1
00:00:00,320 --> 00:00:05,900
In a previous section, I showed you how you can gather information about a username by using What's

2
00:00:05,900 --> 00:00:07,940
My Name and Blackbird.

3
00:00:08,150 --> 00:00:14,900
Now there is a tool called Sherlock that you can install it on your Linux machine that will check whether

4
00:00:14,930 --> 00:00:19,100
a username has been used on hundreds of websites.

5
00:00:19,430 --> 00:00:25,670
Now some search results are false positive, which means that you might get a link, but once you open

6
00:00:25,670 --> 00:00:27,530
it you will not find any account.

7
00:00:28,010 --> 00:00:30,200
And installing this tool is very simple.

8
00:00:30,200 --> 00:00:34,910
All you have to do is to type apt install and then Sherlock.

9
00:00:35,990 --> 00:00:42,080
So you want to go to your Trace Labs Linux machine, and then you want to open the terminal as root

10
00:00:42,080 --> 00:00:44,150
by clicking on this icon.

11
00:00:44,540 --> 00:00:47,990
And then I'm going to type Osint as my password.

12
00:00:47,990 --> 00:00:55,790
And before I install any tool I always have to run the command apt update to update Kali Linux repositories.

13
00:00:57,140 --> 00:01:03,590
And after this I'm going to install the tool by typing apt install and then Sherlock, and then hit

14
00:01:03,590 --> 00:01:04,400
enter.

15
00:01:04,460 --> 00:01:07,040
And now the tool has been installed.

16
00:01:07,550 --> 00:01:14,660
And then I'm going to move to my desktop by typing CD home, Osint desktop like this.

17
00:01:15,080 --> 00:01:21,410
And now I'm in desktop, and now I'm going to run the tool by typing Sherlock, and then the username

18
00:01:21,410 --> 00:01:28,190
that I would like to search for, for example Rishi Kabra 132I can add additional username, for example

19
00:01:28,190 --> 00:01:30,770
underscore rk 132.

20
00:01:30,770 --> 00:01:36,800
And I would like to print only found results by typing print found.

21
00:01:36,830 --> 00:01:38,660
And then I'm going to hit enter.

22
00:01:38,660 --> 00:01:43,100
And now it's going to search for this username across hundreds of websites.

23
00:01:43,100 --> 00:01:47,780
And once the search is done a txt file will be generated on my desktop.

24
00:01:49,250 --> 00:01:55,400
So here are the accounts that has been found for Rishi Kabra 132 we can see that we have a.

25
00:01:55,400 --> 00:01:57,110
TXT file on our desktop.

26
00:01:57,110 --> 00:02:00,870
We can open it and see all the found accounts.

27
00:02:00,960 --> 00:02:07,080
Now I already know that Rishi Cobra has a Hackerrank account, a Gravatar account and a GitHub account.

28
00:02:07,080 --> 00:02:12,870
But Rishi Cobra does not have an account on this website or on this website.

29
00:02:12,870 --> 00:02:16,980
And this is why I told you that some search results are false positives.

30
00:02:16,980 --> 00:02:23,970
So if I copied the first link and visit it, I can see that there is no search results.

31
00:02:23,970 --> 00:02:26,430
So I can't see Rishi Cobra account.

32
00:02:27,420 --> 00:02:29,400
So I'm going to close this file.

33
00:02:30,120 --> 00:02:34,530
And now it's checking to see if this username has been registered on any website.

34
00:02:34,530 --> 00:02:41,460
And this is why I always recommend using more than one tool, because as you can see, it wasn't able

35
00:02:41,460 --> 00:02:43,320
to find Rishi Cobra Twitter account.

36
00:02:43,320 --> 00:02:47,040
It only found accounts that Rishi Cobra does not have.

37
00:02:47,370 --> 00:02:49,260
And here is the second txt file.

38
00:02:49,260 --> 00:02:53,010
You can obviously upload these txt files to your usernames.

39
00:02:53,010 --> 00:02:58,950
Note that we have created before, just so that you can have all the information in one place.
