What is Public Wi-Fi?

Public Wi-Fi is actually the wireless internet service that is available for the public. To provide them with an internet connection no matter where they are. These networks are usually found in different locations which can include places like:

• Cafes and coffee shops
• Restaurants
• Hotels
• Airports
• Libraries
• Shopping malls
• Public transportation hubs (like bus and train stations)

Public Wi-Fi allows you to connect your devices to the internet without needing to use your own personal data plans.

Why Is There Public Wi-Fi?

There were some reasons for offering the public wireless network were introduced to the public so that they have:

• Convenience: It allows people to stay connected to the internet when they are away from their home or the office.
• Customer Attraction: Many businesses give free Wi-Fi to attract customers who may spend more time and money at their enterprise.
• Accessibility: It gives internet access to the ones who may not have access at their home.
• Marketing: Many businesses can use free Wi-Fi to collect data about their customers in order to push advertisements and promote their own services.

Is Public Wi-Fi Safe?

Many free Wi-Fi networks do not use any kind of encryption. Intruders can insert themselves between your device and the network you are accessing. Hackers can also set up crooked hotspots that may look real. Also unsecured networks are also used to distribute harmful viruses like malware and spyware.

How to Check if Public Wi-Fi is Not Safe (Tips)

You know you can check if the Wi-Fi that you are connected to is safe or not. Follow ahead and you will know, because this is important. You should: 

Check Encryption

You should make sure that the Wi-Fi network uses WPA2 or WPA3 encryption algorithms. Ignore any network that is using WEP or no encryption at all.

Verify Network Name

Confirm the exact network name (SSID) with the establishment providing it because there could be similar-looking names that could be rogue hotspots.

Look for HTTPS

Verify the websites are secured with HTTPS which you want to access. You will know when you see a padlock icon in the browser’s address bar. This proves that you have encrypted communication with the website.

Avoid Open Networks

Choose the networks that always require a password to connect. Open networks are more easy to attack.

Check Network Activity

Always check your device’s network activity. If there are any unusual spikes in data usage or an unknown connection then you will be aware of any malicious activity that is happening.

Use Network Scanning Tools

Consider using tools like Find or Wireshark. They help to analyze the network for any possible security threats.

Network Administrator Confirmation

Many places like cafes or airports also have free Wi-Fi available. Just ask their staff to confirm whether the network is authentic or not and whether it has any security measures.

Pro Tip: Another handy tip just for you. Always use different devices for sensitive and non-sensitive tasks. For example, you should use a phone for browsing and a laptop for more secure work. This makes sure that your sensitive device is on a more secure connection.

Security Risks of Connecting to Public Wi-Fi

Now we will tell you about some public WiFi risks. It is quite important and you should know about these. 

Unencrypted Networks

Many free wireless networks do not use any encryption. And that makes it very easy for hackers to catch. And yes they can any data that is being transferred over that network.

Man-in-the-Middle Attacks

In Man-in-the-Middle Attack intruders can tamper with the communications between your device and the WiFi router. And they can have any sensitive data such as login info, emails and even credit card numbers, which obviously you don’t have anyone to have. 

Malware Distribution

Free wireless networks are also used to spread malware to devices that are connected to it. It is very possible that these have viruses, ransomware or even spyware, which can affect your devices. 

Eavesdropping

Without any encryption hackers can eavesdrop on your online activities. This very likely means that they can capture every sensitive information of yours like login details and private communications too.

Session Hijacking

Many hackers can hijack your active sessions on websites or even applications. And they can gain access to your accounts which are not authorized.

Snooping and Sniffing

Cybercriminals use special software kits to eavesdrop on you by Wi-Fi signals. This way they capture data that is being transmitted over that network.

New Emerging Security Public WiFi Risks 

Yes you may know about some of the old fashion ways of hackers to gain access to your private data. But let us tell you also about some of the new ways that they can be used nowadays. These public WiFi security risks are: 

Evil Twin Attacks

Hackers set up fake wireless internet networks that appear so real. And if you connect to these networks, your data is exposed to them and they can access information.

SSL Stripping

In SSL Stripping Hackers downgrade the secure HTTPS connections to unsecure the HTTP connections. This will make it much easier to catch data that is transmitted between the user and the website.

Wi-Fi Pineapple

A wireless internet Pineapple is a device that is used by penetration testers and hackers so that they can run MITM attacks. It can mimic any legitimate wireless networks, capture data and even inject malicious code into web pages.

Advanced Persistent Threats

APTs are long-term targeted attacks. In this hackers can gain access to a network and remain undetected for a very long time. And they keep on gathering sensitive information. Free wireless internet is an entry point for such attacks.

Credential Harvesting

Hackers can also use free Wi-Fi to collect many login credentials from users who don’t suspect anything. They do this by creating a fake login page. 

IoT Device Vulnerabilities

As more Internet of Things devices are connected to free wireless internet, they become special targets for hackers. These devices mostly lack strong security features. Which then makes them very easy to compromise.

Cryptojacking

Hackers can also use free wireless networks to inject evil scripts into users’ devices. By using their computing power they can mine cryptocurrencies without anyone knowing.
