Follow these 5 rules to stay safe on Wi-Fi

Published

on

Free Wi-Fi spots are convenient and save users a lot of money. However, they are also perfect for hackers to pick up your personal information. NordVPN offers these rules to safe online.

Free Wi-Fi at cafes, airports, restaurants and city streets is used by almost everyone who’s traveling – but how many people take an extra step to make sure their browsing is not only convenient, but also safe?

Last year, NordVPN (Virtual Private Network) released safety tips for public Wi-Fi, but the number of public Wi-Fi scams only seems to be increasing, showing that people still don’t treat their online security seriously. According to privatewifi.com study, 79% of respondents still don’t use a VPN when they go on public Wi-Fi. According to NordVPN’s recent survey,  almost 35% of respondents still didn’t know such obvious rules that, for example, it was dangerous to shop online on a public network.

Most common ways that a hacker can take advantage of an unprotected Wi-Fi spot:

1. Honeypot Wi-Fi. The most common threat is still a hacker positioning himself as a Wi-Fi hotspot – the so-called honeypot Wi-Fi. When that happens, a Wi-Fi user will be sending their information to a hacker instead to a legitimate Wi-Fi spot – and that could include credit card information, private emails, and any other sensitive information. This technique is very easy for hackers, as Wi-Fi spots rarely require authentication to establish a connection.

2. Wireless sniffers. Hackers can be using sniffers, a software designed to intercept and decode data when it is transmitted over a network. Wireless sniffers are specifically created for capturing data on wireless networks, but are normally used by IT specialists to monitor the health of a network and diagnose problems. When a sniffer falls into a hacker’s hands, it can be easily used to monitor and decode another person’s private data.

3. Shoulder surfing. When an Internet user finds themselves in a crowded coffee shop or an airport, there might be data thieves lurking around, who will watch over a shoulder to memorize passwords or credit card information that one enters into their device. Just as it’s important to be careful when entering a PIN number into an ATM machine, it’s important to make sure no one is looking over a shoulder when going online at a public Wi-Fi spot.

How can an Internet user protect themselves when they go online at a public hotspot?

Actually, it’s really simple – just a few easy rules need to be followed – and they will be safe on any public network.

1. Use a VPN. The best and most effective way for any traveler to protect their data is to use a VPN (Virtual Private Network). A VPN service encrypts all the traffic flow between the Internet and a device thus hiding user’s IP address. Recently, VPNs have become a mainstream tool and quite a few have been remodeled to be very user-friendly. For example, with NordVPN users only have to turn to ON button, and they will be connected. The app (for Windows, Android, Mac or iOS) will then choose the fastest server to connect to. It’s also important to be aware of free VPNs that typically rely on third party advertisers to cover the costs. In addition to protecting one’s online activities, a VPN will also help access banned sites in a different country (such as Facebook in Vietnam or Wikipedia in Turkey).

2. Use a firewall. It’s important to make sure firewall is turned on before going online, especially on a public Wi-Fi spot.

3. Disallow automatic wireless network connection. Make sure automatic wireless connection are not turned on, and Wi-Fi is turned off when it’s not being used – this will prevent hackers from automatically connecting to one’s device.

4. Sharing settings should NOT be Public. To prevent anyone from finding and accessing one’s device, it’s important to make sure System’s Settings are not set to Public sharing.

5. Be vigilant. It’s always important to know who’s around to avoid shoulder surfing or any other suspicious activities.

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entries via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.

5. The competition is only open to South African residents.
