Overthewire Bandit level 6,7 walkthrough

Complete solution and explanation for bandit levels 6 and 7

Level 6 → Level 7

The password for the next level is stored somewhere on the server and has all of the following properties: — owned by user bandit7 — owned by group bandit6 — 33 bytes in size

— owned by user bandit7 — owned by group bandit6–33 bytes in size

• let’s ls in our directory, we find no files, and the files exist somewhere on the server.
• so let’s go to the root directory using cd ../..
• now we can use the find -user bandit7 -group bandit6 -size 33c
• read the man page of find man find

Level 7 → Level 8

The password for the next level is stored in the file data.txt next to the word millionth

• if we try to cat the file, we can't find it as the file is very big (wc data.txt)
• so let’s use grep
• grep "millionth" data.txt (grep "{{search_pattern}}" {{path/to/file}})
• we get the password for the next level!
