Electromagnetic Field (EMF) is a camping festival for hackers, creative types, and generally the all-around curious in an English nature reserve. This year, every attendee was given a special festival badge which doubled as a fully functional, open source phone.
But hackers being hackers, someone at the festival deployed their own surveillance device, a homemade IMSI catcher, extracting sensitive information from attendees' badges and sending text messages en masse.
"There were spoofed texts being bombarded," one person who attended EMF last weekend said. Motherboard granted sources for this story anonymity to discuss potentially illegal activity more candidly.
