Hello guys it’s 0UR4N05 again , today i’ll solve a reverse engineering challenge

challenge description : Help crow to drink the water…..(something like that)

The solution of this challenge is the same to Vault and other challenges i’ll just do it .

So our executable need a password too , i’ll run strings to extract all strings in the executable

not too much , so i’ll run ltrace to extract strings while the program is running

again we have a strcmp function who compare our password with the original password

so we got our flag using ltrace .

Thanks for reading , 0UR4N05
