Hello, everyone, and welcome to the bonus section of
the course called tour. And actually, the
last video of this course. Okay, I
want to congratulate you just yet, but
the but believe me when I say that we are near the end of our
little osint journey, so let's go on
and demystified tour.
What is tour? Okay, so I find
a Wikipedia definition may be most relevant tour
is free and open source software for
enabling Anonymous communication. This is one of the
best methods to preserve your online privacy and
to protect your online activities from the eyes of advertisers
governments to criminals like
stalkers and so forth. Then
why is there a picture of an onion here?
And no, this is not a fraudulent fraudulent
course to somehow increase the sales of
onions rather to provide you with an explanation because
the name derives from the original project name,
the onion router, you
know, how the more you peel an onion. The more it
smells. Well here is the analogy torque
tries to anonymize your online activity, by
encasing your traffic in multiple layers of
encryption, then sending it.
A number of nodes that peel
back those layers, one at
a time. And hence the onion nickname. When
you start going through tour, you will surely want to answer a
question. How to access the dark web dark web
resides on the special top-level domain for anonymous onions,
service or hidden service, with
its name, dot onion. Such addresses
are not actual DNS names and
the dot onion TLD.
Is not in the internet, DNS root, but
with the appropriate proxy software installed internet
programs, such as web, browsers can
access sites with the dot onion, addresses by
sending the request through the Tor Network.
Now, I want to show you how the store work
with a simple topology of
a tour communication process. So,
check it out. We the users or Alice
or Joe, or whatever. The name of the end-user on
the left is picks a random path to
the destination server. When when L,
is simply wants to access a website. So
Alice sends a packet and each node decrypts, only
enough information to know where to
Send it next in the Tor Network. So none of
the nodes. Knows both your identity and
the identity of a website or a server that you wish to
reach or Alice. As you can see, the
traffic goes all around encrypted without
a possibility for anyone to know where
you are going. Although this sounds almost
bulletproof. It isn't. And that
is one of the disadvantages of tour at some point. Your
data has to leave the Tor Network to get
Get to your first intended
to destination and that last point of exit is
called the exit node. And that's the very
last node your data travels through at
that moment between the last node and the destination. Your
data isn't necessarily encrypted. And
that is one of the disadvantages of when using Tor, another
disadvantage is speed. So be patient,
when using it downloading and simple
fast. Browsing will take some time. So my
suggestion.
Is don't use it for downloading for downloads or
streaming for streaming high, quality videos, and
other things. Having said that it is still
very difficult to trace. Someone over the Tor Network and
the potential to read through your traffic, has the
operator of the exit node and whatever
side that you're connecting to.
Okay. Now you are probably asking yourself how
to access tour the Tor Network or even browsed the
tour sites, a
very simple ways. The Tor Browser that is provided by the tour
foundation for free. You can find it on
the tour, project.org /downloads webpage
and you have a possibility to use it
in almost all the flavors of any operating system.
This is a modified version of
Firefox browser that
Other things tries to use the most secure connections when
browsing again remember https
everywhere. Plug-in we talked about when
preparing our oceans environment. Please
be aware that any app or a plug-in probably won't
work when using a Tor Network by default and
then there is a good possibility that
your identity could get leaked through
an IP address or some other personal information by
using those unprotected plugin.
Yes.
Also, please check out the tour documentation tab on the
Tor project to website because there is a plethora of
information about it there.
Stormy night doorman, not
be perfect. But it is a good first step to
protecting your privacy and is a
good tool as well. As for the good guys, like
researchers, cyber defense professionals activist,
privacy of are persons and
unfortunately for the bad guys, like cybercriminals stalkers
and other bad people go
on and try it out. Actually try accessing
regular websites and some flavors.
Of what my P service so
you can see what IP address you get to win using the
Tor Browser. It should the IP should
change randomly every few moments.
And now why did I tell all this about tour?
Or explain anything about it
the about the internal structure, the Deep Web dark
web and all that stuff. Because surely at some point
in your ultimate investigations, you will go looking
for some data and information on those Services. Remember
I said that the visible internet makes up
only about 4% of the whole internet structure. That's
a really small number.
I hope you got a
And now, I hope you get a little bit familiar with the data breach and
leaks concept, but also with the internet structure
and the usage of the Tor software in
the end in the next action. Actually, a
video in is dedicated to our conclusion of
this course. So, in the next video, I will give you
my final Thoughts with some suggestions, where to
go next with your ocean studies. See you there.
