Comment Re:No support for dynamic address assignment?!? (Score 1) 287 287

DHCP client sends the DHCPRequest message, containing the MAC address of the client, to the limited IP broadcast address and to the MAC-level broadcast address. The DHCP Server/ Relay Agent receives this packet and replies with a reservation or forwards it as a directed IP packet to the configured DHCP server or servers.

Comment They have Ki's (Score 5, Informative) 99 99

Chances are they have the IMSI Ki keys. This is the info that is given to the carriers with each IMSI(SIM). That's all that is needed to dupe a SIM or decrypt coms. The vast majority(probably all) of these will use the default A3 /A8 encryption, so this will be a walk in the park (load IMSI+Ki into new card) to spin off duplicate SIMs for the next few years. Once you can dupe a SIM, you can then fool the VLR/HLR into redirecting calls/SMS or access Voicemail. No need to monitor the local airwaves.

Correct me if I'm wrong but the screen is transparent. Light from the environment passes through the display. AFAIK, there isn't such technology to accomplish this masking of environmental light (at the require frame rates). Put it this way, if there was, the projector manufactures would be using it now.
