1 00:00:00,200 --> 00:00:04,220 After finding someone's personal or business email address. 2 00:00:04,220 --> 00:00:08,930 The next step is to gather information about this email address. 3 00:00:09,590 --> 00:00:14,630 So if you have got an email address and you don't know to which person this email address belongs to, 4 00:00:14,660 --> 00:00:19,310 then you can perform the techniques that I'm going to talk about in this section. 5 00:00:19,790 --> 00:00:26,270 You might also be able to gather information about the location of the person who is using this email 6 00:00:26,270 --> 00:00:26,930 address. 7 00:00:28,010 --> 00:00:35,390 So the first method that I would like to cover is use search operators to check whether an email address 8 00:00:35,420 --> 00:00:38,120 is indexed by search engines or not. 9 00:00:38,630 --> 00:00:46,490 For example, here I have searched for z at z security.org on Google and were able to get a search result. 10 00:00:46,520 --> 00:00:51,980 Now obviously this is a business email address and it's very expected to find it on search engines. 11 00:00:51,980 --> 00:00:57,860 But there are many cases in which I were able to find someone's email in other websites. 12 00:00:57,860 --> 00:01:02,010 And these websites helped me to narrow down my search. 13 00:01:03,030 --> 00:01:05,550 Now let me show you a real life example. 14 00:01:05,550 --> 00:01:08,580 So far we have gathered two email addresses. 15 00:01:08,580 --> 00:01:09,900 This is the first one. 16 00:01:09,900 --> 00:01:15,600 Rishi Kapoor 132 at gmail.com that we were able to find it in this document on Google. 17 00:01:15,900 --> 00:01:21,120 And this is the second email address that we found it on his Twitch account. 18 00:01:21,390 --> 00:01:27,690 So what I always like to do is just to copy the email address and then go to Google and put it within 19 00:01:27,690 --> 00:01:30,540 two quotation marks and then hit enter. 20 00:01:30,720 --> 00:01:35,340 And here we have got two search results, as you can see here. 21 00:01:35,340 --> 00:01:40,230 And the email address is or has been found in this document. 22 00:01:40,530 --> 00:01:42,660 So let me open this document. 23 00:01:42,660 --> 00:01:45,960 As you can see here is Rishi Kabra email address. 24 00:01:45,960 --> 00:01:47,310 And this is his name. 25 00:01:47,310 --> 00:01:50,910 And this is the document that he wrote I believe. 26 00:01:50,910 --> 00:01:55,260 So in this case I can copy the title of this document. 27 00:01:55,260 --> 00:02:00,660 And then you want to go to Google and put this title within two quotation marks. 28 00:02:00,660 --> 00:02:06,510 And then I'm going to hit enter, because this might provide me with any additional information. 29 00:02:06,750 --> 00:02:12,810 So we have already got these two search results on Google by performing the previous search. 30 00:02:12,810 --> 00:02:19,680 But if we scroll down a little bit we can see the university name where Rishi Kabra has studied. 31 00:02:20,100 --> 00:02:28,320 So I can open this website and then scroll down and see the people or the supervisors of this publication 32 00:02:28,320 --> 00:02:29,460 or document. 33 00:02:29,760 --> 00:02:36,390 Now for me this is not very important, but what's actually important is that if this person didn't 34 00:02:36,390 --> 00:02:42,660 have a LinkedIn account and they didn't post that, they studied at the SRM University. 35 00:02:42,690 --> 00:02:49,140 Now, I know that they have studied at this university, and I can go to search engines and search for 36 00:02:49,140 --> 00:02:53,400 his name and this university, and I might get a search result. 37 00:02:53,880 --> 00:02:57,700 In our case, we already know that he studied at the SRM University. 38 00:02:57,730 --> 00:03:01,630 This is the PDF file that I have downloaded from his LinkedIn account. 39 00:03:01,630 --> 00:03:07,600 But in case the person didn't have a LinkedIn account and they have a very popular name, then you can 40 00:03:07,600 --> 00:03:11,440 search for the university name and their name on search engines. 41 00:03:11,950 --> 00:03:21,760 So I can say SRM University like this and then say Rishi Kabra and then hit enter and then we will get 42 00:03:21,760 --> 00:03:23,230 less search results. 43 00:03:23,740 --> 00:03:28,600 Now let's search for the second email address which is his gaming email address. 44 00:03:28,630 --> 00:03:35,680 I'm going to copy it and then go to Google and then search for it. 45 00:03:36,490 --> 00:03:42,220 And as you can see we have got only one search result, which seems to be his YouTube channel. 46 00:03:44,260 --> 00:03:50,590 So here is his YouTube channel with the same logo that we have found on his Twitter account. 47 00:03:50,590 --> 00:03:53,740 And this is his email address. 48 00:03:54,040 --> 00:04:00,070 We can also find additional information like his Twitch account, just in case we didn't have his Twitch 49 00:04:00,100 --> 00:04:00,610 account. 50 00:04:00,640 --> 00:04:04,690 Now we have it because he has linked it to his YouTube channel. 51 00:04:04,870 --> 00:04:11,200 Now you want to keep in mind to search for this same email on other search engines like Bing or Yandex. 52 00:04:11,200 --> 00:04:18,580 So if we have searched for Rishi Kalra at gmail.com on Yandex, we will probably get a search result. 53 00:04:19,120 --> 00:04:21,700 So as you can see, we have got some search results. 54 00:04:21,730 --> 00:04:24,250 Let me put it within two quotation marks. 55 00:04:25,300 --> 00:04:31,600 And now we only got two search results, one on GitHub and the second one in the document that we have 56 00:04:31,600 --> 00:04:33,520 already saved in our notes. 57 00:04:33,910 --> 00:04:39,130 One more thing that I would like to show you, which is if you have someone's email like this, I always 58 00:04:39,130 --> 00:04:46,570 like to remove the domain name and then search for the first part of the email on search engines. 59 00:04:46,600 --> 00:04:53,370 Now, we already know that Rishi Kabra uses this username on multiple accounts, But in case someone 60 00:04:53,370 --> 00:04:59,700 has a very unique email address, then you can search for the first part of the email on search engines 61 00:04:59,700 --> 00:05:06,600 so we can copy it and put it on Google, etc. as you can see. 62 00:05:07,590 --> 00:05:12,720 So in this lecture, you have learned how you can utilize search operators to find whether an email 63 00:05:12,720 --> 00:05:18,840 address is indexed by search engines or not, and how to search for the first part of an email address 64 00:05:18,840 --> 00:05:25,530 on Google or any other search engine to find if there are any accounts that uses the first part of the 65 00:05:25,530 --> 00:05:28,080 email as a username. 66 00:05:28,440 --> 00:05:33,540 Now you want to keep in mind that this is not going to work all the time, because if the person is 67 00:05:33,540 --> 00:05:39,030 not active online, then they will obviously have nothing on the internet that they have posted. 68 00:05:39,030 --> 00:05:44,850 So this sometimes works and sometimes doesn't work, but I think that it's always good to give it a 69 00:05:44,850 --> 00:05:50,220 try, because you might be able to find information that you will not be able to find otherwise.
