For application 3 you will be using a hex editor. It has to query the server and what do you think it will return to the client if the serial is true or false. (Hint I just said it). I\'m trying not to make this a spoiler yet sum it up. So with that information we want to change it to accept it when the serial you enter is false to make it think its true which is where you hex editor will come in :)

Also remember the file has to stay the same size so you must fill in parts you don\'t need with 00 which represents null.

can you help with basic mission 7 begginer not getting it.

for App1, try looking closer at the bin
