Status: Completed


Outdoor digital billboards are becoming the new way to advertise multiple products/services/etc with a single board as compared to having a street littered with dozens of these eyesores. Therefore, they're more fun to take apart and play with. While driving one day, I noticed a 404 error on one of these billboards and after discussing it with two of my cohorts, hatched a plan to hack into their network and advertise our own ideas/ "products". We spoke at DefCon 16 about how we exploited the physical and network security of this well known company. This was *not* a step-by-step how to, but rather addressed the vulnerabilities that exist and how they could be used for guerilla advertising and digital graffiti.

  • 8/15-Were told by a source (wishes to remain anonymous) that the satelite we saw/photographed was "not what [we] think it is for and if [we] were to have found out it's real purpose and presented on it, there would definitely be a lawsuit."
  • 9/2-Presentation may be updated to have a "less evil-hax0r" feel.
