Can my wireless network be hacked even with WPA2 encryption?

Hi,

I have a question about my wireless home network. I set it up so that it is using WPA2 encryption, a 10 digit numeric key, and security filtering by MAC address. I have not disabled SSID broadcasting.

What I want to know is easily can this setup be cracked? And if it's easy, what should I do to make it more secure so it's almost impossible to crack unless someone tries a brute force attack on the password?

Thanks!

Also note the following section in the article:

"Weakness in TKIP"

It talks about how the TKIP algorithm in WPA is vulnerable to a similar flaw found in WEP, albeit on a much smaller scale in terms of the size of packets that can be hacked and decrypted.

No, they cannot crack your wireless password.

WPA2 is very strong, also with your mac address filtering (if you set it up so only the mac addresses you choose can connect) will not let anyone connect to your wireless.

May I ask why you think someone might hack your wireless? I doubt anyone would spend so much time trying to get through your security.

Yes, WPA1/2 is vulnerable to dictionary attacks and here is how. There is software aircrack-ng among others that can capture the 4 way handshake.

Once a hacker has the 4 way handshake, they can do an offline brute force attack. If you choose to use WPA1/2 PSK, just make sure you use a password that has letters numbers and symbols. Something you wont find in a dictionary and you will be fine.
also, mac address filter is a low level security posture. 802.11 frames are not encrypted. Someone with an analyzer can see the layer 2 frames. One can simply see the mac and then spoof it to their wlan nic. In fact thats how I share my wifi account at the airports with my freinds. They spoof their macs to the registered mac i have with at&t and get on the airport wireless.
