PORT 80 (HTTP)
It looks like we need to add delivery.htb to /etc/hosts
We can also see that Helpdesk would lead us to a sub domain help.delivery.htb so we should add this to /etc/hosts
PORT 8065 (HTTP)
On adding the domain in /etc/hosts
help.delievery.htb
On selecting Open a new ticket
After creating a ticket we will get a token number and a mail which we will use to register on Mattermost which is on delivery.htb
On logging in with the registered email
delievery.htb
Visit this domain and register with the token_number@delivery.htb which will then send you the email verification link
We will get these credentials maildeliverer:Youve_G0t_Mail!
Also this message
Also please create a program to help us stop re-using the same passwords everywhere.... Especially those that are a variant of "PleaseSubscribe!"
PleaseSubscribe! may not be in RockYou but if any hacker manages to get our hashes, they can use hashcat rules to easily crack all variations of common words or phrases.
Login here with the credentials
But there was not nothing on ostickets so I tried these credentials by logging in with ssh
Going into /opt directory I found a folder named mattermost.
Again we see an interesting folder named config
And we can see credentials for the mysql database
Mysql is running on port 3306 which is the defualt one so let's try logging in with the credentials we found
At the end we see a table named Users
We will get the information for root user including the password hash
Visiting Name That Hash website we can see that this is bcrypt hash
Save the hash in a text file
Now remeber the message that we saw from Mattermost chat that we need to use hashcat rules for the variation of PleaseSubscribe!
For creating hashcat rules I visited this page
https://hackingvision.com/2020/03/27/hashcat-rule-based-attack/
Here it talks about Hob0Rules
So let's run hashcat with the bcrypt hash against the password and the rule
It took a lot of time to crack the hash as I don't have a good GPU
