2.Fake Hotspots, sometimes a hacker can use a fake wi-fi hotspot to get into your device.

3.Websites taking private Info, some malicious websites ask for information about you, like your name, age, and other private info. What they sometimes do is take the private information and use it to their advantage

4.Doxing, the term "Doxing" refers to an act of a person sending out personal information about a victim and posting it in the internet for all to see. The information usually contains home location, age, name, security number, personal pictures, passwords and many more.

5.Ransomware, Ransomware is when a hacker puts malware into a computer and locking all features until a ransom is paid. This is done by a victim accidentaly clicking on a malicious link.

So, Why does Security matter?

Security matters, because we all need a time to our selves alone. Without security our society would not function, without security we'd all know everything about each other, things that we might not want other people to know.

Monday Questions

What is Illegal About Free TV Android Box?

To my understanding, Android Box is not illegal because they are not downloading the movies, they are streaming them. Although this is not illegal, I think Android Boxes should be illegal because you buy the product once and you never have to pay any monthly bills ever again, you also don’t have to pay for any movies, this is considered piracy because they do not pay for the movies being shown.

How is Netflix trying to stop online piracy?

Currently, Netflix has a team of people that search the internet and take down sites that stream their exclusive content. They are doing this by making piracy a taboo or an uncool act.
