Everyday Cybersecurity Practices Experts Say Can Put Your Personal Data at Risk

You might hear the word “cybersecurity” and think it has nothing to do with you, but it doesn’t. A cyberattack occurs approximately every 39 seconds, with global breach volume increasing by approximately 18% year-on-year. And cybercrime is expected to cost businesses and individuals $10.5 trillion this year. Another way these criminals get your information is through your smartphone.

Let’s face it, your phone probably has more personal information than your wallet ever did. Yet millions of people engage in one phone habit almost every day 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 online threats. Here’s why this habit is dangerous, and what you can do to protect yourself.

Why Public Wi-Fi Remains a Favorite Tool of Cybercriminals

Public Wi-Fi networks are designed for convenience, not security. Many open networks lack the protections found on private home networks, making it easy for hackers to intercept data traveling between your device and the Internet. Most of the time, people leave their WiFi on all the time, but it can open 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 to be legitimate. Once connected, victims can unwittingly disclose login credentials, personal information, and financial account information.

Many smartphones automatically connect to previously used Wi-Fi networks without requiring the user’s permission. While this feature is convenient, it can also create opportunities for hackers to use trusted network names. An attacker can set up a fake 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 May Be Disclosed

Most of us think that checking email or scrolling through social media on public Wi-Fi is harmless. However, someone with bad intentions will often target login credentials because those usernames and passwords can open multiple accounts. If a hacker gets access to your email account, they can reset your banking, shopping, and financial services passwords. Personal information collected from compromised accounts can also be used for identity theft or phishing attacks. Even if websites use encryption, social networks can still cause problems.

Five Ways to Protect Yourself While Using Your Phone

That being said, there are times when you may need to use public WiFi. You don’t need to be afraid to connect. There are some things you can do to protect yourself from potential criminals. Here are five steps we recommend you take.

1. Turn off automatic Wi-Fi connection

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

2. Use Mobile Data When Possible

Your mobile connection is generally more secure than an anonymous public Wi-Fi network. Carriers use encryption and security protocols that make interception very difficult. While data limits may bother some users, using mobile data for banking and other sensitive tasks is often worth the trade-off.

3. Avoid Banking on Social Networks

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

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 months. Research has shown that a significant percentage of users roll back operating system and application updates despite security recommendations. In fact, most Americans think these updates make their phone worse. But staying informed helps close potential security gaps before hackers exploit them.

5. Use Strong Security Features

Screen lock, biometric authentication, and two-factor authentication provide important layers of security. Even if someone does access your device or account credentials, additional security measures can prevent them from proceeding. Strong passwords are always important, especially for email accounts that serve as access tools for other services. A few extra seconds during login can prevent huge financial and personal losses later.

Small Changes Can Prevent Big Problems

The convenience of free Wi-Fi often makes people forget the dangers associated with it. Cybercriminals​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ should rely on routine behavior and distractions to find opportunities to steal information. Simply disabling automatic Wi-Fi connections, avoiding sensitive transactions on social networks, and keeping your device updated can greatly reduce your risk. These practices require very little effort but can provide reasonable protection for your finances and personal information.
