Goal: Find the password and log into level 10. The password is in the data.txt file and is the only human readable code preceded by multiple ’=’
If we try to cat data.txt we will see that the the file is mainly non-human readable text. What we can do is feed this all into grep to search through it for us. We will use the the -a flag to process a binary file as if it were text otherwise it will try to interpret the binary.
bandit9@bandit:~$ cat data.txt | grep -a '==='
