0
1
00:00:08,340 --> 00:00:10,950
So next we're going to install objection.
1

2
00:00:11,070 --> 00:00:14,130
This tool will be used for dynamic analysis.
2

3
00:00:14,130 --> 00:00:21,580
So just google objection Android and the first result you find is objection.OK.
3

4
00:00:21,620 --> 00:00:23,390
Some basic information.
4

5
00:00:23,630 --> 00:00:26,900
It's a runtime mobile exploration tool kit.
5

6
00:00:26,900 --> 00:00:28,890
It's an extremely useful tool.
6

7
00:00:29,150 --> 00:00:33,300
But if you go to the installation page have a look at the prerequisites.
7

8
00:00:33,350 --> 00:00:40,860
So for example Python you have to have python version three point four or greater Pip 3 has to be version
8

9
00:00:40,860 --> 00:00:43,050
nine point 0 or greater.
9

10
00:00:43,050 --> 00:00:46,000
So make sure you have these installed.
10

11
00:00:46,040 --> 00:00:50,390
Another thing you should make sure you have zipalign installed.
11

12
00:00:50,510 --> 00:00:53,720
Otherwise you might receive some errors during installation.
12

13
00:00:53,720 --> 00:00:59,220
So let's just run sudo APT install zipalign.
13

14
00:00:59,420 --> 00:01:02,400
Here it is already installed now.
14

15
00:01:02,400 --> 00:01:05,490
Objection uses apktool in the background.
15

16
00:01:05,670 --> 00:01:14,090
If you remember before we installed apktool using APT get let's actually remove apk tool and
16

17
00:01:14,090 --> 00:01:22,810
install the latest version so sudo Apt get remove apktool.
17

18
00:01:22,960 --> 00:01:28,380
The one we installed was actually an older version and you may receive errors when running objection.
18

19
00:01:28,840 --> 00:01:36,370
Anyway this is a good exercise to show you how to upgrade apktool if needed so just google apk
19

20
00:01:36,390 --> 00:01:40,380
tool installation go to their page.
20

21
00:01:40,380 --> 00:01:44,140
There are different versions for Windows Linux and Mac OS.
21

22
00:01:44,370 --> 00:01:46,090
Follow their instructions.
22

23
00:01:46,350 --> 00:01:49,230
So first step is to download the script.
23

24
00:01:49,230 --> 00:01:51,490
Save this as a tool.
24

25
00:01:51,600 --> 00:01:54,950
Then download the APKtool .jar.
25

26
00:01:55,350 --> 00:01:57,630
Just find the latest version from here.
26

27
00:01:59,040 --> 00:02:01,350
One thing we need to do is rename that.
27

28
00:02:01,620 --> 00:02:04,750
So we just name it apktool without any version 
28

29
00:02:04,740 --> 00:02:05,980
number.
29

30
00:02:06,060 --> 00:02:06,430
OK.
30

31
00:02:06,430 --> 00:02:08,140
Saved.
31

32
00:02:08,340 --> 00:02:10,860
Give it some time to download.
32

33
00:02:10,970 --> 00:02:15,740
OK so now we have apktool downloaded.
33

34
00:02:15,740 --> 00:02:18,230
We need to make them executable.
34

35
00:02:18,230 --> 00:02:32,370
"chmod +x APKtool", " chmod +x APKtool.jar" now just move these files to user slash local
35

36
00:02:32,370 --> 00:02:37,520
slash been let's just go to user local bin.
36

37
00:02:37,720 --> 00:02:45,630
We will see our apktool files so that's where we can run our apktool from now you can add this to
37

38
00:02:45,630 --> 00:02:48,720
your environment variables. OK.
38

39
00:02:48,780 --> 00:02:54,250
Apktool is installed another tool you will need is jarsigner.
39

40
00:02:54,620 --> 00:03:01,100
So make sure you have JDK installed in your system and also make sure that there's an environment variable
40

41
00:03:01,100 --> 00:03:02,020
pointing towards it.
41

42
00:03:03,000 --> 00:03:09,990
In our case it's downloaded in users slash locals and if we go in this folder we can see jarsigner
42

43
00:03:10,110 --> 00:03:16,610
is available to see if you have jarsigner or just type jarsigner.
43

44
00:03:16,610 --> 00:03:20,940
OK now with all these tools installed you should be able to install and run.
44

45
00:03:20,950 --> 00:03:22,350
Objection.
45

46
00:03:22,390 --> 00:03:27,430
We thought we would show you a few prerequisites that can cause errors if they are not properly configured
46

47
00:03:29,250 --> 00:03:35,260
and finally you can install by using Pip 3 install -u.
47

48
00:03:35,310 --> 00:03:39,660
Objection.
48

49
00:03:39,740 --> 00:03:43,960
It is important to have all the environment variables set.
49

50
00:03:44,150 --> 00:03:51,020
Make sure to have the following tools configured in your system with the path directories configured
50

51
00:03:51,080 --> 00:03:53,130
according to your application paths.
