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.

LG G7 arrives in SA
LG this week introduced South Africa to its latest premium smartphone, the LG G7 ThinQ, focused on bringing useful and convenient AI features to the smartphone experience.
Powered by the latest Qualcomm Snapdragon 845 Mobile Platform, the LG G7 ThinQ offers 4GB of RAM and 64GB of internal storage to run demanding tasks and apps with. It is equipped with a 6.1-inch Super Bright Display, but the LG G7 ThinQ remains compact enough to use with one hand.
Sporting a new design aesthetic for the G series, the polished metal rim gives the LG G7 ThinQ a sleeker, more refined look, complemented by Gorilla Glass 5 on both the front and the back for enhanced durability. Rated IP68 for dust and water resistance, the LG G7 ThinQ is also awarded MIL-STD 810 c certification, having been subjected to a range of extreme temperature and environment tests designed by the United States military.
The LG G7 ThinQ has an 8MP camera up front, rendering clear and natural selfies, with two 16MP cameras at the back that deliver higher resolution photos with more detail, as well as a Super Wide Angle configuration.
As with other leading brands, LG has evolved its signature camera by including AI functionality. The AI CAM offers 19 shooting modes for intelligence-optimised shots. Users can also improve their photos by choosing from an additional three effect options should the AI CAM recommendation not suit their taste.
The new Super Bright Camera captures images that are up to four times brighter than typical photos shot in dim light. Through the combination of pixel binning and software processing, the AI algorithm adjusts the camera settings automatically when shooting in low light.
Live Photo Mode records one second before and after the shutter is pressed for snippets of unexpected moments or expressions that would normally be missed. Stickers uses face recognition to generate fun 2D and 3D overlays, such as sunglasses and headbands, that can be viewed directly on the display.
New to the G series is Portrait Mode, which generates professional-looking shots with out-of-focus backgrounds. This effect can be generated using both front and rear standard lenses as well as the rear Super Wide Angle lens.
LG G7 ThinQ offers further AI functionality with the inclusion of Google Lens features. Google Lens is a new way to search using the AI and computer vision. Google Assistant and Google Photos allow users to access more information on objects such as landmarks, plants, animals, and books. It can identify text or visit websites, add business cards to contacts, events to the calendar or look up an item on a restaurant menu.
A button just below the volume keys launches the AI functionality. A single tap of this button launches the Google Assistant, while two quick taps launches Google Lens. Users can also hold down the button to start talking to the Google Assistant without the repetition of the OK Google command.
With Super Far Field Voice Recognition (SFFVR) and the highly-sensitive G7ThinQ microphone, the Google Assistant can recognise voice commands from up to five meters away. SFFVR is able to separate commands from background noise, making the LG G7 ThinQ an alternative to a home AI speaker, even when the TV is on. Commands for the Google Assistant have been increased in the LG G7 ThinQ so users can get more done with their voice alone.
“The LG G7 ThinQ is strongly focused on the fundamentals and its launch marks a new chapter for our company,” said Deon Prinsloo, General Manager for Mobile Communication, LG Electronics S.A Pty Ltd. “Through the combination of personalised and useful AI functionalities with meaningful smartphone features, this is LG’s most convenient and in the moment smartphone yet.”
