Google issues an important warning about public Wi-Fi networks.

Google has warned smartphone users against relying on public Wi-Fi networks, stressing that this common habit could expose their data and privacy to real danger. In its new advisory document "Beyond the Screen" issued in October 2025, the company explained that public Wi-Fi networks are often unencrypted, making them an easy target for hackers who can intercept data transmitted through them or create fake hotspots to deceive users. Google warned against entering any sensitive information—such as bank account details or passwords—while connected to such networks, stressing the need to regularly monitor bank accounts and install 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 agreed with Google's warnings. Dr. Manni Neri, a cybersecurity lecturer at Oxford Brookes University, said that "many public Wi-Fi networks are unencrypted, making them vulnerable to exploitation by hackers." He added that some attackers may create fake networks that resemble the original to lure users into connecting to them. Oliver Paxton, a security expert at Norton, also pointed out that "data transmitted over many public networks is sent in clear text, making it easier for cybercriminals to intercept it." Jake Moore, a security advisor at ESET, believes that the risk of these networks "is no longer as great as it used to be, but it still exists." Dr. Neri explained that the level of risk depends on the device's configuration and the nature of its use, adding that "avoiding logging into sensitive accounts, such as email or bank accounts, is an essential step when using a public Wi-Fi network." Dr. Abel Yeboah-Ofori, Associate Professor of Cybersecurity at the University of West London, explained that "Google is right in its warning, as public Wi-Fi networks are among the most prominent vulnerabilities exploited by cybercriminals." In its report, Google indicates that smartphones and their networks have facilitated our daily lives by improving communication and organization, but at the same time, they have opened the door to a "sophisticated global project for criminals" targeting unsuspecting users to achieve huge financial gains. According to the document, fraud caused losses exceeding $400 billion worldwide last year alone, while a Google survey revealed that 94% of people received fraudulent text messages requesting personal or financial information. **Golden rules to stay safe while using public Wi-Fi networks:** Disable automatic connection to public or unknown networks to avoid connecting to fake networks. Do not download any application or enter personal data in restricted access portals unless absolutely necessary. Check the HTTPS encryption of websites before entering any sensitive data, and avoid unexpected pop-up windows. Verify the identity of the network before connecting to it, especially in public places such as hotels, airports, and cafes. Use a reliable and paid VPN from known developers, and stay away from free or unsecured networks that may pose a greater risk than not using a VPN at all. Source: Daily Mail - RT
