The Everyday Phone Habit Cybersecurity Experts Say Could Put Your Personal Data at Risk

You might hear the word “cybersecurity” and think that it doesn’t have anything to do with you, but that’s not the case. A cyberattack occurs approximately every 39 seconds, with global breach volumes climbing by roughly 18% year-over-year. And cybercrime is expected to cost businesses and individuals $10.5 trillion this year. One way these criminals are getting access to your information is through your smartphone.

Let’s face it, your phone probably has more personal information in it than your wallet ever did. Yet millions of people engage in one phone habit almost daily without thinking twice about the risks: automatically connecting to public Wi-Fi networks. While free internet at airports, coffee shops, hotels, and restaurants may seem convenient, public Wi-Fi can expose users to scams, data theft, and other cyber threats. Here’s why this habit is so risky, and what you can do to protect yourself.

Why Public Wi-Fi Remains a Favorite Tool for Cybercriminals

Public Wi-Fi networks are designed for convenience, not security. Many open networks lack the protections found on private home networks, making it easier for criminals to intercept data traveling between your device and the internet. Most of the time, people leave their WiFi on all the time, but it could be opening you up to unnecessary security risks.

Attackers can use “man-in-the-middle” attacks to secretly monitor activity and capture sensitive information transmitted over unsecured connections. Fake networks known as “evil twins” can also trick users into connecting to a malicious hotspot that appears legitimate. Once connected, victims may unknowingly expose login credentials, personal information, and even financial account details.

Many smartphones automatically connect to previously used Wi-Fi networks without requiring user approval. While this feature is convenient, it can also create opportunities for cybercriminals to exploit trusted network names. An attacker can set up a fraudulent hotspot using the same name as a legitimate network and wait for devices to connect automatically. In some cases, users may not even realize they have joined a fake network.

How Your Personal Data Can Be Exposed

Most of us assume that checking email or scrolling social media on public Wi-Fi is harmless. However, someone with bad intentions will often target login credentials because those usernames and passwords can unlock multiple accounts. If a criminal gains access to your email account, they may be able to reset passwords for banking, shopping, and financial services. Personal information collected from compromised accounts can also be used for identity theft or targeted phishing attacks. Even when websites use encryption, public networks can still pose a problem.

Five Ways to Protect Yourself While Using Your Phone

That being said, there are times when you might need to use public WiFi. You don’t need to be afraid to connect. There are certain things you can do to protect yourself from would-be criminals. Here are five steps we’d recommend taking.

1. Turn Off Automatic Wi-Fi Connections

Disabling auto-connect prevents your phone from joining networks without your knowledge. This gives you the opportunity to verify that a network is legitimate before connecting. It also reduces the chances of connecting to a fake hotspot operated by a criminal. Most smartphones allow this setting to be changed in just a few seconds.

2. Use Mobile Data When Possible

Your cellular connection is generally more secure than an unknown public Wi-Fi network. Mobile carriers use encryption and security protocols that make interception significantly more difficult. While data limits may be a concern for some users, using mobile data for banking and other sensitive tasks is often worth the tradeoff.

3. Avoid Banking on Public Networks

Checking your bank balance may seem harmless, but financial activity is one of the biggest targets for cybercriminals. Public Wi-Fi should never be your first choice when accessing banking or investment accounts. If a transaction can wait until you’re on a trusted network, it probably should. Even security-conscious users benefit from exercising extra caution with financial information. Protecting your accounts is far easier than recovering from fraud later.

4. Keep Your Phone Updated

Software updates often contain security patches that address newly discovered vulnerabilities. Unfortunately, many smartphone owners delay updates for weeks or even months. Research has shown that a significant percentage of users postpone operating system and app updates despite security recommendations. In fact, a majority of Americans think these updates make their phone worse. But staying current helps close potential security gaps before criminals can exploit them.

5. Use Strong Security Features

A screen lock, biometric authentication, and two-factor authentication provide important layers of protection. Even if someone gains access to your device or account credentials, additional security measures can stop them from progressing further. Strong passwords remain essential, especially for email accounts that serve as recovery tools for other services. A few extra seconds during login can prevent significant financial and personal losses later.

Small Changes Can Prevent Big Problems

The convenience of free Wi-Fi often makes people forget the risks that come with it. Cybercriminals rely on routine behaviors and distractions to find opportunities to steal information. Simply disabling automatic Wi-Fi connections, avoiding sensitive transactions on public networks, and keeping your device updated can significantly reduce your risk. These habits require very little effort but can provide meaningful protection for your finances and personal information.
