all we have to do, after a bit inspection of the program flow inside of IDA, is to find x, where x is the solution to this thing:

x XOR b10101010(b10) = 1234567890(b10)

and x is read in hex format.

thus our x is 1234567890(b10) XOR 10101010(b10) = 490c23c0(b16)

inputting this gets us the flag!

./vuln                                       
Enter a hexadecimal number: 490c23c0
Good job! Go get your flag!
