00:00:00,950 --> 00:00:03,170
Hello and welcome back.

2
00:00:03,170 --> 00:00:15,490
Today I will show you how to crank the zero registration good using both the compiler and SCC for TV.

3
00:00:15,980 --> 00:00:18,370
So let's open now will we be the compiler

4
00:00:22,450 --> 00:00:26,490
and how he knew he they say program

5
00:00:35,220 --> 00:00:40,280
he will use the patch the one we have already removed the next screen

6
00:00:43,460 --> 00:00:56,220
and look at it from so now received as a text box and a piece here a key and click register me you this

7
00:00:56,220 --> 00:01:00,190
button will execute we'll call the handler.

8
00:01:00,270 --> 00:01:02,100
Come on likely.

9
00:01:02,100 --> 00:01:07,480
So really want to know what happens inside the code for.

10
00:01:07,490 --> 00:01:08,970
Come on one click.

11
00:01:08,970 --> 00:01:11,450
You can double click on this.

12
00:01:11,530 --> 00:01:16,650
You look at the disassemble view and now we have the address.

13
00:01:16,750 --> 00:01:20,740
We can use this address in say excessive for the.

14
00:01:22,240 --> 00:01:26,310
So that is open the creamy inside.

15
00:01:26,400 --> 00:01:28,630
Said before we give you used used to back vision

16
00:01:33,820 --> 00:01:38,530
and then now we go to our address in which he thought copy

17
00:01:41,340 --> 00:01:45,200
and in here we would never get to the address.

18
00:01:45,250 --> 00:01:53,860
Go to rightly first and then Sally go to expression and paste the address here.

19
00:01:54,350 --> 00:01:54,760
Thank you.

20
00:01:54,820 --> 00:01:56,370
OK.

21
00:01:56,680 --> 00:02:10,210
So now we can put breakpoint here and you can get and run so many run now into how a zero key time in

22
00:02:10,220 --> 00:02:14,880
anything is registered and if you hit our breakpoint.

23
00:02:15,020 --> 00:02:17,720
So now we can trace through my pricing into

24
00:02:21,190 --> 00:02:22,210
carbon pricing into

25
00:02:25,550 --> 00:02:26,350
and more.

26
00:02:26,410 --> 00:02:30,880
My main point which I said earlier is the presenter

27
00:02:35,230 --> 00:02:36,310
and see what happens

28
00:02:52,460 --> 00:02:55,360
yes after this message you got his call.

29
00:02:55,720 --> 00:02:57,360
We get the message.

30
00:02:57,560 --> 00:02:59,280
Saudi registration could

31
00:03:02,690 --> 00:03:11,500
Yes so now we know this is the message box and that message man this is

32
00:03:14,390 --> 00:03:18,460
iffy so we can see that this is a message box.

33
00:03:18,700 --> 00:03:21,280
We sure give us a message.

34
00:03:22,180 --> 00:03:31,210
So if we screw up here analyze the code before it we can see all the strings have been set up for viewing

35
00:03:31,210 --> 00:03:34,480
and my message and then we scrub further.

36
00:03:34,480 --> 00:03:34,820
All right.

37
00:03:34,890 --> 00:03:41,540
That is have his this program and running in an entity called register.

38
00:03:41,540 --> 00:03:42,380
Hang it up here.

39
00:03:43,020 --> 00:03:50,730
So now if you run this time you keep an eye open to see what happens.

40
00:03:51,010 --> 00:03:54,190
What what are you what distraction brought us to the banned message

41
00:04:02,620 --> 00:04:02,960
all right.

42
00:04:02,960 --> 00:04:05,030
You can see the strings being loaded.

43
00:04:05,120 --> 00:04:10,380
It's a string compact and yet it's a gem.

44
00:04:10,640 --> 00:04:18,570
And notice then jammies if he doesn't take the jump he's going to look do see that string.

45
00:04:18,740 --> 00:04:26,560
That means this is too important just to put a breakpoint so easy.

46
00:04:26,690 --> 00:04:28,320
Go ahead and run it.

47
00:04:29,960 --> 00:04:38,040
Now he is not going to injure me with press f he he's going to look a bit messy.

48
00:04:38,240 --> 00:04:39,970
Be running all the way.

49
00:04:39,990 --> 00:04:44,640
You see the best train coming from here right.

50
00:04:44,730 --> 00:04:49,140
So now we know that this is the important part.

51
00:04:50,520 --> 00:04:50,790
All right.

52
00:04:50,790 --> 00:04:52,560
So heavy.

53
00:04:52,770 --> 00:04:54,610
Look for that.

54
00:04:54,660 --> 00:04:56,260
The comparison is being made.

55
00:04:58,040 --> 00:05:03,440
And by foot up this a string compare string campaign.

56
00:05:03,720 --> 00:05:05,120
We shall see.

57
00:05:05,310 --> 00:05:10,750
He's comparing two strings and he's comparing this string and the string.

58
00:05:10,830 --> 00:05:16,110
So let's put a high every point here and see what strings have been contact.

59
00:05:16,760 --> 00:05:25,080
So they just run it click and just tell me and run to our big point.

60
00:05:25,880 --> 00:05:38,370
And this year he has loaded this tree which is our input and he's also is also pushing this to this

61
00:05:38,370 --> 00:05:38,580
day.

62
00:05:38,820 --> 00:05:45,840
So he's pushing the string and the string that a stick in order to in preparation for this function.

63
00:05:46,680 --> 00:05:54,280
So this function is comparing this string and the string so this string must be 0 0 registration could.

64
00:05:54,660 --> 00:06:02,710
And you can confirm then by looking here and this address for 0 1 DDC he's our a.

65
00:06:02,850 --> 00:06:12,560
In other ways to look a dumb so rightly go to following them for go to this address for zero on the

66
00:06:12,620 --> 00:06:14,920
D.C. and you can see down here

67
00:06:19,310 --> 00:06:28,750
indeed at this address we have how registration could be Approach 2 0 2 0.

68
00:06:28,850 --> 00:06:33,340
So there is no comparison string compare.

69
00:06:33,510 --> 00:06:35,520
So now we know the password.

70
00:06:35,580 --> 00:06:39,060
The 0 key is actually April 20.

71
00:06:39,090 --> 00:06:41,880
He can be running and key in our cell.

72
00:06:42,000 --> 00:06:43,990
So that's funny how

73
00:06:47,270 --> 00:06:55,430
King the key in the 0 a pro Dash 2 0 2 0 0 0.

74
00:06:55,420 --> 00:06:59,510
Just tell me you run.

75
00:06:59,810 --> 00:07:02,660
Hey we should get how successful.

76
00:07:02,740 --> 00:07:04,440
I think so.

77
00:07:04,440 --> 00:07:14,080
We have successfully cracked this software to find the 0 key so that's all for this lesson.

78
00:07:14,080 --> 00:07:15,010
Thank you for watching.
