After finding someone's personal or business email address.
The next step is to gather information about this email address.
So if you have got an email address and you don't know to which person this email address belongs to,
then you can perform the techniques that I'm going to talk about in this section.
You might also be able to gather information about the location of the person who is using this email
address.
So the first method that I would like to cover is use search operators to check whether an email address
is indexed by search engines or not.
For example, here I have searched for z at z security.org on Google and were able to get a search result.
Now obviously this is a business email address and it's very expected to find it on search engines.
But there are many cases in which I were able to find someone's email in other websites.
And these websites helped me to narrow down my search.
Now let me show you a real life example.
So far we have gathered two email addresses.
This is the first one.
Rishi Kapoor 132 at gmail.com that we were able to find it in this document on Google.
And this is the second email address that we found it on his Twitch account.
So what I always like to do is just to copy the email address and then go to Google and put it within
two quotation marks and then hit enter.
And here we have got two search results, as you can see here.
And the email address is or has been found in this document.
So let me open this document.
As you can see here is Rishi Kabra email address.
And this is his name.
And this is the document that he wrote I believe.
So in this case I can copy the title of this document.
And then you want to go to Google and put this title within two quotation marks.
And then I'm going to hit enter, because this might provide me with any additional information.
So we have already got these two search results on Google by performing the previous search.
But if we scroll down a little bit we can see the university name where Rishi Kabra has studied.
So I can open this website and then scroll down and see the people or the supervisors of this publication
or document.
Now for me this is not very important, but what's actually important is that if this person didn't
have a LinkedIn account and they didn't post that, they studied at the SRM University.
Now, I know that they have studied at this university, and I can go to search engines and search for
his name and this university, and I might get a search result.
In our case, we already know that he studied at the SRM University.
This is the PDF file that I have downloaded from his LinkedIn account.
But in case the person didn't have a LinkedIn account and they have a very popular name, then you can
search for the university name and their name on search engines.
So I can say SRM University like this and then say Rishi Kabra and then hit enter and then we will get
less search results.
Now let's search for the second email address which is his gaming email address.
I'm going to copy it and then go to Google and then search for it.
And as you can see we have got only one search result, which seems to be his YouTube channel.
So here is his YouTube channel with the same logo that we have found on his Twitter account.
And this is his email address.
We can also find additional information like his Twitch account, just in case we didn't have his Twitch
account.
Now we have it because he has linked it to his YouTube channel.
Now you want to keep in mind to search for this same email on other search engines like Bing or Yandex.
So if we have searched for Rishi Kalra at gmail.com on Yandex, we will probably get a search result.
So as you can see, we have got some search results.
Let me put it within two quotation marks.
And now we only got two search results, one on GitHub and the second one in the document that we have
already saved in our notes.
One more thing that I would like to show you, which is if you have someone's email like this, I always
like to remove the domain name and then search for the first part of the email on search engines.
Now, we already know that Rishi Kabra uses this username on multiple accounts, But in case someone
has a very unique email address, then you can search for the first part of the email on search engines
so we can copy it and put it on Google, etc. as you can see.
So in this lecture, you have learned how you can utilize search operators to find whether an email
address is indexed by search engines or not, and how to search for the first part of an email address
on Google or any other search engine to find if there are any accounts that uses the first part of the
email as a username.
Now you want to keep in mind that this is not going to work all the time, because if the person is
not active online, then they will obviously have nothing on the internet that they have posted.
So this sometimes works and sometimes doesn't work, but I think that it's always good to give it a
try, because you might be able to find information that you will not be able to find otherwise.
