1
00:00:00,440 --> 00:00:02,660
Now let's talk about Osint.

2
00:00:02,690 --> 00:00:05,900
What is Osint or Open source intelligence?

3
00:00:06,170 --> 00:00:14,270
Osint is basically using publicly available sources to collect information about an individual or an

4
00:00:14,270 --> 00:00:15,350
organization.

5
00:00:15,470 --> 00:00:24,200
And these publicly available sources could be books, newspaper, magazines, TV, radio, or the internet.

6
00:00:24,980 --> 00:00:33,440
Now, Osint is mostly used by journalists to uncover information or verify facts, etc., and it's also

7
00:00:33,440 --> 00:00:39,830
used by Ethical Hacker to identify and mitigate cyber threats and gather information about potential

8
00:00:39,830 --> 00:00:40,790
vulnerabilities.

9
00:00:40,790 --> 00:00:47,870
And it's used by law enforcement or police to gather information on potential threats and criminal activities,

10
00:00:47,870 --> 00:00:54,710
and is also used by businesses for competitive intelligence market trends and to monitor their brand

11
00:00:54,710 --> 00:00:55,730
reputation.

12
00:00:56,870 --> 00:01:03,350
Osint is not only used by these people, it's also used by recruiters, private investigators, and

13
00:01:03,350 --> 00:01:04,070
more.

14
00:01:04,700 --> 00:01:08,810
Now, there are multiple reasons why people use Osint.

15
00:01:08,810 --> 00:01:16,560
For example, employers use Osint to find information about job applicants and police or law enforcement,

16
00:01:16,560 --> 00:01:23,970
or a family member might try and use Osint to find a missing person or a missing family member.

17
00:01:24,570 --> 00:01:30,390
It's also used to conduct criminal investigations, and it's also used by ethical hackers to gather

18
00:01:30,390 --> 00:01:33,120
information on their pentesting target.

19
00:01:34,170 --> 00:01:41,940
Now, Osint is a skill, and the only way to learn Osint is by practicing gathering information about

20
00:01:41,940 --> 00:01:42,750
people.

21
00:01:42,750 --> 00:01:49,860
And when you go through this course, I highly recommend that you gather information about yourself

22
00:01:49,860 --> 00:01:54,570
first and then see what information you can find about yourself.

23
00:01:54,570 --> 00:02:00,450
This is the first thing that I've done when I've learned Osint, and I was able to find many information

24
00:02:00,450 --> 00:02:02,670
that are not supposed to be online.

25
00:02:03,510 --> 00:02:08,430
So when you go through this course, I highly recommend that you apply everything that you have learned

26
00:02:08,460 --> 00:02:10,980
just so that you can get experience.

27
00:02:10,980 --> 00:02:16,950
And the more you use Osint, the better it is to sharpen your Osint skills.

28
00:02:18,360 --> 00:02:23,930
In addition to that, when you are conducting an Osint investigation or you are trying to find someone's

29
00:02:23,930 --> 00:02:29,120
information on the internet, then you might be able to find surprising information.

30
00:02:29,570 --> 00:02:36,020
For example, you might be able to find their home address, passwords, Social security numbers, and

31
00:02:36,020 --> 00:02:36,680
more.

32
00:02:37,490 --> 00:02:42,530
And you might start questioning whether finding this information is legal or not.

33
00:02:43,400 --> 00:02:51,140
Since these information are online and are publicly available to everyone, then gathering these information

34
00:02:51,140 --> 00:02:52,970
is completely legal.

35
00:02:53,000 --> 00:03:00,320
As long as you don't use passwords that you might find online to access their online accounts because

36
00:03:00,320 --> 00:03:03,920
you are not authorized to gain access to their accounts.

37
00:03:05,030 --> 00:03:11,120
Now, the type of information that you can find about a person or an organization is very different

38
00:03:11,120 --> 00:03:17,870
from a person to a person, or from an organization to an organization, because this all depends on

39
00:03:17,900 --> 00:03:19,460
their online activity.

40
00:03:19,490 --> 00:03:25,100
The more active a person is, the more information you'll be able to find about a person.

41
00:03:25,130 --> 00:03:31,820
So you might be able to find emails, phone numbers, home addresses, date of birth, passwords, person's

42
00:03:31,820 --> 00:03:34,160
interests, and much more.
