Welcome to Section 11 and this section, we're going to go over mobile phone security, this is essentially
a section here that is going to give you an overview of how you can protect your phone, how you can
go about hacking different phones.
Right.
Because remember, we always want to look at things from the hackers perspective, from the black hackers
perspective, and then also understanding how they would go about attacking a phone so we can also keep
our own phones safe and secure as well, as well as some different tools and techniques to ultimately
keep your phone as safe as possible.
So let's go ahead and jump in here.
Section 11, we're going to be going over mobile phone networks and operating systems and then mobile
attack vectors.
What exactly those are and how those come into play and then mobile malware.
This is very important here because these can take over your cell phones and actually cause quite a
bit of damage and then mobile hacking using you URLs and then the mobile platform vulnerabilities and
countermeasures and then jailbreaking and routine considerations, privacy issues due to geolocation
and then finally mobile phone data security.
So there's a lot to be covered here.
I'm going to give you a quick overview of this section, and then Anthony's going to be walking you
through a lot more in-depth in the individual lecture.
So let's go ahead and look at the mobile phone network, especially in today's day and age.
Everybody has a cell phone, right?
You have kids, you have teenagers, you know, in elementary school that are getting cell phones and
are on cell phones pretty much every single day, especially now with adults, with individuals.
I mean, our attention spans are so, so low because we're on our phones.
Right.
Pretty much 24/7.
And the big thing here is to understand that having our cell phones is very important to the average
person in the majority of phones are connected to a 4G network.
So whatever service provider you have, you know, whether whether it be Sprint, Verizon, T-Mobile,
you know, whatever that may be, you're typically going to be on a 4G network in the way that you're
connected to a wireless phone network is the device, which is typically known as a terminal, uses
radio frequencies to communicate with the base station.
So when you're near a particular tower, you are essentially emitting radio frequency waves from the
phone in order to be able to communicate with those stations.
And so depending on your location, whatever tower or base station that you're next to, you're going
to be meeting those radio frequency waves and they're going to be bouncing off of that base station
and then being able to be connected to that 4G network so you can actually use your phone and also the
Internet.
And so as we go deeper into the mobile phone networks, understanding how to hack into mobile phones,
it's really important for you to get this foundational understanding of how mobile phone networks work.
You know, the foundational elements here and essentially what the 4G network is really about.
So now let's look at mobile phone operating systems.
Now, there are two main operating systems for mobile devices.
There's no one, the Android from Google.
This is where you have your Samsung phone, Motorola phone, Google phone.
Right.
Those are going to be the ones that you're using the Android on.
Right.
And this is where you can essentially use your phone to play games, to call people to text and whatever
other applications you have there.
Now, iOS from Apple, this is going to be their specific operating system as well.
And this operating system is typically used through the different iPhone, iPad and iPod as well.
Same thing with Google for the most part.
When you have Android, they're going to be typically running on the tablets as well.
And one of the key pieces of information here that I want you to understand is that Apple has been known
previously for being the leader in mobile security.
Right.
A lot of people say, hey, you know, iOS, Apple phones, Apple technology, very difficult to break
into.
And that has been the case for quite some time.
However, according to a recent article by Senate, Android is actually gaining ground.
So there's a lot more technology that's becoming available.
Android is stepping up as hackers are getting more sophisticated.
So is Android as well.
OK, so let's talk about social engineering with mobile phones.
So now I want to give you an example of this.
Let's suppose that you receive a text message, right, from an unknown number, and that number is
telling you that you've won some sort of prize.
And in order for you to get that prize, all you need to do is reply back with your name, email account
and any other.
A personal information, maybe your cell phone number or perhaps your last four of your social rank.
This is where a lot of people get taken advantage of here because they are just trusting out of nowhere
blindly this message that they're receiving from some unknown source.
Right.
And so this is where you need to be very, very wary of here as far as text messages coming from unsolicited
or just numbers out of the blue.
Right.
So very important to be aware of that, because this is where people get oftentimes taken advantage
of.
And I've received these kind of messages in the past as well.
And typically I just delete them or I reply back with staff or just pretty much don't do anything about
it.
Because what's going to happen is if you click on the link or if you reply back with any information,
they're going to be able to get access to maybe your cell phone or just your information alone.
If you respond back with your name, email or phone number, whatever, they're going to be able to
have access to that and be able to use that to their advantage.
And so what I want to show you now is I want to show you this text message down here that I got the
other day.
And as you can see here, this is a text message from some sort of secret shopper program or whatever,
and it was out of the blue.
I never signed up for any kind of program or whatever like that.
As far as inputting my information to learn more about this, it pretty much sent me a message.
I don't know what we're talking about.
I can earn some extra money.
Right?
Six hundred dollars a week.
And that it wouldn't affect my job or wouldn't affect me, whatever.
Right.
And so you think about it, both of these links here, if you click on them, could give you some sort
of Trojan, could give you some sort of virus malware.
Right.
And also could lead you to go to a website where they could steal your information.
So this is where you want to be very, very careful.
There are thousands of people that unfortunately get taken advantage of because they're blindly trusting
people that are just sending them messages or text messages or whatever that may be.
And they're not doing their proper research.
Right.
So very important that when you're receiving these types of messages that you do your homework, you
research the company, whoever's sending you a message because you're going to get taken advantage of
if you do not now.
And let me give you another example.
So one of the other types of messages that I received in the past is where the individual, the hacker,
may have access to somebody's stolen credit card information.
So just out of the blue, they're sending me this message.
You're telling me, hey, I will pay you for you to build me a website.
And do you accept credit card?
Right.
And it's just some number out of nowhere, out of the blue.
And so those are the kinds of messages and things you want to be on the lookout for.
Essentially, if it sounds too good to be true, it often is too good to be true.
So make sure to keep that in mind.
Let's go over some of the most common phone hacking methods, phishing.
So this is where you're lowering your target with fake versions of legitimate sites to extract credentials.
So think about the last text message that we just looked at.
They have very specific links on there.
They have your URL Shawna's and that link or those links could actually lead to a website, a fake version
of a legitimate site, and it can actually extract your information.
So very, very important to be very careful to do your research and not just blindly click on the links
or messages that are received.
And then we have control message attacks.
This involves sending a control message on the device that you want to hack.
This allows you to get access to the settings menu of the targeted cell phone.
So this is like if you were to receive a message saying, hey, this is Verizon or this is T-Mobile,
you need to update your phone and you need to get it to the newest version.
And then what ends up happening is you click the button or whatever or click the link and your phone
gets updated.
But what happens is you get malicious type of information, maybe some sort of malware or a virus on
your phone.
OK, so very important to look out for these as well.
And then probably the most common one here is the spam messages.
So this is where hackers are getting access to a victim's Google account.
Now, Google accounts are very, very important here because oftentimes people will have like a Gmail
account, right, that they sign up with, do all their online shopping, maybe Amazon, maybe they
have it connected to their bank account, to their social media accounts.
And oftentimes when you are able to get access to these, you don't need a security code if you have
the password to the Google account.
So very important to make sure that any messages that are coming out of the blue out of nowhere, that
you're not just blindly clicking them, you're making sure and verifying that it's indeed from the actual
sender and that you're not.
Getting taken advantage up here, so this is a very quick and short section overview here for Section
11.
I wanted to give you an understanding of what exactly phone networks are, how they function, the different
mobile operating systems, and then some of the common methods that are used to hack phone Anthony is
actually going to dig a whole lot deeper into mobile phone hacking, how to protect your phone, how
to keep your phone secure in this section here.
So I'm excited for you to get started and look forward to seeing you on the next one.
