I managed to solve this one too ＼(≧▽≦)／.
Task :
Task Files : Warmup.rar [download]
> After Downloading the attached file I (as usual) directly threw it into IDA and hit the decompile button (F5).
> By doing that and reading through code i first met this :
> Once executed, The binary takes a string that has 27 as a length.
> Then there is this long set of assignments :
> It is obviously something, but those are not ASCII values as they are all above 127.
> Taking a look at the final part of the code :
> As it seems everything is understandable, the "for" there is just a loop that cycles through the whole array of characters that was made before, the only weird thing is that ">>" operator.
> What that operator does is that if, For example, We take an integer “X” with an integer “Y” and write X>>Y, that is equivalent to dividing X by 2y.
> So it seems like the array is actually holding Ascii values but right shifted ( that's what this operator ">>" is called ), Using my quite decent programming skills I wrote this script which after running got me the flag like this :
