DNS Hijacking on Public Wi-Fi: A Growing Threat to Credential Security
In July 2026, cybersecurity researchers identified a campaign where threat actors compromised Wi-Fi gateways in hotels and conference centers to perform DNS hijacking attacks. By altering DNS settings, attackers redirected users attempting to access Microsoft 365 services to fraudulent login pages, thereby harvesting corporate credentials. This method allowed attackers to intercept sensitive information without directly compromising user devices.

The use of DNS hijacking in such environments highlights the need for enhanced security measures and user vigilance when connecting to public networks.
