    TryHackMe Advent of Cyber 2 Day 1 Walkthrough


    The platform develops virtual classrooms that not only allow users to deploy training environments with the click of a button, but also reinforce learning by adding a question-answer approach. Its a comfortable experience to learn using pre-designed courses which include virtual machines (VM) hosted in the cloud.

    TryHackMe Advent of Cyber 2 Day 1 Walkthrough

    While using a question-answer model does make learning easier, TryHackMe allows users to create their own virtual classrooms to teach particular topics enabling them to become teachers. This not only provides other users with rich and varied content, but also helps creators reinforce their understanding of fundamental concepts.

    Advent of Cyber 2

    Get started with Cyber Security in 25 Days - Learn the basics by doing a new, beginner friendly security challenge every day leading up to Christmas.



    Task 6 [Day 1] Web Exploitation A Christmas Crisis

    "The Best Festival Company's brand new OpenVPN server has been hacked. This is a crisis!

    The attacker has damaged various aspects of the company infrastructure -- including using the Christmas Control Centre to shut off the assembly line!

    It's only 24 days until Christmas, and that line has to be operational or there won't be any presents! You have to hack your way  back into Santa's account (blast that hacker changing the password!) and getting the assembly line up and running again, or Christmas will be ruined!"



    The Web:

    The Internet is one of those things that everyone uses, but few people bother to learn about. As hackers, it is vital that we understand what exactly the web is, and how it works.

    When you open up your web browser and navigate to a website, it seems so simple, but what is really happening behind the scenes?

    First of all, your computer communicates with a known DNS (Domain Name System) server to find out where the website can be found on the internet. The DNS server will then return an IP address for the remote server. This can be used to go directly to the website. You can think of the internet as being quite like the planet itself -- we have lots of locations, all over the world. 

    These places all have a street address -- this is akin to the domain name of a website (i.e. tryhackme.com, or google.com); but they also have co-ordinates which can be used to pinpoint their location with absolute accuracy. 

    These co-ordinates are like the IP address of a website. If you know the street address of a location, you can enter it into Google Maps and be given the exact coordinates, which can then be put into a SatNav to take you there with pinpoint accuracy!

    In the same way, your browser is given the address of a website (i.e. tryhackme.com). It sends this address off to a DNS server, which tells it the "co-ordinates" (the IP address) of the site. Your computer doesn't understand the original, human-readable domain name, but it does understand what an IP address is! The IP can then be used to find the server across the internet, allowing your computer to request the content of the website. Of course, in reality, this is a highly simplified analogy, so a more in-depth explanation of this process can be found here.



    Once your computer knows where it can find the target website, it sends something called a HTTP (Hypertext Transfer Protocol) request to the webserver.

    This is just a standard network request, but it is formatted in a way that both your web browser and the server can understand. In practice, this means adding certain "headers" to the request which identify it as a HTTP request, and tell the server a variety of other information about the request, as well as your own browser. Amongst many other headers, HTTP requests always have a method and a target. These specify what to retrieve from the server (the target), and how to retrieve it (the method). The method most commonly used to retrieve information is called the GET method. When sending data to the server, it's more common to use a method called POST.



    HTTP is an inherently stateless protocol. This means that no data persists between connections; your computer could make two requests immediately after each other, and, without relying on separate software, the web server would have no way to know that it was you making both the requests. This begs the important question: if HTTP is stateless, then how do login systems work? The web server must have a way to identify that you have the right level of access, and it can hardly ask you to enter your password every time you request a new page!

    The answer is cookies -- tiny little pieces of information that get stored on your computer and get sent to the server along with every request that you make. Authentication (or session) cookies are used to identify you (these will be very important in your mission today!). The server receives your request with the attached cookie, and checks the cookie to see what level of access you are allowed to have. It then returns a response appropriate to that level of access.

    For example, a standard user should be able to see (but not interact with) our control panel; but Santa should be able to access everything! Cookies are also often used for other purposes such as advertising and storing user preferences (light/dark theme, for example); however, this will not be important in your task today. Any site can set cookies with a variety of properties -- the most important of these for today's task are the name and value of the cookies, both of which will always be set. It's worth noting that a site can only access cookies that are associated with its own domain (i.e. google.com can't access any cookies stored by tryhackme.com, and vice versa).

    It's important to note that cookies are stored locally on your computer. This means that they are under your control -- i.e. you can add, edit, or delete them as you wish. There are a few ways to do this, however, it's most commonly done by using your Browser Developer Tools, which can be accessed in most browsers by pressing F12, or Ctrl + Shift + I. With the developer tools open, navigate to the Storage tab in FireFox, or the Application tab in Chrome/Edge and select the Cookies menu on the left hand side of the console.





    In the above image you can see a test cookie for a website. The important attributes "Name" and "Value" are shown. The name of a cookie is used to identify it to the server. The value of the cookie is the data stored by the server. In this example the server would be looking for a cookie called "Cookie Name". It would then retrieve the value "CookieValue" from this cookie.

    These values can be edited by double-clicking on them, which is great if you can edit a session or authorisation cookie, as this can lead to an escalation of privileges, assuming you have access to an Administrator's authorisation cookie.

    Having read the lengthy dossier,  you get ready to hack your way back into Santa's Christmas Control Centre! You enter the IP address at the top of the screen into your browser search bar and press enter to load the page.



    1) Register for an account, and then login.

    What is the name of the cookie used for authentication?

    HINT :- Check your Browser's Developer tools. These can usually be accessed with F12 in most browsers, or Ctrl + Shift + I otherwise.



    Ans :-  auth

    2) In what format is the value of this cookie encoded?

    HINT :- Often used as a "shorthand for binary".


    Ans :- Hexadecimal



    3) Having decoded the cookie, what format is the data stored in?

    HINT :- Use CyberChef to decode the cookie. The format is a very common one, often linked to JavaScript. (https://gchq.github.io/CyberChef/#recipe=From_Hex('Auto'))


    First of all we will copy this cookies value (session's cookies ) and then decode it in cyberchef website. ( link in the above )




    Check out this format, look like javascript object notation 

    {"company":"The Best Festival Company", "username":"whoiskumaratul"}

    Ans :-  JSON 

    4) Figure out how to bypass the authentication.

    What is the value of Santa's cookie?


    HINT :- Remember, you can edit your cookies value! Why not use the decoded cookie you got in the last question, update the username with "santa" and re-encode it? 


    Now, we will change the value of username, like whoiskumaratul, This is my username, there may be something else in your case. so, You have to re-encode the entire format by typing the Santa username in place of your username.



    {"company":"The Best Festival Company", "username":"whoiskumaratul"}


    {"company":"The Best Festival Company", "username":"santa"}


    let's decode the value in "To Hex" and Delimiter is NONE and Bytes per line is 0.




    Ans :-   7b22636f6d70616e79223a22546865204265737420466573746976616c20436




    5) Now that you are the santa user, you can re-activate the assembly line!

    What is the flag you're given when the line is fully active?


    Now, replace your cookies to the santa's cookies and refresh the page. Then click to enable every Active button.

    See you soon, with another task N day. So till then bookmark our website
