Hello and welcome to a new section in this section we are going to look at in line patching again,

2
00:00:08,700 --> 00:00:15,570
this technique is about how to create your own house without using any external libraries offering.

3
00:00:20,490 --> 00:00:24,120
How does it work in this diagram here on the left?

4
00:00:24,360 --> 00:00:26,880
He's our -- program.

5
00:00:27,400 --> 00:00:29,310
And on the right, he's the target.

6
00:00:30,910 --> 00:00:37,510
So the target in sight there is a function call, regional function, which we are going to hook.

7
00:00:40,170 --> 00:00:45,450
So the first step is we need to somehow attach the hook to the target.

8
00:00:48,110 --> 00:00:53,690
The hukou within safety or region address of this target function.

9
00:00:54,650 --> 00:01:02,030
The reason he does that is because so that he can optionally revert revert the original function back

10
00:01:02,030 --> 00:01:04,130
to its original state if he needs to.

11
00:01:06,390 --> 00:01:10,140
He also suggested price of the original function for the same reason.

12
00:01:11,940 --> 00:01:18,060
And then he will pitch in memory to replace this original function figure address.

13
00:01:18,200 --> 00:01:20,130
Oh, our modified function.

14
00:01:22,000 --> 00:01:29,200
So this is our money, if I can call my function now, then once the target executes and calls this

15
00:01:29,320 --> 00:01:38,080
function, you execute our modified function instead of the original function, and optionally we can

16
00:01:38,530 --> 00:01:47,560
revert the function back by copying back the address of the original function because we have already

17
00:01:47,560 --> 00:01:50,710
safe the address here as well as the instruction, right?

18
00:01:51,790 --> 00:01:56,650
So this is the simple, high level view explanation of how to do in line.

19
00:01:58,930 --> 00:01:59,860
So that's all for.

20
00:02:00,040 --> 00:02:03,150
VIDEO Next VIDEO We'll take a look at the code.

21
00:02:03,730 --> 00:02:04,960
Thank you for watching.
