Outdoor digital billboards, which had begun showing several advertisers on one board, were the subject of a DEF CON 16 talk titled "Hijacking the Outdoor Digital Billboard Network," which argued they were attractive targets to take apart and tinker with. Billboard Insider's write-up of the talk lists weaknesses including unencrypted network links open to packet sniffing and war dialing, and global or default usernames and passwords. A conference listing dates the talk to 2008, while one secondary source dates it to 2013, so the 2008 listing is the one used here.
