Recently while traveling, I stayed at a favorite hotel chain. Arriving in the early morning hours, road weary and groggy, I was pleased to end my day’s journey in such a cozy place. Having been a business traveler for over two decades, I was incredibly familiar with the check-in routine.  Pool hours and location, free breakfast at this time and place, call if you need anything and here are your room keys. As I was stepping away from the desk, through my mental fog, I realized a step in the routine had been missed.  

“Oh... What’s the wi-fi password?” I asked. The clerk smiled professionally, “there isn’t one.” “None at all? Nothing?” feeling I must have been misunderstood somehow. “Nope!” she replied with a satisfied smile, proud to confirm that hotel has made things so simple and user-friendly.  

That’s right! Here in the United States in 2024, a hotel chain had an unsecured network. In a world where security breaches regularly grab headlines, this seemed a step backwards.

An unsecured network refers to a Wi-Fi network that does not require any form of authentication, such as a password – or in the case of a typical hotel, last name or room number - to connect. This type of network is open to anyone within range and typically does not use encryption, making it far less secure than networks which do require a password.

I used a hotspot during my stay and afterward did a little research. Was this common? So, it turns out the practice of employing unsecured Wi-Fi networks at hotels is fairly widespread, especially in budget hotels or public areas like lobbies. It is less common in higher-end hotels, which usually require some form of authentication to ensure that only paying guests have Wi-Fi access. This information was consistent with my personal experience.

If this strikes you as a big security concern, you are correct. Connecting to an unsecured Wi-Fi network can expose you to several significant risks, each with the potential for serious impacts on your privacy, security, and even financial well-being.  

Here are the main risks with using an unsecured network and the potential impacts:

1. Man-in-the-Middle (MitM) Attacks

Risk: In a MitM attack, a hacker intercepts the communication between your device and the internet. This means the hacker can see and alter the data being transmitted.

Impact: Sensitive information such as login credentials, credit card details, or personal messages can be stolen or modified without your knowledge. This could lead to identity theft, financial fraud, or unauthorized access to your accounts.‍

2. Eavesdropping/Sniffing

Risk: Hackers can use specialized software to intercept and analyze the data you send over an unsecured network.

Impact: Even if you aren't actively entering sensitive information, hackers can monitor your activity, potentially leading to the collection of personal data such as browsing habits, email contents, or unencrypted passwords. This information can be sold or used for targeted phishing attacks. ‍

3. Malicious Hotspots

Risk: Sometimes, hackers set up fake Wi-Fi networks that mimic legitimate ones. These are called "evil twin" networks. Unsuspecting users may connect to them, thinking they're legitimate.

Impact: Once connected, all your internet traffic goes through the hacker's network, giving them full access to everything you do online. This could result in compromised accounts, stolen data, or malware infections.‍

4. Malware Distribution

Risk: Unsecured networks can be used by hackers to install malware into your device. This could happen through pop-ups, fake software updates, or compromised websites.

Impact: Malware can cause a variety of issues, from slowing down your device to more serious problems like ransomware, where your files are locked and a ransom is demanded to unlock them. Malware can also be used to steal data, spy on you, or take control of your device remotely. ‍

5. Session Hijacking

Risk: If a hacker is on the same unsecured network, they can hijack your active sessions by stealing your session cookies (small pieces of data stored by websites that keep you logged in).

Impact: The hacker can impersonate you on websites, gaining access to your accounts and personal information. This can result in unauthorized actions being taken on your accounts, such as making purchases or changing account settings. ‍

If you find yourself in a hotel – or anywhere else in the modern world – with an unsecured network, it’s not the end of the world. There are things you can do to manage the situation and get on with your personal or business affairs. Below is a list of some basic solutions.  

How to Protect Yourself:

Use a VPN: A Virtual Private Network encrypts all your internet traffic, making it much harder for hackers to intercept or tamper with your data.

Avoid Sensitive Transactions: If you're on an unsecured network, try to avoid logging into sensitive accounts, making online purchases, or accessing confidential information.

Enable HTTPS: Ensure the websites you visit use HTTPS (the secure version of HTTP), which encrypts data between your browser and the website.

Disable File Sharing: Turn off file sharing and ensure your firewall is enabled when connected to public Wi-Fi.

Use Two-Factor Authentication: Enable two-factor authentication (2FA) on your accounts to add an extra layer of security in case your login credentials are compromised. ‍

Knowing and using this information means you can protect yourself and your data, rather than depend on a business or institution to provide the best security. When it comes to cybersecurity, a little bit of caution upfront can safeguard you from potentially catastrophic consequences later.  

Peace of mind is priceless!
