Hacking Prevention – Hacking WPA/WPA2 and WEP WI-FI

Hacking WEP protected WI-FI

 

What is WEP protected WI-FI?

Short for Wired Equivalent Privacy, WEP is a security algorithm for IEEE 802.11 (type of connection) wireless networks.Its intention was to provide data confidentiality comparable to that of a traditional wired network. WEP was once widely used and was often the first security choice presented to users by router configuration tools.

How do you hack a WEP Protected WI-FI connection?

This hack involves the usage of 2 applications, CommView and Aircarck-NG GUI. The hacker will use CommView to receive a list of available networks in his area. He selects one of the networks (usually the one with the best connection) and starts collecting packets from the network and puts them into a .cap file (this only works on WEP networks). Once he has collected the sufficient amount of packets (at most 20000 packets) he may use the Aircarck-NG GUI application to open the .cap file and attempt to crack the password.

How does this type of hack work?

A hacker uses an application to acquire a packet from the network he is attempting to hack. For those who don’t know what a packet is, a packet is the unit of data that is sent between an origin and a destination on the Internet. After a long period the application should have collected enough packets (data) to crack the wifi’s password.

How do I protect myself from this hack?

Unfortunately there isn’t a lot that one can do to prevent this from happening to them because WEP is very out dated. The only things that you can do is either get a second level of security or changed your wifi’s security from WEP to WPA.



Hacking WPA and WPA2 protected WI-FI

What is WPA protected WI-FI?

Short for Wifi Protected Access, WPA and WAP2 are security protocols and security certification programs developed by the wifi Alliance to secure wireless computer networks. These security protocols were made plainly because researchers had discovered a big weakness in the older WEP security protocol.

How do you hack a WPA protected WI-FI connection?

There is currently only one known way of hacking into a WPA or WPA2 protected wifi connection and that’s called a brute-force or dictionary attack. In order for someone to do this hack he/she is required to have an software that uses a dictionary attack list to figure out the password. A dictionary attack list is basically a really long list of known passwords.

How does this hack work?

The software that the hacker uses basically takes the long list of known passwords and puts them in one by one until it hopefully comes to one that works. If the all the passwords from that dictionary list doesn’t work then the hacker will attempt the hack again with another dictionary list (there are a large number of dictionary lists that can be used) or he will try connecting to a different network.

How do I protect myself from this hack?

This is actually a very simple thing to do plainly because WPA and WPA2 are already well secured. All you need to do is create a password that is completely absurd for example: H6&weH5eGq#. If you’d like to take further countermeasures then you can buy or download a second level of security.
