1 00:00:00,440 --> 00:00:08,090 Another method to find someone's email address is by using collected usernames from social media profiles 2 00:00:08,090 --> 00:00:12,320 or online accounts to form an email address. 3 00:00:12,950 --> 00:00:14,960 So let me show you an example. 4 00:00:14,960 --> 00:00:19,640 Let's say that I have gathered this usernames about a person. 5 00:00:19,970 --> 00:00:28,370 So the person has used Siraj as his Facebook username and this one as his Instagram username, and this 6 00:00:28,370 --> 00:00:30,350 one as his LinkedIn username. 7 00:00:30,350 --> 00:00:35,210 So what I can do is form an email address with these usernames. 8 00:00:35,210 --> 00:00:43,250 For example, Siraj will become Siraj at gmail.com, at hotmail.com and at Outlook.com and apply the 9 00:00:43,250 --> 00:00:48,260 same with other usernames that you have collected from the target profile. 10 00:00:48,680 --> 00:00:56,180 And after we form a list of possible email addresses, the next step is to verify this list and see 11 00:00:56,180 --> 00:01:01,670 what email addresses are valid and what email addresses are not valid, and the email addresses that 12 00:01:01,670 --> 00:01:04,610 are not valid has to be excluded from this list. 13 00:01:05,360 --> 00:01:05,720 All right. 14 00:01:05,720 --> 00:01:07,940 So let's come back to our notes. 15 00:01:08,000 --> 00:01:10,970 Here are Rishi Kabra online accounts. 16 00:01:10,970 --> 00:01:17,180 We can see that he used Rishi Kabra, which I believe is an auto generated username on his LinkedIn 17 00:01:17,180 --> 00:01:18,020 account. 18 00:01:18,050 --> 00:01:27,140 And we have underscore RK 132 on his Twitter account and Rishi Kabra 132, RK 132 Rishi Kabra. 19 00:01:27,140 --> 00:01:29,600 And we also have Rishi Raj Cobra. 20 00:01:29,600 --> 00:01:37,160 So I'm going to open my notepad and add all of the unique usernames that he used like this. 21 00:01:37,160 --> 00:01:42,290 And then I'm going to complete or form an email address with these usernames. 22 00:01:42,290 --> 00:01:47,750 So the first one has to be excluded because an email address cannot start with an underscore. 23 00:01:47,750 --> 00:01:49,700 And let me show you an example. 24 00:01:49,700 --> 00:01:55,880 For example, if you want to create an outlook, then we can add an underscore and then say next. 25 00:01:55,880 --> 00:02:00,290 And you can see that you cannot use an underscore at the beginning of an email address. 26 00:02:00,290 --> 00:02:06,920 And if we go to Google and say create your own Gmail, we can see that we cannot use the underscore 27 00:02:06,920 --> 00:02:07,730 at all. 28 00:02:08,030 --> 00:02:10,310 So I'm going to exclude this username. 29 00:02:10,310 --> 00:02:13,010 And now we only have three usernames. 30 00:02:13,310 --> 00:02:20,150 So the next thing that I'm going to do is to go to a website called expert.com. 31 00:02:20,330 --> 00:02:25,460 And this will allow you to find someone's email and verified at the same time. 32 00:02:25,460 --> 00:02:33,500 For example, I can say Rishi Kabra 132 and then say gmail.com and then find email. 33 00:02:33,500 --> 00:02:40,700 And this will show me whether this email address is valid or not or whether it can receive emails or 34 00:02:40,700 --> 00:02:41,300 not. 35 00:02:41,510 --> 00:02:47,390 So let me say at hotmail.com and we can see that this is invalid. 36 00:02:47,390 --> 00:02:49,820 So I'm not going to put this in my list. 37 00:02:49,850 --> 00:02:54,200 Let me try yahoo.com and we can see that it's unknown. 38 00:02:54,410 --> 00:03:01,400 So for now let's add Rishi Kabra 132 at gmail.com to our list like this. 39 00:03:01,820 --> 00:03:04,460 And then I can try all other usernames. 40 00:03:04,460 --> 00:03:06,470 But I'm not going to do this right now. 41 00:03:06,500 --> 00:03:12,190 You have got the idea you need just to replace the username and add a domain name and see whether it's 42 00:03:12,190 --> 00:03:12,970 valid or not. 43 00:03:12,970 --> 00:03:16,000 And all the valid emails has to be added to a list. 44 00:03:16,000 --> 00:03:23,470 And once you add all the possible emails that are valid to your txt or to your list, the next step 45 00:03:23,470 --> 00:03:26,740 is to check what email address belongs to Rishi Kabra. 46 00:03:27,160 --> 00:03:33,430 So what I always like to do is just to go to Facebook and then click on forgot password and search for 47 00:03:33,430 --> 00:03:34,840 the person on Facebook. 48 00:03:34,840 --> 00:03:36,250 So I'm going to say Rishi Kabra. 49 00:03:36,250 --> 00:03:38,710 We already know that he has a Facebook account. 50 00:03:38,710 --> 00:03:45,400 And then after I find his account, I'm going to say this is my account and this will give me some information 51 00:03:45,400 --> 00:03:46,630 about his email address. 52 00:03:46,630 --> 00:03:52,360 We can see that it starts with R and ends with two and it's at gmail.com. 53 00:03:52,360 --> 00:03:57,910 So this will tell us that this is the only possible email that he might use. 54 00:03:57,910 --> 00:04:02,500 And this is the one that should actually belong to Rishi Kabra. 55 00:04:03,010 --> 00:04:12,040 Next I'm going to go to gmail.com and compose an email and then paste the email that I have got in here. 56 00:04:12,310 --> 00:04:17,770 And you can see sometimes it will show us some information about this account. 57 00:04:17,770 --> 00:04:25,150 And in this case it showed us the person's name, which is Rishi Kabra, and showed us his profile picture 58 00:04:25,150 --> 00:04:27,730 that he used on his Instagram account. 59 00:04:27,730 --> 00:04:30,670 So we know that this is his email address. 60 00:04:31,030 --> 00:04:38,380 Now if I have searched for Rishi Kabra at gmail.com, we can see that we have got a different profile 61 00:04:38,380 --> 00:04:42,280 picture and we have not got a full name. 62 00:04:42,280 --> 00:04:44,320 We have only got a profile picture. 63 00:04:44,320 --> 00:04:50,680 And this is another Rishi Kabra who lives in the United States that we have seen before when we are 64 00:04:50,680 --> 00:04:53,590 searching for Rishi Kabra on search engines. 65 00:04:54,130 --> 00:05:01,600 So in this lecture you have learned how you can utilize the found usernames about a person and form 66 00:05:01,600 --> 00:05:07,450 an email address list and then use this list to check what email address is valid or not, and then 67 00:05:07,450 --> 00:05:11,650 check what email address belongs to the person that you are looking for.
