Now while being logged in as the user bandit10, you need to find the password of user bandit11 in order to complete this level.

If you haven’t completed the previous level, do check out the write-up for Level 9 to Level 10, which is present here.

Follow these steps to proceed:

  • Password for this level is stored in a file called data.txt which has been base64 encoded
  • We already have a built-in tool called base64 that does this encoding and decoding for us
  • Use the following bash one liner for this:
base64 data.txt --decode
  • This will give you the following output:
The password is <password>

Password obtained at the time of writing this write-up: dtR173fZKb0RRsDFSGsg2RWnpNVj3qRr

Note

Passwords on each of the levels are known to change regularly after a specific interval of time. So instead of skimming through the write-up, it is recommended to solve the challenge by hand.
