Learn Cyber Security in Bangla

If you want to stay safe while using public WiFi, you need to know what the potential threats are. To provide you with the tools to work as safely and securely as possible in public spaces, we developed a list to help you identify 7 dangers of public WiFi and what you can do to protect yourself.

1. Theft of Personal Information

One of the most serious and common threats concerns theft of personal information. Personal information comes in many forms:

Login credentials
Financial information
Personal data
Pictures

If a hacker gets access to your computer or other personal devices through a compromised public WiFi connection, they could have free rein over everything stored. For example, they might get access to your login credentials and log into your bank’s or credit card’s website.

Once hackers obtained your details, they can log in to your personal pages and cause damage to your finances and reputation. If they don’t get full access to the data on your computer, they could still intercept information you are sending over the Internet. This threat will be explored in more detail shortly.

2. Cyber Attacks on Businesses

Business travellers and others who are on the road throughout the day may connect to public WiFi to check their emails, download files, review customers’ information, and perform various other tasks that require a network connection.

Most businesses have security measures in place to reduce the risk of connecting over WiFi, but if you or your colleagues need to log into some sort of security tool to get access to the company’s network, there are still risks with using a public connection.

For instance, you never know what the WiFi provider might track. A lot of public connections are free to use but that does not mean there is not a cost involved. The WiFi provider might be tracking everything you do on the WiFi connection and sell your data to advertisers.

A good way to think about it is if you are not paying to use a service, someone else might be paying them for data about their users. You also cannot always assume you are connecting to a legitimate WiFi service, which brings us to the next potential threat.

3. Man-In-The-Middle Attacks

A man-in-the-middle attack happens when someone “impersonates” a legitimate public WiFi service to trick you into connecting. For example, say you are staying in a SleepTight hotel for the night. The hotel offers free WiFi to its guests so you power up your laptop, turn on WiFi and see a network called “SleepTyte”. If you are not paying close enough attention, you might miss the slight misspelling.

In fact, the SleepTyte network is actually someone in a room down the hall who has their own hotspot set up to lure unsuspecting guests. When you connect to it, the Internet works as expected so you would not think twice. But in reality, everything you do while on that connection goes through the hacker’s computer. Those “men-in-the-middle” could have access to all your login information, passwords and anything else you do while on that WiFi connection.

4. Unencrypted Connections

When you connect to a website that supports encryption, the data that goes back and forth gets encrypted using a secure key. If someone were to intercept that data without the possession of the key, they wouldn’t be able to read it – the data would look like unreadable computer code.

Not all websites offer encryption though. You can tell by the HTTP prefix stated before the domain name. If it starts with HTTPS, it is an encrypted site. If the web address just contains HTTP, it is not encrypted.

When you are connected to a public WiFi network, anyone within range of your computer can intercept everything you send or receive. If you are connected to an unencrypted website, it will all be fully readable. How can someone intercept your network communication? They use the next listed threat.

5. Packet Sniffing / Eavesdropping

Anyone connected to the same WiFi network as you can eavesdrop on what you send and receive using a tool called a packet analyzer or packet sniffer. These tools provide the possibility to view everything transmitted over the WiFi network, provided it is not encrypted.

These tools are not inherently bad. Like many tools, you can use them for good or bad purposes. Packet sniffers let network administrators troubleshoot connection problems and other performance issues with their wireless networks (good). On the other hand, they also let hackers intercept other users’ information and steal anything of any value (bad).

6. Malware Distribution

Another threat that can occur while using public WiFi, is the implementation of malware on your device. Malware exists in many forms:

Viruses
Worms
Trojan horses
Ransomware
Adware

If someone on the same public WiFi as you has bad intentions, they could plant malware on your computer if it is not protected properly. A suspect WiFi provider could use the hotspot itself to infect your computer with one or more of these threats.

It could be as simple as using the WiFi network to place ads on every website you visit. The website itself does not run ads, but the WiFi service can overlay them on top of other websites.

In that case, the ads would normally disappear once you disconnect from the WiFi and go back to your home or office connection. In more serious cases, they could install malware on your personal devices that would persist across all connections.

7. Session Hijacking

Session hijacking is another public WiFi security threat. In this case, an attacker intercepts information about your computer and its connection to websites or other services. Once the attacker has that information, he can configure his own computer to match yours and hijack the connection.

For example, hackers could hijack your connection to your bank’s website after you log in. From the bank’s end of the connection, it would look like your computer and since you are already logged in, the attacker would have access to everything in your account.

How to Protect Yourself From the Dangers of Public WiFi

If you need to use public WiFi, there are several things you can do to help protect yourself from these threats. Some are more effective than others, but it is good to keep in mind that hackers usually aim for the path of least resistance. If you have taken steps to protect yourself, they will more than likely move on to an easier target.
