Mission 0x24

🔎 Solution

After logging in via SSH as isabel, the next objective is to recover the password for the user freya.

isabel@venus:~$ cat mission.txt 
################
# MISSION 0x24 #
################

## EN ##
The password of the user freya is the only string that is not repeated in different.txt 

The file different.txt contains multiple entries, and only one of them is unique. The easiest way to extract it is by using the uniq -u command:

isabel@venus:~$ uniq -u different.txt 
EEDyYFDwYsmYawj

The output reveals the password for freya. With this credential, the next SSH login is performed:

ssh freya@venus.hackmyvm.eu -p 5000

Inside the new session, reading the final file provides the next flag:

freya@venus:~$ cat flagz.txt 
8===m1rRSv2pdm3sBGmgidul===D~~
