1
00:00:00,170 --> 00:00:06,830
So this we don't want to cover the important topical instruction pointer, so this is a register.

2
00:00:07,260 --> 00:00:15,240
We are seeing registers like Yaqubi and this inflection point is also a registered independent by Epee

3
00:00:15,240 --> 00:00:18,550
Interpretively Systems IAP extended U.S. pointer.

4
00:00:18,870 --> 00:00:26,800
So what does digital content these this register address to the next injunction to be executed?

5
00:00:27,690 --> 00:00:34,440
So if my program is executing the first instruction, the second instruction will will be stored in

6
00:00:34,440 --> 00:00:35,470
the instruction pointer.

7
00:00:35,760 --> 00:00:39,450
So that program flows to that address.

8
00:00:40,900 --> 00:00:47,010
And this is the one of the best tool for hackers, because if we can control this, we can control the

9
00:00:47,010 --> 00:00:47,430
program.

10
00:00:47,700 --> 00:00:48,050
Right.

11
00:00:48,420 --> 00:01:00,150
And this instruction, wonder how some like mitigations, like some protections, like we cannot use

12
00:01:00,150 --> 00:01:05,420
this instruction, like modifying with more operations.

13
00:01:05,730 --> 00:01:15,180
So if I said more value than that injunction will not get executed because we cannot perform any operations

14
00:01:15,180 --> 00:01:16,310
on the instruction point.

15
00:01:17,250 --> 00:01:19,770
It's like read-only format.

16
00:01:20,610 --> 00:01:28,650
And that's why in basic Tacho for us, we will all for the application with our data and we exactly

17
00:01:28,650 --> 00:01:30,570
find the offset of injection points.

18
00:01:30,870 --> 00:01:31,470
And we.

19
00:01:31,470 --> 00:01:32,040
All right.

20
00:01:32,040 --> 00:01:39,230
Now our data with the PSP or some other instruction which points to a circle.

21
00:01:39,990 --> 00:01:46,410
So that's why we cannot change the injection point with some just adding section subtraction, injection

22
00:01:46,410 --> 00:01:47,420
or more instruction.

23
00:01:48,030 --> 00:01:49,800
We need to modify.

24
00:01:50,220 --> 00:01:52,820
We can modify if there is an order for something like that.

25
00:01:53,550 --> 00:01:58,050
And this is one of the most important registers.

26
00:01:58,800 --> 00:02:03,590
Just don't forget, we'll also be looking at this instruction pointer in the debate.

27
00:02:03,600 --> 00:02:06,960
We will get in the debugging section.
