Well, there is a useful tool called Trivial FTP (TFTP) which can be used by a attacker to hack firewalls.

How does it work?

While scanning UDP ports, you will want to pay close attention to systems with port 69 open. Cicso routers allow the use of TFTP in conjunction with network servers to read and write configuration files. The configuration files are updated whenever a router configuration is changed. If you can identify TFTP, there is a good chance that you can access the configuration file and download it.

Here are the basic steps:-

(1) Determine the router’s name. NSLookup or Ping –a can be useful.

c: \>ping -a 192.168.13.1

Pinging Router1 [192.168.13.1] with 32 bytes of data:

Reply from 192.168.13.1: bytes=32 time<10ms ttl="">
Reply from 192.168.13.1: bytes=32 time<10ms ttl="">
Reply from 192.168.13.1: bytes=32 time<10ms ttl="">
Reply from 192.168.13.1: bytes=32 time<10ms ttl="">
Ping statistics for 192.168.13.1:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 0ms, Maximum = 0ms, Average = 0ms
(2) After the router’s name is known, you can then use TFTP to download it from the TFTP server.
c:\>tftp -I 192.168.13.1 GET router1.cfg

Transfer successful: 250 bytes in 1 second, 250 bytes/s
(3) If you are lucky, you will be rewarded with the router’s configuration file.

Blocked web site, huh? Need a proxy?

1) The first and most common way of using google to bypass blocked sites is just to search for the site and then clicked the “cached” link that appears on google. Easy, simple, and frequently works for static information.

2) Passing the site through google translator works well as well. Here’s the URL to use:

Code:

http://www.google.com/translate?langpair=enen&u=www.blockedsite.com

(where blockedsite.com is the site that you wish to visit)

This translates the site from english to english and works because the ip address will appear as google instead of you. Here’s a link to tech-recipes passed through the translator as an example. You can actually do this with any langpair. Change enen in the URL above to spanish by using eses and it still works.

3) Unique method that I have not seen described before is to search through google mobile. Google mobile will “convert as you go” very similiar to the translation method above.

Just search for your site with google mobile and click on the link it provides. Here’s is tech-recipes brought up through google mobile search. Once again, this will allow you to bypass any blocks because the IP request comes from google not for you.

Like the translation method above, google will continue to “proxy” as you continue to visit links through the site. And ya it is also useful to retrive some information from net which is currently not available.
