Description

Kaspersky experts have investigated the security of public Wi-Fi access points in Mexico City, Guadalajara, and Monterrey.

Impact

Users connecting to unsecured public Wi-Fi networks in Mexico risk traffic interception and surveillance. The widespread presence of WPS-enabled access points increases vulnerability to attacks that exploit this feature, even on networks using WPA2/WPA3. The use of default SSIDs and broadcast of hardware identifiers can aid attackers in targeting specific devices or networks. Additional risks include fake Wi-Fi hotspots (evil twins), malicious QR codes, unsafe public USB chargers, and Bluetooth/NFC-based attacks. These factors collectively increase the likelihood of data compromise for users relying on public Wi-Fi in the surveyed cities.

Defensive guidance

Users are advised to avoid connecting to unsecured public Wi-Fi networks. When public Wi-Fi use is necessary, employ a trusted VPN to encrypt traffic and reduce interception risk. Disable WPS on personal devices and avoid networks with WPS enabled if possible. Prefer cellular data connections or global eSIMs for internet access while traveling. Avoid using public USB chargers, scanning unknown QR codes, and keep Bluetooth and NFC disabled in crowded places. Follow recommended digital hygiene practices to minimize exposure to Wi-Fi-related threats.

Summary

Kaspersky's Global Research and Analysis Team performed passive reconnaissance of public Wi-Fi networks in three major Mexican cities, logging 84,500 signals and analyzing security configurations. They categorized networks into secure (WPA2/WPA3), unsecured (open/WEP), weak (WPA), and undetermined. Approximately 82% were secured with WPA2/WPA3, but over 10% were open and vulnerable to interception. WPS, a known vulnerable feature, was enabled on about 45% of access points, including many with WPA2/WPA3, reducing overall security. The study also noted that many networks use default or manufacturer SSIDs, which can aid attackers in identifying hardware and potential vulnerabilities. The research did not involve active exploitation or traffic interception but highlights ongoing risks in public Wi-Fi environments in Mexico.
