00:00:00,080 --> 00:00:04,040
Next I would like to show you LinkedIn bridge database.

2
00:00:04,070 --> 00:00:10,370
Now, the reason why I'm showing you these databases is because almost every single person has either

3
00:00:10,370 --> 00:00:16,190
a Facebook account, Twitter account, or LinkedIn account, or maybe a Snapchat account.

4
00:00:16,190 --> 00:00:23,810
So you, as an Osint investigator or an ethical hacker, can get advantage of these databases to find

5
00:00:23,810 --> 00:00:26,690
even more information about a person.

6
00:00:27,320 --> 00:00:35,300
So in 2012, LinkedIn has suffered from a data breach which resulted in leaking their database that

7
00:00:35,300 --> 00:00:39,410
contain over 160 million email addresses.

8
00:00:39,440 --> 00:00:44,510
And this database contained member IDs, emails and password.

9
00:00:44,540 --> 00:00:51,860
But the version that you are going to download it contain only member IDs and emails, and does not

10
00:00:51,860 --> 00:00:53,600
contain any password.

11
00:00:53,900 --> 00:01:00,780
So to download this database that only contain member IDs and emails, all you have to do is just to

12
00:01:00,810 --> 00:01:07,860
go to this URL that I'm going to put it in the resources of this lecture, and then click on seven zip

13
00:01:07,860 --> 00:01:12,060
and you will download a file that is 1.7GB.

14
00:01:12,420 --> 00:01:16,050
You want to keep in mind that this database occurred in 2012.

15
00:01:16,050 --> 00:01:23,280
So if somebody has created their LinkedIn account in 2013, 2014, etc., then you won't be able to

16
00:01:23,280 --> 00:01:25,680
find their account in this database.

17
00:01:25,710 --> 00:01:31,140
Only accounts that are older than 2012 could be found in this bridge database.

18
00:01:31,170 --> 00:01:39,090
Now after downloading this database you want to extract it by right mouse click and then say extract

19
00:01:39,090 --> 00:01:39,570
all.

20
00:01:39,570 --> 00:01:43,290
And this will create a folder called Li users.

21
00:01:43,320 --> 00:01:45,900
So let me go to my LinkedIn.

22
00:01:46,710 --> 00:01:52,500
And I have already searched for Rishi Kabra and wasn't able to find his account in this bridge database

23
00:01:52,500 --> 00:01:56,670
because I believe that he created his account after 2012.

24
00:01:56,670 --> 00:01:59,990
So I'm going to search for this person.

25
00:01:59,990 --> 00:02:07,730
So the first thing we need is this person's member ID to find the member ID of any LinkedIn account,

26
00:02:07,730 --> 00:02:11,180
right mouse click and then view page source.

27
00:02:12,140 --> 00:02:18,590
And then I'm going to hold the Ctrl and F keys and then search for the word member.

28
00:02:19,190 --> 00:02:21,740
And then I'm going to click on the up arrow.

29
00:02:22,580 --> 00:02:25,310
And here is the member ID of this person.

30
00:02:25,310 --> 00:02:31,460
So I'm going to copy it and paste it in my notepad like this.

31
00:02:31,460 --> 00:02:35,210
And then I'm going to go to the database that I have downloaded.

32
00:02:35,750 --> 00:02:39,980
So right mouse click and then click on Agent Transact.

33
00:02:40,730 --> 00:02:47,180
And then I'm going to search for this user or member ID and then click on start.

34
00:02:47,210 --> 00:02:52,370
Now this could take a while as I said before because this is a five gigabytes file.

35
00:02:52,640 --> 00:02:56,060
And as you can see we were able to find the match.

36
00:02:56,060 --> 00:03:00,840
So this is the email address that is associated with this person.

37
00:03:01,080 --> 00:03:04,080
So it is a company email address.

38
00:03:04,110 --> 00:03:05,850
Paris healthcare.

39
00:03:05,850 --> 00:03:11,220
So let me go to his page to see if this is actually or he worked at this place.

40
00:03:11,490 --> 00:03:13,200
Let me scroll down.

41
00:03:13,920 --> 00:03:21,810
And you can see here that he was the marketing director of Paris Healthcare, and this is his business

42
00:03:21,840 --> 00:03:22,920
email address.

43
00:03:23,400 --> 00:03:29,640
Sometimes you will be able to find personal email addresses and not only corporate or companies email

44
00:03:29,640 --> 00:03:30,480
addresses.

45
00:03:31,140 --> 00:03:38,640
So in this video, you have learned how to download LinkedIn database and how to search within this

46
00:03:38,640 --> 00:03:43,380
database by member ID to find the person's email address.

47
00:03:43,380 --> 00:03:49,800
And please keep in mind that this data breach occurred in 2012, which means that you will not be able

48
00:03:49,800 --> 00:03:51,570
to find all accounts.

49
00:03:51,570 --> 00:03:57,510
But I think that this database is still helpful to find more information about a person.
