Web Enumeration ⤵️
Lets see the directory or files bruteforcing files —>
Lets got to this file →
Lets decode this base64 encoded in readable form →
Now lets see this data.png file and decode it further since it is qrcode so →
Now I got a string → Password : topshellv →
But on further enumeration I find this password as a rabbit hole so lets dig in further through directory or files bruteforcing with rockyou.txt file →
Now I got a directory named as /bulma/ →
Now I got a audio file so lets decode it with morse code decoder →
https://morsecode.world/international/decoder/audio-decoder-adaptive.html
From decoder I got the credentials →

Now lets the file permissions →
Since this file can be modifed as trunks too so lets go and add a new user with root privileges →
First we need to choose a password, salt it and hash the result. openssl to the rescue.
Flags:
- -
1what hashing algorithm to use. In our use case it doesnt matter, therefore we use MD5 which should be avoided in real world PT as it is not secure. - -
salt saltstring to use as salt. I choose the string salt passwordclear text password we would like to use.

2
$ openssl passwd -1 -salt salt password
$1$salt$qJH7.N4xYta3aEG/dfqo/0
we need to add some data in order for it to be aligned with the /etc/passwd format. This is the final result:
1
shiv:$1$salt$qJH7.N4xYta3aEG/dfqo/0:0:0::/root:/bin/bash
I named the user shiv. now lets write into the /etc/passwd file with nano →
