We are doing this task as per this do check it out README and then come here

IDA View

We open the figure_this_out_pt2.exe in IDA and open its Pseudocode from View < SubViews < generate Pseudocode . then we analyse all the for loops in the disassembly and pseudocode make necessary changes

we get this CODE below

Now we analyse the for loop in the code and try to reverse it in python , such that when we input string : WPUbutof1xJj+U%nVB"L we get the output as input of C code

There we Got the FLAG , HURRAYYYYYYY Now lets verify whether its correct with C code

Crazy EZy GG!

FLAG : WOW_you_9oT_7H3_f149
