*
* 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
