Directions: Write advertising copy according to the instructions below.

Houses usually don't just sell themselves. People sell them. And most of the time people doing the selling are real estate agents. For the most part, realty people attract buyers to houses by writing eye-catching advertisement in the classified section of the newspaper.

1. Choose a house as the subject of an advertisement. But rather than writing a brief ad for the classified pages, make your ad much longer for a monthly real estate magazine.
2. Your advertisement should contain at least three paragraphs with a minimum of 5-7 sentences each. Be certain to use correct capitalization, punctuation and paragraph form.

How hacker hack password 

WSCube Tech has brought video for you on wifi password cracking and securing its password. Ashish Kumar explains how to crack and secure the passwords of our networks. He explains how the entire setup logically that how we are going to hack the wifi or how it is working. With the help of Cap Extension which is for capturing files, all the data in the handshake file will be saved in our system. And anyone can crack this. Cap file from any place. The password is there in this file and you just have to crack it. Apart from this, there are many other techniques. If we press enter then our wireless device is down now. We have to convert its mode to monitor mode. We will make wlan0 up again. And the opposite of down is up, which means that we are starting wireless device. I think that now, everything will be perfect. We'll select any 1 interface or essid or hotspot and we will perform wifi cracking method on that.

We have the mac address or bssid of the wscube tech hotspot. And we can see in ch that its working on channel number 11. Here only, I will try to do proper sniffing or intercept the proper data. And I will also see how I can capture handshake file in sniffing. We can get handshake file in only 2 cases. When a new user is connecting or if we disconnect any old user for some time and for sure, that user will automatically send the handshake file to get connected. And whenever we go to that wifi range again, automatically that password goes to get applied in the wifi and we get auto connected. This function of autoconnection which will become a vulnerability here. The option is "a" in which I am telling the mac address of our main wifi or hotspot, i.e. tech. It means that in this, we tell whom to disconnect from which user. The main user which is the hotspot of ws cube tech, I will give its mac address in "a" option. And after that, we have told the name of the interface through which we have to do the activity. So, we will remove this from here. And now we want the mac. address of the client that we have to disconnect so that it should send the handshake file again to get connected.In this video, the instructor explains how to crack a password using aircrackng. He starts by discussing a common passwords list, which many places will accept as authentication. If the password doesn't work, he explains how to make a better list. He then goes on to talk about how aircrack-ng works and how fast it is. The instructor finishes the video by saying that he hopes everyone enjoyed it and that they will come back for the next one.
