Google has warned smartphone users against relying on public Wi-Fi networks, emphasizing that this common practice could expose their data and privacy to real risk.
In its new advisory, "Beyond the Screen," published in October 2025, the company explained that public Wi-Fi networks are often unencrypted, making them easy targets for hackers who can intercept data transmitted over them or create fake hotspots to deceive users.
Google cautioned against entering any sensitive information—such as bank account details or passwords—while connecting to such networks, stressing the importance of regularly monitoring bank accounts and installing the latest system updates and security patches.
The company also confirmed that using a reliable Virtual Private Network (VPN) or switching to mobile data are safer options than relying on open Wi-Fi networks.
A number of cybersecurity experts concurred with Google's warnings. Dr. Mani Neri, a cybersecurity lecturer at Oxford Brookes University, said, "Many public Wi-Fi networks are unencrypted, making them vulnerable to exploitation by hackers." He added that some attackers might create fake networks that look just like the real ones to lure users into connecting.
Oliver Buxton, a security expert at Norton, pointed out that "data transmitted over many public networks is sent in plain text, making it easy for cybercriminals to intercept."
Jake Moore, a security consultant at ESET, believes the risk from these networks "is not as high as it once was, but it still exists."
Dr. Neri explained that the level of risk depends on the device's configuration and how it is used, adding that "avoiding logging into sensitive accounts, such as email or banking accounts, is a crucial step when using a public Wi-Fi network."
