this starts with knowing the port 502 is runing mbap fro the output of the port scannig of padwan domain. after a bit of recearch i foud out that mbap is like the bus inside the pc and it has registers. i tried diffrent commands to read the registers starting from the holding registers witch returned numbers. these numbers didnt make any sense in the start and i had to search a bit in the internet on what these numbers could mean, and after giving up that day, the next day i started directly searching in internet and ai and i found out that the numbers could be in ascii. so i googled an ascii table and i started converting the numbers into letters starting from the 1 register untill register 41 otherwise the rest didnt have any numbers , only zeros. i then checked the what i am getting and sinse it startied with hack then i new i was going right. the problem here the process of translating was too slow and it seems i messed up and forgot some numbers while translating and got a flag that doesnt work where there was numbers in words witch i spendt quite sometime trying to fill up the numbers with letter to make the flag have a proper meaning and that wasted my time, later on i found a python script in the internet that actually connectes to mbap aand then reads the holding registers and translate the numbers to chars and returns the eright answer. stright away. after running the script i got the flag XD
