This is probably just a probe by someone so bored that they are simply looking for someone to flash (as in flash.c). This attack is simply to send characters to the screen to mess up the user’s window. Note that two address families are shown in your slide; this was a pretty large scan. Doom is an older game that uses a default port of 666.Is this an asymmetric attack or a symmetric attack? __________________If this is a response, can you describe the stimulus packet?
