1
00:00:02,170 --> 00:00:07,750
In the past getting information was complicated time consuming and expensive.

2
00:00:09,710 --> 00:00:16,830
Today all sorts of information is available about almost anybody and accessing it doesn't require money.

3
00:00:17,940 --> 00:00:24,780
All it takes is to create an account on any given social networking site AMANOR Internet only friends

4
00:00:24,790 --> 00:00:27,970
there could be people who only pretend to be normal users

5
00:00:33,220 --> 00:00:36,160
creating a false identity is really easy in the Internet.

6
00:00:39,330 --> 00:00:40,870
Why would anyone want to do it.

7
00:00:43,280 --> 00:00:45,560
To gain our trust and to get to know us better.

8
00:00:46,880 --> 00:00:53,090
Which makes an attack on our computer system stand a better chance of succeeding.

9
00:00:53,100 --> 00:00:55,700
I'm talking about a socio technical attack here.

10
00:00:58,460 --> 00:01:02,030
Let's see the amount of information that you can find yourself on the web.

11
00:01:05,920 --> 00:01:16,440
To do this other than look at public Web sites and services attackers also use specialized tools that

12
00:01:16,440 --> 00:01:22,200
demand for information is so huge that there are special paid information research services dedicated

13
00:01:22,200 --> 00:01:25,240
to finding information.

14
00:01:25,240 --> 00:01:31,840
Let's start with a site called Iken stuck you in the slide you can see how the service looked when it

15
00:01:31,840 --> 00:01:32,700
was active.

16
00:01:34,040 --> 00:01:39,210
It was shut down after a year we'll visited later and we'll see why it was closed.

17
00:01:42,880 --> 00:01:47,950
The site was geared towards raising awareness that posting a picture on social media pages revealed

18
00:01:47,950 --> 00:01:53,670
not only the image itself but also disclosed information on when and where it was taken.

19
00:01:56,010 --> 00:02:00,960
All current smartphones and many professional cameras automatically add geolocation data to pictures

20
00:02:04,830 --> 00:02:09,720
and their applications and tools on the Internet that let you view the information embedded in images.

21
00:02:11,690 --> 00:02:16,520
I can stalk you tracked the information from pictures published on social media pages for a year.

22
00:02:19,050 --> 00:02:25,530
As you can see tons of confidential information on people was disclosed every minute.

23
00:02:25,550 --> 00:02:29,930
This is a relatively harmless feature in some cases but can be really risky and others

24
00:02:33,080 --> 00:02:34,040
as it turns out.

25
00:02:34,070 --> 00:02:36,680
This poses a great risk for some groups of people

26
00:02:39,930 --> 00:02:43,510
American soldiers who were stationed in Iraq for example.

27
00:02:43,530 --> 00:02:51,190
Take pictures of themselves standing next to a new chopper and uploaded to a social networking service.

28
00:02:51,210 --> 00:02:55,890
The pictures were seen by terrorists who would use the embedded coordinates to identify the location

29
00:02:55,890 --> 00:02:58,460
of the base and where the choppers flew.

30
00:03:00,030 --> 00:03:02,460
This ended in the destruction of four choppers.

31
00:03:05,790 --> 00:03:09,410
This is why you need to think before you post personal information on the Web.

32
00:03:11,460 --> 00:03:13,720
We'll come back to I can talk you in a moment.
