Picoctf Cyborg Secrets -80 Write up

You found a password protected binary on the cyborg relating to its defensive security systems. Find the password and get the shutdown code! You can find it on the shell server at /home/cyborgsecrets/cyborg-defense or you can download it here.

This problem can be done in different ways. I used a method involving a command called 'strings' which basically shows you a list of all strings that have been executed along with the file.

Using the shell, you can cd to /home/cyborgsecrets/ and run the command 'strings cyborg_defense'.

After some trial and errors, I found out that the password required is 2manyHacks_Debug_Admin_Test.

Then you can execute the file with this password to login as admin and get your flag

Password: 2manyHacks_Debug_Admin_Test Flag:403-shutdown-for-what
