1
00:00:00,080 --> 00:00:03,350
Cybercrime can be originated from two main sources.

2
00:00:03,380 --> 00:00:06,530
Insider attacks and external attacks.

3
00:00:06,740 --> 00:00:08,440
Insider attacks.

4
00:00:08,450 --> 00:00:14,720
This is the most dangerous cyber risk facing organizations today, as it can last for a long time without

5
00:00:14,720 --> 00:00:16,760
them knowing about it.

6
00:00:16,790 --> 00:00:22,970
Such attacks come when there is a breach of trust from employees or other people like former employees,

7
00:00:22,970 --> 00:00:29,060
third party contractors or business associates working within the Target organization who have legitimate

8
00:00:29,060 --> 00:00:35,930
access to its computing systems and or information about its cybersecurity practices and defenses.

9
00:00:36,470 --> 00:00:39,500
Economic espionage falls under this category.

10
00:00:40,280 --> 00:00:41,710
External attacks.

11
00:00:41,720 --> 00:00:48,050
This kind of attack originates from outside the Target organization, usually coming from skilled hackers.

12
00:00:48,080 --> 00:00:52,980
Such attacks constitute the largest attacks against organizations around the world.

13
00:00:53,000 --> 00:00:58,910
A black hat hacker can try to penetrate the target organization's computing networks from another country

14
00:00:58,910 --> 00:01:01,370
to gain unauthorized access.

15
00:01:01,400 --> 00:01:08,090
Sometimes external attackers gain intelligence from an insider disgruntled employee in the target company

16
00:01:08,090 --> 00:01:12,840
who has information about its security systems to facilitate their illegal access.

17
00:01:12,860 --> 00:01:15,470
How are computers used in cybercrimes?

18
00:01:15,950 --> 00:01:21,890
Cybercrime can be divided into three main categories with regard to how the computing device was used

19
00:01:21,890 --> 00:01:23,060
to commit a crime.

20
00:01:23,690 --> 00:01:24,620
One.

21
00:01:24,770 --> 00:01:28,250
A computing device is used as a weapon to commit a crime.

22
00:01:28,640 --> 00:01:38,060
Example launching denial of service DDoS attacks or sending ransomware to a computing device is the

23
00:01:38,060 --> 00:01:39,510
target of a crime.

24
00:01:39,560 --> 00:01:44,330
Example gaining unauthorized access to a target computer.

25
00:01:44,600 --> 00:01:45,560
Three.

26
00:01:46,010 --> 00:01:49,650
A computing device is used as a facilitator of a crime.

27
00:01:49,670 --> 00:01:57,050
Example using a computer to store incriminating data or to make online communications with other criminals.
