00:00:00,650 --> 00:00:01,670
Hey, guys, welcome back.

2
00:00:02,120 --> 00:00:07,270
So in this lecture, we are going to learn the basics or we can say the theoretical part of this course.

3
00:00:07,720 --> 00:00:11,330
OK, so as you can see on the screen, it's a nice book, right?

4
00:00:12,110 --> 00:00:16,840
For some time, let's imagine it as a diagram of the whole Internet, like from top to bottom.

5
00:00:17,480 --> 00:00:22,090
So the tip of the iceberg, as it can be seen again, denoted as the surface web.

6
00:00:22,280 --> 00:00:26,020
And as we can say that five percent of the whole Internet is this off as well.

7
00:00:26,570 --> 00:00:29,700
Let's say we are on the surface of the water or whatever.

8
00:00:29,720 --> 00:00:35,120
OK, so from the surface, you can clearly see this office web that is the tip of the iceberg.

9
00:00:36,110 --> 00:00:41,550
We can partially see the midsection of those, but that section can be denoted as there are.

10
00:00:41,650 --> 00:00:44,690
Can we say that 90 percent of the Internet is there deep?

11
00:00:45,860 --> 00:00:51,160
And that remains the end point of this book or the darkest point of which cannot be seen from this office,

12
00:00:51,620 --> 00:00:57,530
this totally hidden point of the Web or the Internet can be downloaded, as Zadok of the Dark Web,

13
00:00:57,800 --> 00:01:01,150
same as this office web occupies five percent of the Internet.

14
00:01:01,460 --> 00:01:04,460
And simple was the visible part of the Internet here.

15
00:01:04,460 --> 00:01:06,650
By invisible, I mean easily accessible.

16
00:01:07,040 --> 00:01:10,040
So the easily accessible part of the Internet is this office web.

17
00:01:10,400 --> 00:01:16,760
The partially visible area can be called as a deep web and a totally dark or the hidden area of the

18
00:01:16,760 --> 00:01:18,800
Internet can be called the dark web.

19
00:01:19,490 --> 00:01:25,620
So this office web is easily accessible by the browsers like Chrome, Mozilla, Firefox or Better or

20
00:01:25,640 --> 00:01:26,120
Safari.

21
00:01:26,540 --> 00:01:31,760
We can find websites such as Amazon or YouTube, Wikipedia and even Facebook on this off as well.

22
00:01:32,450 --> 00:01:37,970
Talking about the deeper we can see that there are deep web is unindexed or in simple words.

23
00:01:38,330 --> 00:01:41,690
The deep web is not shown by any kind of browsers like Google.

24
00:01:42,440 --> 00:01:47,050
BBM includes anything behind a paywall or required sign in credentials.

25
00:01:47,570 --> 00:01:54,110
It also includes any content that its owner have blocked the web crawlers from indexing like medical

26
00:01:54,110 --> 00:01:59,350
records, fee-based content, membership, Web site and confidential corporate Web pages.

27
00:01:59,510 --> 00:02:02,450
So in short, the Deep Web cannot be directly accessed.

28
00:02:02,810 --> 00:02:05,570
It can be seen as a locked part of the Internet.

29
00:02:06,140 --> 00:02:08,990
Unlike before taking a Netflix subscription.

30
00:02:09,050 --> 00:02:12,940
You are on the Netflix website located on that service web.

31
00:02:13,340 --> 00:02:19,070
When you buy the subscription, you are given an email and a password Betaworks as a giving you access

32
00:02:19,070 --> 00:02:23,770
to the Netflix data located on there before moving to the Dark Web section.

33
00:02:23,820 --> 00:02:29,030
We can say that the Dark Web is the subset of their deep web, which is intentionally done.

34
00:02:29,270 --> 00:02:36,160
It can be accessed only by using a specific browser, but actually no one really knows the size of the

35
00:02:36,170 --> 00:02:36,680
Dark Web.

36
00:02:36,680 --> 00:02:42,890
But most estimates put it around five percent of the total Internet after briefly learning about the

37
00:02:42,890 --> 00:02:43,440
dark web.

38
00:02:43,490 --> 00:02:48,570
One question arises why do we actually need to document what is the problem with this office web?

39
00:02:49,310 --> 00:02:53,050
So there are many points which can be considered as the answer of this question.

