i don't have a clue......

-=Me and my silly question=-


i got a question what kind of metod is used to penetrate a firewall, how hackers do that ... i try to do something like it.. of course! I own the computers where I was trying... anyway ... I try to ping the computer no responce.... I try telnet... no luck.... I try finger.... no luck.....I try ftp conection... no luck..... I wondering how they can do it? .... how they stablesh a conecction.... the firewall refuced all the atemps to conection and close the open ports.... So what is the trick?........


.......................... Thank you...............................

Well it sounds to me like the computer you are trying to get into is well protected. It doesnt respond to pings, it doesnt run telnet, finger, or ftp, it doesnt run any services, and the firewall closed off all open ports. I think this is the kind of machine that is extremely difficult to break into. The trick is to find a computer that is running vulnerabe services. Theoretically it is possible to get into this machine, but it might not be very likely.

Are there any open ports on this computer at all?
If there aren't any (which I doubt) it is almost impossible to hack this guy - the only way is to know what is the exact type of firewall he is using and search for vulnerabilites over the NET.
And if you don't know what is the guy's firewall - I guess you are stuck although you could try some floods or DOS attacks.
P.S. Don't try :)

seems like a good firewall but why r u trying 2 penetrate it in the first place?

prodikal> Claimes he is doing pen testing on his own system.

elfc> If what you say is true, then the firewall probably can't be hacked. Although it can still be DoS'ed. Do me a favor on your next post though. Get rid of all the stupid red and blue and large fonts. It makes it VERY hard to take anything you say seriously. Thanks.

or, if you know the fire wall you can possibly find a way to make it crash, depending on which kind it is.

1. to ...........ThePreacher........... thank you for the tip!


2. to ...........sw2v......................yes I run a scanport on the computer and yes I found some
open ports ... but when I try a raw conection do not work..
................thank you...................

3. to ............prodikal.................yes I guess it's a good firewall and.. yes I try to penetrate
I wondering how they stablesh a connection to break in?
...............thank you...................

4. to............souleman.............. yes probably the firewall can't be hacked....and I get rid of
the font type.... and about dos'ed I DON'T TRY TO CRASH THE
SYSTEM..I just wonder how they get the conection........
...............thank you....................

5. to.......lord_darkside_x.........thanks you for the tip!

thanks to every 1 For the tips and coments...

Well, I guess I'm in a good mood.

Most firewalls arn't really gone thru persay. Most times a firewall protects a companies internal network. Now the reason you won't get thru is because your ip is not one of the recognized and trusted ip's. So, what is usually done is most companies run an e-mail system, a web service, or both. Now an e-mail system is obviously going to be outside the firewall so it can get the e-mails. Now most likely that e-mail server is also trusted by the firewall. SO, what you will want to do is gain root access on the e-mail/web server, and then use that server to telnet to a server behind the firewall. Thru this the firewall will not recognize your ip as the one trying to connect. It will recognize the e-mail/web servers ip and most likely this ip is one of the trusted ip's. So, there ya go. This method is usually called leapfrogging. Happy hunting.

Also, you can get some stuff thru a firewall by pinging with a different set of tcp packets. You can search more about this by searching for "firewalk" on google.


Note: These methods do not work on all firewalls.

thank you for the infomation!
this explain a lot to me..

of course if all else fails you can do a little investigating, find out some names of people who use the network, determine the networks naming convention for email and send an attached trojan to tunnel threw the firewall to a few of them

I kwnow the ip's, the network type, but I can not conect to the computer bacause .....Firewall ...... A trojan I don't think it work because they are runing
Mcaffe Anti-virus, I know that for fact, and some e-mail services scan the mail for virus.


........................... thanks for the coment!..........

Ok. You own the PC's. That's good. If you want to play games, its always best to do it on your own PC..

They are running??? I thought they were your PC's...

My distrust aside... Running AV software is all well and good.. but is it up to date? I'm assuming this is a home user, and a lot of them forget that updating is required, so while they have their trusty AV software installed, its only looking for virus's from before 2000..

How can you find this out? well, you said you already know that they are running the AV suite... I'm sure finding out what virus defs they have going wouldn't be too hard...

On a large scale, with a company email system, one way to find out is to send them a few new email virus's... A lot of the corporate AV's which can scan email also notify a sender as well as the recipient when their email gets quarantined....

I also picked that "my computers" -- "they are running". But I'm sure elfc must have a good explanation for this one?-)
I really wonder this thread, this must be the first "how do I hack" one that people have answered without any flames!! Anyway, I think I'll also do some searches about some of those things people mentioned.

They are running ......

The machines They are runnig.... and I know THEY ip's, and THEY NAMES... any way.. if you want get me flamed.. go ahead. I don't care ...... I not doing nothing illegal, I just try to get some answers to my questions ....


how do I hack?------------ I never ask that....!

My question was about "FIREWALLS" .... and this is a Security Related discussion forum ,,,

or not?

----- Flame..... don't Just say it-----
----Do iT--------


and thanks For the Coment............

....y do u ask ?

use nmap to find open ports, and then use nessus to scan for vulnerabilities

lol sounds fishy to me... anyway I guess "they" don't really mind having you scan them...
If you bugged me as much as you are bugging "they" I would have contacted your ISP long ago so I guess "they" are either dumbasses or they don't mind you trying to get in :D
Remember firewalls usually log attack attempts and that if "they" stop being dumbasses (by some miracle), "they" can get you in trouble if you didn't get their consent ;)

thanks every 1 for the coments.....and Info.

There are firewalls that block out pings and stuff. They exploit the system and find a vulnerability and figure a way to get past it.

Hmm, maybe they should learn spelling in "chicagoland"... You meant that the machines in your network are running McAfee's and you know their IP's and names.

Hey, no offence man, cool down. Basically you asked "how to hack" and there is (or now used to be?) tendency to flame those posts here in AntiOnline. The fact that there now were no flames really surprised me. I can see you're not trying to hack anyone but some people do not read the full post or do not understand it and then flame the one who posted. Peace.
