same systems. In parallel to these developments in the hacker community, major organizations, both public and private, adopted new positions and policies designed to secure the system. 

In support of his research, Bruggeman received funding from the Center for the History of Business, Technology, and Society at the Hagley Museum and Library.
