All language subtitles for 011 Grabbing Banner-subtitle-en

Another user for netcat it's to grab Zyban.

And what I mean by grabbing Ziman banner whenever we try to connect to an open port on another machine

that has a service it will display some information about the service and this can be very helpful for

any hacker to identify as a product or the software that is running on this machine and try to find

a vulnerability.

Let me give you a small example assumes that I scanned the Windows machine from my colonics machine

and I notice that they have put into an open will talk about scanning later on.

But the point is that they have this piece of information and I know that 4:21 usually is used for FTB

so I need to know what product that or what service or software they are using.

So I can start searching for any weakness or vulnerability so I can typeset and see netcat and then

the windows IP which is one that was 0 9 and then support 29 21.

So I'm asking him to connect to this specific computer's report into and that I know that it's open

and 1c I don't have I don't need to have a username and password because what happened is whenever I

try to connect to the port a banner will be showing it's sending you welcome to ability server two point

three two point two.

So just by doing that I know knows that the Windows machine has this server with this version so I can

start search for any vulnerability related to such service.

Well if I didn't do it I know that he got FTB server running except I don't know what product he's using

or which version he's using.

So this is called a banner grabbing.

It's not requesting or it doesn't need any username and password.

You just try to connect using netcat and from the burner you can get some useful information as you

so.
