Should be somewhere around here

The best of all was to keep changing your wireless pass regularly. If the device support encryption, choose
the higher one. If SSL Cert required, create one

Where you running these when you got hacked? WPA is weak and can be cracked easy but WPA2 is much harder to crack and if you use a pass phrase longer than 32 characters it is very hard.

WPA-AES is very strong. Especially if there are other networks in the area. If a hacker sees that he will probably go hunting for a different network... Use a password that is long, contatins upper and lower case letters, numbers and specials characters. Remember 73zqdujkkeswd92 is much more effective than soccer1234 b/c cracks will try words in the dictionary first.

Also, I don't think it's necessary to change your password because it's not like the hacker is going to get the password and then sit on it for 4 months before using it. As far as I know they can't slowly figure out what it is either, so IMO not neccessary. Spend the time to make a good long, comlex password and remember it rather than changing it everyday.

Hi Guys, Thanx for your help I was using WPA-PSK [TKIP] + WPA2-PSK [AES] when i got hacked my password was 10 characters long with upper and lower case with a special character I have made it a lot stronger now but I was wondering if there is any more i can do with the features with my Netgear Wnr2000 wireless-n router.

Don't use wireless. The problem with wireless is that you send every thing out into the air which can be intercepted and decrypted.

If you want to prevent the hacker from gaining access to your systems through the wireless you can use MAC filtering in addition. This will allow computers with specific MAC addresses to connect to your router only. You can get your computer MACs by doing an IPCONFIG /ALL.

All of this can be broken by known techniques that I can't mention that are available on the Internet.

Now getting down to the problem at hand. Catching a hacker is much like trying to catch a thief. Most hacks are done by someone you know and usually through physical contact with your computer. They install something called a Trojan which establishes a connection to their server on the Internet. Most firewalls are One Way which means they block attacks from the out side not from within. What the hacker will do is install a Keylogger on your computer which logs your key strokes and the Trojan will phone home with its logs.

The other way a Hacker can get a Trojan on your computer is through you. They either send you an email with an attachment or you download it through a Bit-torrent. I have seen trojans come from Key Generators that come with illegal copies of software like MS-Office that you down load from a bit-torrent like Lime Wire. When you run the app to generate a key that you can use to install Office it asks you to install the key generator which installs the Trojan. I can't tell you how many times I have cleaned up a computer that has been infested this way.

The best way to find this is by using NETSTAT /B which will tell which application/services have active connections to the internet and the address they are connecting to. Then you can use one of the WHO IS lookups on the internet to check each of the connections to know who they are. If it is Google then it is probably safe but if it it is a major ISP like Comcast then chances are it is the hacker unless you are with Comcast and you get your email or other services with them. You have to have a good under standing of the well known ports and what to look for to use this tool. Most often anti-viruses will do this for you but if you get a really good hacker then you will need to work at this level.

Personally, I don't do banking over WiFi. Have two computers or a docking station were you can hook into a hard line to do this. I prefer two computers because I use one for fun and one for business. This way if my fun computer gets corrupted it does not affect my business computer.

MAC filtering won't do a thing. In the process of decrypting packets to access the network, one of the first pieces of information gleaned is the MAC addresses of machines already communicating on the network. Once known, any MAC is trivial to spoof, and any attacker with enough information to access the network will already know at least one "allowed" MAC address.

Dude, if your using AES, that's pretty good. And to Ace_Omega: Hacking is not mostly done with physical contact from the computer. If you knew anything from a Security+ class, then you would know that Wireless hacking is easy. I do it to my network all the time (Mostly because I forget the Wireless Key.)
