Wireless networks are really common these days. It even common the unsecured
wireless networks. May be the wireless users are lazy or not much aware about
wireless security, which hackers found easier and free way to use those
unsecured wireless networks around them to get free internet for themselves.
The basic thing of vulnerability related to wireless networks are the method it use to encrypt the hack wifi password. There are few different types of encryption in wifi networks.
WEP: Wired Equivalent Privacy
It is breakable even if it has configured correctly
Can be broken in within like 3 minutes or so
WPA or WPA2: Wi-Fi Protected Access
This encryption type is reated to provide stronger security
But it is still able to be cracked if they are using a short password.
If a user is using a long passphrase or password, these protocol are uncrackable.
If you really know what your own personal doing, even with good security passwords or phrases, wireless systems can be hacked and here’s how…….
When a wireless system user uses internet these people generate data “packets”.
These types of data packets are transported between the wireless NIC cards and the wireless access stage using radio waves anytime the computer/device is linked to the access point.
It may create a certain number of packets per day, depending on how long the user utilizes thier computer with web.
When more users tend to be connected to one access stage, the more data packets tend to be generated.
You have to find the wireless signal
This really is done by using “View Accessible Wireless Network”
More helpful tools are Kismet as well as NetStumbler. Kismet has a much better way because it can capture wireless signals that are not transmitting their SSID.
After getting located a wifi networking you can always connect to that networking if it is not using authentication or encryption.
If it is applying encryption or authentication you then have to use a wifi hacker software, specially made for these kind of work.
As soon as Wireless Hacker software has hauled enough packets it will start off reading the captured data gathered from the data packages and crack the key supplying you with access.
Protect Your Wireless Network from Getting Hacked
Set up your network, not to ever broadcast your SSID. This is done during the setup on the wireless router.
You have to hange the default router get access to something else.
If the tools you're using supports the idea, always use WPA or WPA 2 because it gives you a great deal better encryption which is still might be broken but much more challenging.
Always make sure to check for revisions to your wifi router.
Always turn off your router for all those not using it.
