Before using the wireless transfer function, the user must setup a "profile" on the host PC. This profile must then be uploaded to the camera before it can transfer pictures wirelessly. To do this, the user must plug their camera into the host PC via a USB cable and run the "Wireless Camera Setup Utility." This program connects to the camera, and starts a setup process that will define the wireless settings the camera will need to know to connect to the PC. Items such as a designated printer, SSID of the wireless network, DHCP/static IP, and the shared key (WEP or WPA) are all specified under this "Profile." All this is necessary because there is no direct interface to these settings on the camera. We initially thought these packets included some kind of authorization mechanism that would keep out attackers (e.g. hash of picture, secret key, etc.), but as we learned, the only protection was based solely on the MAC address of the "camera," Niet echt dus. Je zal toch eerst de WEP/WPA key goed moeten hebben.
