We all love free things. Especially when we can use them as tools to greater benefits. One of them is free WiFi offered today by many public and private individuals. What we don’t know is that this free WiFi has many risks. Whether you are a user or a provider of the free WiFi, the risks are eminent.

There are some people who are so evil they decide to set up free Hotspots just to get their next victims. These sites can various names that appear fishy from the onset. Others have deviced the crooked method of using the names of known nearby locations such as McDonald’s and others. Others go to the extent of using the man-in-the-middle (MITM) attack on your web trabffic.

Initially, WiFi networks were being protected by the Wireless Encryption Protocol (WEP). However, it was found to be very weak and could be hacked into even by amateur hackers. This led to a new encryption protocol called the WiFi Protected Access (WPA). This protocol was still found to be faulty given that it could be breached with simple tools. If the public network you are using is being ‘protected’ using this method, you are at risk of being hacked.
How to Stay Safe

- Use a VPN to surf the net when on a public network. Thus will keep you safe from people who use the network to access your data. Keep in mind that a VPN is meant to keep your browsing private from the bad guys.
- Given the option, only go for https sites and keep off http ones. These ones can be seen before the web address of the site you need to visit. To put it shortly, the ‘s’ in https stands for ‘secure’ meaning that the use of this protocol makes it safer to use the net.
