Every one of us will come to a time when we urgently need to go online but there is no internet access available. And we will try to move around within our proximity to scan for WIFI and betting on luck that we do not need a password to access it.
Assuming you manage to find a WIFI but you need a password. What do you do?
For me, I will identify the WIFI device and try the factory default password. During the dawn of wireless era, this trick usually works but now people are getting more sophisticated and know how to change the factory password. I used to surf all these products websites and get free download WIFI utility tools and default factory password, and compile a list of it.
Nowaday what I will do is before I go to an unfamiliar place, I will google or ask around for information about free or paid WIFI available at where I am going and make the appropriate choice and backup plan if I ever need urgent internet access.
There are times when I want to show off my skills to my peers or impress my new found girlfriend, I will use a stumbling software to scan the air for nearby wireless. A stumbling software can also detect hidden access point and display their SSID.
After finding all available access points, the next thing you need is their respective passwords to get access. I can run the application to decipher the password but this method takes time. The process may take me from twenty minutes to more than an hour.
A faster alternative is to run a packet capture application on the targeted wireless network. Most of the time it will free download WIFI password in the captured packets. Search through the contents of the packets and any sensible human can detect which one is the password. I just copy and paste, and I have access to the wireless.
To use all these techniques and the required software, you need to practice and learn how to analyze a packet. You can start off by using your own WIFI as your training ground.
Do you feel safe using wireless now? A simple solution to protect yourself from online theft is to use a VPN, Virtual Private Network. A VPN protects the information you transmit over the internet and keep it away from preying sniffers.
