The National Counterterrorism Center (NCTC) is warning law enforcement and first responders that urban exploration, an activity that involves trying to gain access to restricted or abandoned man-made structures, can provide useful information for terrorists conducting surveillance of a potential target. Also known as “building hacking”, urban exploration has been around in its modern form for decades, tracing some its more recent history to post-war exploration of the Parisian catacombs and members of MIT’s Tech Model Railroad Club Signals and Power Subcommittee, who organized explorations of steam tunnels and rooftops around campus in the late 1950s.
(U//FOUO) National Counterterrorism Center: Urban Exploration Offers Insight on Infrastructure Vulnerabilities
Urban Explorers (UE)—hobbyists who seek illicit access to transportation and industrial facilities in urban areas—frequently post photographs, video footage, and diagrams on line that could be used by terrorists to remotely identify and surveil potential targets. Advanced navigation and mapping technologies, including three dimensional modeling and geo-tagging, could aid terrorists in pinpointing locations in dense urban environments. Any suspicious UE activity should be reported to the nearest State and Major Area Fusion Center and to the local FBI Joint Terrorism Task Force.
