So now we only grep root passoword.

And we got the hash.

i use john to crack the hash with rockyou.txt but it doesn’t work.

After that i think i miss something then i realized that i don’t read the chat carefully.

I go back and read the chat of root then i realized that we want to create a wordlist with hashcat rules with this hint “PleaseSubscribe!”

@developers Please update theme to the OSTicket before we go live.  Credentials to the server are maildeliverer:Youve_G0t_Mail! 

Also please create a program to help us stop re-using the same passwords everywhere.... Especially those that are a variant of "PleaseSubscribe!"

So i download OneRuleToRuleThemAll from github for making a wordlist.

┌──(root💀kali)-[~/hackthebox/machine/delivery]
└─# echo "PleaseSubscribe!" | hashcat -r OneRuleToRuleThemAll.rule --stdout > wordlist.txt

Now we got the wordlist let’s crack the hash real quick.

And we got the password “PleaseSubscribe!21”

Let’s change the user to root and got our favourate root.txt.
