Google Warns Public Wi-Fi Poses Serious Cybersecurity Risks

In October 2025, Google issued a strong warning to smartphone users about the dangers of using public Wi-Fi networks. The tech giant stressed that these networks can be "unencrypted and easily exploited by attackers," potentially compromising the safety of any data transmitted over them.

Cybersecurity experts largely agree with Google's assessment. Dr. Manny Niri, a senior lecturer at Oxford Brookes University, explained that public Wi-Fi networks often lack encryption, allowing hackers on the same network to intercept users' online activities, including sensitive information like banking credentials and personal messages.

To mitigate these risks, Google and other security professionals recommend that people avoid using public Wi-Fi whenever possible. Instead, they advise using a virtual private network (VPN), visiting only secure websites, or switching to mobile data, which is generally more secure than open Wi-Fi hotspots.

While some experts believe the "blanket advice" to avoid public Wi-Fi altogether is "often overblown," they still caution users to be cautious and disable auto-connect features that could inadvertently connect them to rogue networks.
