Google warns public WiFi can expose users to hackers stealing personal data.
Smartphone scams surged in 2024, causing losses of about $400 billion.
Users should avoid public WiFi for banking or shopping and keep devices updated.
Free WiFi has become a part of modern life. Whether it’s at an airport, cafe, or hotel lobby, public networks often come to the rescue when mobile data runs low. For many, it feels like an innocent convenience which can be used to check messages, stream videos, or make quick online payments without spending data. However, Google’s latest warning is telling a very different story. Google in its Android: Behind the Screen report on text-based scams has raised concerns over the safety of public Wi-Fi, advising smartphone users to avoid them. According to the tech giant, such networks are open targets for cyber attackers who can use weak security measures to exploit and reach private information.
SurveyWhy free WiFi networks are risky
Public Wi-Fi might appear secure, especially if it requires a password or is originating from a trustworthy source, like a cafe or hotel. However, Google says this is an easy entry point for attackers. Once you’re connected, hackers can intercept or monitor the data that flows between your device and the internet.
This means that even your personal information, such as banking credentials, private messages, and even login details, are vulnerable. Sometimes, attackers are able to plant malicious software on your phone without you noticing. Google’s advisory warns users to avoid using public WiFi for activities involving sensitive information, especially online shopping, banking, or accessing personal accounts.

The warning is not just about WiFi; it reflects a much bigger issue. Smart phone scams have grown into a global menace, costing consumers money and peace of mind. Google’s report notes that these scams have turned into a massive underground industry, with criminals using new methods to reach victims.
Smartphone-related scams alone have caused losses of about $400 billion in 2024. Scammers now buy up stolen phone numbers, subscribe to phishing-as-a-service platforms, and fire off waves of fake messages crafted to pilfer data. These scams are getting smarter, more personal, and a lot harder to detect.

Why should you be concerned?
Digital transactions and UPI payments have swiftly made smartphones an essential part of everyday life in India. From ordering food to paying bills, millions rely on their devices for convenience. But this very dependence is what increases our vulnerability. Connecting to free WiFi at railway stations, airports, or local cafes could put your personal and financial data at risk.
Experts dealing in cybersecurity in India, too, have reported an increase in text-based scams and phishing targeting smartphone users. In such a scenario, the warning from Google becomes very timely with a reminder to be cautious about where and how we connect to the internet.

How to keep yourself safe from such scams?
The most important thing is to avoid using free Wi-Fi as much as possible. Mobile data or a personal Wi-Fi hotspot are much better options for safe browsing. However, if you cannot avoid using public Wi-Fi, do not use your banking app or make online purchases while being connected to it. Another important step is to keep your device up to date. Regular software updates patch security flaws that attackers can try to exploit. Google also encourages users to stay alert when receiving unexpected messages or calls, especially those asking for personal data or payment information.
