Next I would like to show you LinkedIn bridge database.
Now, the reason why I'm showing you these databases is because almost every single person has either
a Facebook account, Twitter account, or LinkedIn account, or maybe a Snapchat account.
So you, as an Osint investigator or an ethical hacker, can get advantage of these databases to find
even more information about a person.
So in 2012, LinkedIn has suffered from a data breach which resulted in leaking their database that
contain over 160 million email addresses.
And this database contained member IDs, emails and password.
But the version that you are going to download it contain only member IDs and emails, and does not
contain any password.
So to download this database that only contain member IDs and emails, all you have to do is just to
go to this URL that I'm going to put it in the resources of this lecture, and then click on seven zip
and you will download a file that is 1.7GB.
You want to keep in mind that this database occurred in 2012.
So if somebody has created their LinkedIn account in 2013, 2014, etc., then you won't be able to
find their account in this database.
Only accounts that are older than 2012 could be found in this bridge database.
Now after downloading this database you want to extract it by right mouse click and then say extract
all.
And this will create a folder called Li users.
So let me go to my LinkedIn.
And I have already searched for Rishi Kabra and wasn't able to find his account in this bridge database
because I believe that he created his account after 2012.
So I'm going to search for this person.
So the first thing we need is this person's member ID to find the member ID of any LinkedIn account,
right mouse click and then view page source.
And then I'm going to hold the Ctrl and F keys and then search for the word member.
And then I'm going to click on the up arrow.
And here is the member ID of this person.
So I'm going to copy it and paste it in my notepad like this.
And then I'm going to go to the database that I have downloaded.
So right mouse click and then click on Agent Transact.
And then I'm going to search for this user or member ID and then click on start.
Now this could take a while as I said before because this is a five gigabytes file.
And as you can see we were able to find the match.
So this is the email address that is associated with this person.
So it is a company email address.
Paris healthcare.
So let me go to his page to see if this is actually or he worked at this place.
Let me scroll down.
And you can see here that he was the marketing director of Paris Healthcare, and this is his business
email address.
Sometimes you will be able to find personal email addresses and not only corporate or companies email
addresses.
So in this video, you have learned how to download LinkedIn database and how to search within this
database by member ID to find the person's email address.
And please keep in mind that this data breach occurred in 2012, which means that you will not be able
to find all accounts.
But I think that this database is still helpful to find more information about a person.
