How To Intrude the Wireless Intruders?

[hanief84]

Hi! I'm wondering whether is this possible or not? Let say if I have my own wireless network. A few intruders got in the network. Now, is it possible for me to go inside their PC's or laptops thru the wireless network?

A lot of people said to me that I just need the Firewall and the WEP or WPA encryption plus becarefull with the way I type the SSID in order to secure my wireless network.

wep or wpa encryption works ok. personally I leave it off because it slows the network because it has to encrypt then decrypt all information. I turn my ssid transmitter off and then I turn on mac address filtering and dhcp limitations. My network will only assign 3 ip addresses other than the router which is how many computers I have. Then the mac address from those computers has to be entered into the router before you can connect. And this is assuming that anyone will find my network without ssid. I just enter all the setting manually and it works fine.

It might be possible to gain access to their computers depending on how clueful or less they are...


personally I think you shouldn't worry about that and should worry about properly securing your AP.


I strongly disagree w/ everything just about the last guy said.

ecryption does come with some overhead weeeeell worth it IMHO.


Ideally you will have WPA2 available on your wifi router/ interface cards... followed in order of security desirability /strenght..WPA , WEP

turn on the best one available to you...don't worry about it slowing anything down.


turning off the SSID is a joke from a security standpoint it is trivial to locate the network w/ SSID turned off..... infact I turn mine on... tooo mark my territory (yes like a cat ... i.e. advise any neighbors w/ shinny new wifi routers to stay the hell off of my channel).

mac filtering is almost as much of a joke as turning SSID off...it is relatively trivial to spoof a mac address/ capture an allowed mac from the network.

DHCP client limits.... hmmmm... good thing nobody will ever think to manually enter a IP address in range.... which they will know from their recon finding your SSID / and MAC address.


now turn on WPA2 or WPA... or if you have no other option WEP

change your default SSID and ADMIN passwords for the router // disable remote admin.

If they have a software firewall it would be more difficult.

For the Linux Savy... :twisted:

I forgot about that... that would be funny.
