So, yes, this will be the start of the suckering section in this, we will we will be looking at the
trial of the circle.
So there is no exact definition for the circle, but circle can be defined as a code that keeps on the
team's mission and uses the river.
This circle is the code that is being executed on the mission.
And after discussion, we get the rules and the code need not be the reverse order.
It can be potential character.
But in order to get to in order to take advantage of the victim's machine, we generally like the reverser
circle.
If we have to use the metal plate, it will be probably known about how to create using a of venom.
You put the host airport and all those options and you will create the either by nature or nurture or
whatever circle you need.
So that's how you create using them.
So you just enter the command and you get the circle.
And the process of writing the circle is of course, as similar to process of writing, programming
or programming, the same process of writing the record as concertgoer.
Now there are some properties you need to know.
Silcott should be as aggressive as possible because the positions of the victim's machine might limit
the size of the buffer.
That means you can only press 400 or 500 words down, plus more than that.
So there will be some limitations when you are doing this type of role for us.
That's why we need to write as you need to circle as soon as possible.
Also, Circle should be free from bad characters.
Okay.
These are not any bad characters in nature, but these are the bad characters for us, for attackers.
Let's see the examples of bad characters.
That is zero zero which is Nabay zero zero is this is called Sudarshan.
That is a new line we have seen in our programming.
And this is the slasher, which is the character written.
So why are these bad characters so in applications, the process, the string that wins user input like
username and password, they're being format, right.
And then if you press zero zero, this number will act as Terminator.
That means if you pass 50 characters and then elevate and then 50 characters, first 50 characters were
taken to the buffer for an application on seeing this, another character, nabay the screen, the application
stops processing the taking.
That means it will take only the first 50 words and the string of traditional will get truncated or
will not be taken as an input by the application.
So in this case, after the break, our string is getting cut off that way, if we include this number
in our circle of obviously our circle will not get executed fully and we does not get any reversal.
So this number is almost.
You can't Arabic because even every application processes are strings and considers this as an Arabic.
And Giraldi will be used commonly in Web applications using Web servers in the servers when the request
or response is being processed, when the request is processed.
You said that slash GDP slash not one or 1.0 and then you give the special session.
So by putting this racialization that we will and treats as a single request and after this special
session, the input will not be considered into the application.
So that's why you need to avoid these two characters in November applications.
Also, you need to exclude these characters because this is right.
You know, so bad character and these two are bad characters for Web applications.
So these are the main properties you need to consider when coding their QAQA.
