Hacking Router and Switch

the hacking technique that i will tell to you is very old technique , what we will do is very depend of your luck. :D but we also have some literatur to make you success percentage become higher. what you only need to know is the type and the brand of the Switch and Router. if you don’t know it you still have a chance to get “in” but it not easy of course.the first technique i tell(you know the type and brand the target) you is depend of your luck because it will brute force.but the second is depend of your skill fo “social enginering”. this technique is not common hacking technique it not need any tools. its just use your head. your intellegence will tested here because you need to guess the passowrd and the username with only chat and asking random question to the network administrator. you now , yesterday i read some one post that tell that we can hack yahoo! or hotmail email just use this technique. of course we can , but it very difficult to guess the password since we may only have to pick one password from everthing you can think!!.First how can we hack a switch just use one tools . and this tools is very common tools.we will use port scanner. and this is the step :

* Scan your Local Network using some tools you can use Angry IP Scanner like i do. and you only need Scanning for OPEN port 23.this port is usually use for switch
* after getting the IP you can try the telnet connection to that IP. telnet [IP target] 23

and now your intellegence will tested. of course we don’t know the username and password for that switch. but i bet the username “administrator” or “admin” that standart username for network engine like that will work. you can use one of that username and now all depend of your luck. to higher our chance to get pass you can read the default password list for all type.but i dont have the list of default password for switch so you need to use “social enginering” technique. good luck :D just incase try to keep the password (empthy) maybe it will work.because it works for me.. :D

and now for Router. luckly i have the list of default pasword for Router. and it hundreds !! and over. you can chose one of this. or you can read here router-default-password. that al l happy hacking..
