Free WIFI – Should I Be Concerned
Should you do your banking on one or any financial transactions , such as shopping on free open wifi networks.
These are open wifi networks , which means that traffic , your internet surfing is not encrypted , that means people ( bad guys ) can see what you are doing.
There are 3 ways you can be attacked
- There are “man in the middle attacks” where a hacker puts themselves between 2 computers and intercepts or changes communication between them
- “Packet sniffers” where people use computers or mobile devices to intercept any information sent over unsecured wifi
- Fake wifi networks which masquerade as legitimate networks in order to steal information
So what do they steal ?
- Use names and passwords for online banking , social media , emails , shopping
So what should you do to prevent this?
- Make sure your antivirus and firewall are on and working
- Connect to the internet using “ public network on your computer “ which means you should not be sharing any files
- Turn off file sharing
- Make sure the websites you visit start with https in the address bar
If you want to do banking , turn off wifi , setup a hot spot with your smartphone and use its internet capabilities , this is far safer or just use your banks app from your smartphone or tablet
The same applies to internet cafes , I would not do any banking on them as they can be a hotbed of insecure browsing due to little security maintenance being done on them.

App Of The Week
Sometimes you need to communicate directly on a frequency only heard by Superman and dogs. The aptly named Dog Whistler app does just that, allowing you to play a vast range of frequencies for canine training, with oscillations ranging from a slow 500 Hz to a fast 5 KHz. Dog Whistler features a motion-detection alarm that will help keep pets off of your furniture, and you can share your custom whistle with a friend over Facebook, Twitter or email once you’ve found the perfect frequency.
