Kali Linux provides many tools for information gathering.

For this post, I am going to introduce whois:

What is Whois? When to use it?

Whois is a widely used Internet record listing that identifies who owns a domain and how to get in contact with them.

The Internet Corporation for Assigned Names and Numbers (ICANN) regulates domain name registration and ownership. Whois records have proven to be extremely useful and have developed into an essential resource for maintaining the integrity of the domain name registration and website ownership process.

How to use Whois?

To discover our IP, type ifconfig 

We were given an assignment and was asked to fulfil the following:

1. Network and IP Space pentest.id
2. Enumeration User hackme.pentest.id
3. Enumeration User Email @pentest.id

 

We were recommended to use the following tools:

1. wpscan
2. jooscan
3. TheHarvester
4. Google
5. Nmap

 

The following is my solution:

 

Network and IP Space pentest.id

I used theharvester to check any hostnames IPs available.
I typed the following in terminal:

 

 No need to worry about the “warning” because it is just telling us that theHarvester does not work in any site that has ssl.

The function of -d is to search for any domain or name of a company.
The function of -b is to choose the data source such as bing, google, twitter, etc.

After typing “theharvester -d pentest.id -b google”, I received the results as the following:

 

Enumeration User hackme.pentest.id

I used wpscan to enumerate user from hackme.pentest.id and typed the following:

” –url ” is used to scan the url of the blog we want to scan.

” –enumerate u ” means enumerating users.

 

It produced the result as the following:

 

Enumeration User Email @pentest.id

I used theharvester and typed “theharvester -d pentest.id -b gooogle”, but unfortunately there was no email found.

Background

Our motive in making this game is that we want to make a game to help high school or middle school students to remember biological terms specifically the human digestive system for the long term. We thought through playing games they can remember biological terms easier and faster than through reading books.

Idea

We use the idea of drag and drop. The user will be shown an unlabeled diagram of the human digestive system, and he will be given seven names. The user will have to drag each name to corresponding box that describes the organ. If his choice is correct, he will get 10 points. For example, the word is “kidney”, and the user will have to place the word in the box that describe the organ “kidney”. Then, the user will be directed to a new page. In this new page, The user will be shown a labeled diagram of the human organ system. If the user click each organ, he will be directed to a page that provide questions for the selected organ. There are seven organs, and the user will have to finish all the seven questions to finish the game.

How to play:

The user will be shown an unlabelled diagram of the human digestive system, and he will be given seven names to choose which are the names of the organ in the human digestive system. The user will have to drag each name to the corresponding box that describes the organ. If he placed the word in the right box, he will get 10 points. Else, he will lose a try. For example, the word is “kidney”, and the user will have to place the word in the box that describe the organ “kidney”. After the user has finished labelling each biological term to its respective organs, the user will be directed to a new page. In this new page, the user will be shown a labelled diagram of the human organ system. If the user clicks each organ, he will be directed to a page that provide questions for the selected organ. There are seven organs, and the user will be given only five tries. If his points are more than 200, he wins the game.

Documentation:

I created the sprites, texts, and buttons. The user will be directed to another layout when he clicks a button. For example, the user clicks the home button, he will be directed to the home layout.

In each sprite, I inserted the DragDrop behaviour. In each sprite, I made instance variables called: start_x_organname and start_y_organname. I created those two instance variables in each sprite so that if the user drags a word and drops it in the wrong box, the word could return to its original position. Basically, if each sprite overlaps with its box, the sprite moves to the position of its box. The system generates a correct sound effect and add 10 points. Else, the sprite will return to its original position and the user will lose a try. I created 2 global variables: Tries and Score. I set initially the tries to be five and the score zero.

Background

Our background motive in making this game store proposal is because we love to play games. As an side effect of that love we also want to understand everything there is to game, from why and how to make one to how to sell or do business with games. On the particular note of doing business, we would like to think and recreate it as realistic as possible the asset management side of a common game store found anywhere in the world.

Idea

The idea of this game store is a store which provide arcade games and also sells console plus pc games, thus the asset of the store must be divided into 2 categories which is arcade and normal games. Plus there would be a “money”,”coin” and ”prizes” categories. The arcade games required a unique coin that needs to be inserted otherwise the game won’t run, therefore the customer has to trade their money for the unique coin that the store already provide. The arcade games also provides different kinds of challenges for the customers and the store will reward the customer who won the challenges by giving them prizes based on the difficulty of the challenges.

Foreign Key arcadeId references arcade (arcadeId) on update cascade on delete cascade

 

• customer (customerId, customer_fName, customer_lName, customer_age, customer_gender, customer_phone, customer_email, customer_address)
• staff (staffId, staff_fName, staff_lName, staff_age, staff_gender, staff_phone, staff_email, staff_address)