40
00:02:53,520 --> 00:02:58,820
Well, because some of them briefly, first of all, to understand the importance of the dark web,

41
00:02:58,820 --> 00:03:05,830
let's quickly talk about the history of the document and computer network known as ARPANET ERP and the

42
00:03:06,410 --> 00:03:12,890
Advanced Research Projects Agency network was developed in the early 60s for better communication between

43
00:03:12,890 --> 00:03:13,490
computers.

44
00:03:14,090 --> 00:03:19,700
During the time of Cold War, the government started using it for security purposes, mainly dealing

45
00:03:19,700 --> 00:03:22,250
for the biggest factor of security.

46
00:03:22,250 --> 00:03:24,160
Here was again anonymity.

47
00:03:24,470 --> 00:03:31,190
Order was launched for public use in late 90s and due to the anonymity factor, it gained interest among

48
00:03:31,190 --> 00:03:31,580
people.

49
00:03:32,360 --> 00:03:36,740
It was mainly used for visiting a bank, website or service in a particular state or country.

50
00:03:37,160 --> 00:03:42,280
Like in some countries, Facebook is banned, but people can access the Facebook wasn't on the dark

51
00:03:42,320 --> 00:03:44,720
web without without being identified.

52
00:03:45,230 --> 00:03:47,120
Which takes us to our second point.

53
00:03:47,150 --> 00:03:50,180
Internet freedom, surfing the Internet.

54
00:03:50,510 --> 00:03:53,660
There are possibilities that you are being tracked even by the government.

55
00:03:53,660 --> 00:03:59,180
Sometimes the websites with your digital footprint is being tracked in Google tracks.

56
00:03:59,180 --> 00:04:01,220
It totally violating your privacy.

57
00:04:01,760 --> 00:04:03,620
Well, that's where their dark web comes.

58
00:04:04,040 --> 00:04:09,980
Total anonymity can give you full access, like right of thought or right of speech on the Internet.

59
00:04:10,610 --> 00:04:12,410
The next point would be anonymity.

60
00:04:12,710 --> 00:04:14,990
The Dark Web keeps you totally anonymous.

61
00:04:15,440 --> 00:04:18,950
Your digital footprint or the transaction details cannot be tracked.

62
00:04:19,310 --> 00:04:20,810
And that's super awesome.

63
00:04:21,590 --> 00:04:22,850
What will you find on the document?

64
00:04:22,890 --> 00:04:26,300
Well, sadly, a majority of the dark web is filled with illegal stuff.

65
00:04:26,690 --> 00:04:33,290
You can buy credit card numbers, all manners of drugs, guns, counterfeit money, stolen subscription

66
00:04:33,290 --> 00:04:39,380
credentials, hacked Netflix account software that help you break into people's computers and many more

67
00:04:39,740 --> 00:04:44,570
you can easily by login credentials of all fifty thousand dollars bank account.

68
00:04:44,990 --> 00:04:51,200
When Bank of America for five hundred dollars you can get three thousand dollars in counterfeit twenty

69
00:04:51,200 --> 00:04:53,720
dollars bills for six hundred dollars only.

70
00:04:54,500 --> 00:05:00,800
You can even buy seven prepaid debit cards or even PayPal account each with two thousand five hundred

71
00:05:00,800 --> 00:05:04,280
dollars balance for five hundred dollars a lifetime.

72
00:05:04,280 --> 00:05:07,430
Netflix premium account goes for dollar six.

73
00:05:07,820 --> 00:05:10,580
You can even hired hackers to attack computers for you.

74
00:05:11,090 --> 00:05:17,780
You can even buy fake identity cards like passports to create a completely new and unique idea of yourself.

75
00:05:18,440 --> 00:05:23,550
But majority of the service providers are scammers, so don't ever, ever fall for this.

76
00:05:24,050 --> 00:05:26,360
Plus, this is only for educational purposes.

77
00:05:26,360 --> 00:05:31,400
So I do not recommend anybody to go searching or opting for this type of services.

78
00:05:32,060 --> 00:05:35,010
On the positive side, not everything is illegal.

79
00:05:35,210 --> 00:05:37,460
The Dark Web also has a legitimate side.

80
00:05:37,670 --> 00:05:43,360
For example, you can join a chess club or a black book or even a social network described as Facebook

81
00:05:43,610 --> 00:05:44,140
after all.

82
00:05:44,780 --> 00:05:45,010
So.

83
00:05:45,460 --> 00:05:46,450
That's it for this lecture.

84
00:05:46,660 --> 00:05:47,710
See you in the next one.

85
00:05:48,070 --> 00:05:48,880
Thank you very much.
