Level 5 → 6

Level Goal

The password for the next level is stored in a file somewhere under the inhere directory and has all of the following properties:

• human-readable

• 1033 bytes in size

• not executable

Write-Up

1. Find the file matching the specific criteria:

find inhere -type f -readable -size 1033c ! -executable

• find inhere: Start searching in the 'inhere' directory

• -type f: Look for regular files

• -readable: Find human-readable files

• -size 1033c: Look for files exactly 1033 bytes in size

• ! -executable: Exclude executable files

This command reveals .file2 as the only file meeting all requirements.

1. Display the content of the identified file:

cat $(find inhere -type f -readable -size 1033c ! -executable)

• cat: Command to display the content of a file

• $(): Command substitution. It allows the output of a command to be used as an argument for another command

Or

cat inhere/maybehere07/.file2

This outputs the password: HWasnPhtq9AVKe0dmk45nxy20cvUa6EG

1. Access the next level:

ssh [e-mail] -p 2220

Enter the password when prompted.

Lessons Learned

• The find command can search based on multiple criteria simultaneously

• File attributes like size and permissions can be used as search parameters

• Command substitution ($()) allows for combining commands efficiently

• Hidden files (starting with .) can contain important information
