Every Hotel Guest Logged Into the Wrong Microsoft

Описание: Every Hotel Guest Logged Into the Wrong Microsoft
What happens when you connect to hotel Wi-Fi and sign into Microsoft 365?

In July 2026, cybersecurity researchers uncovered a campaign that compromised hotel and conference Wi-Fi gateways by changing a single DNS setting. Instead of attacking Microsoft directly, the attackers redirected victims to convincing Microsoft 365 login pages designed to steal credentials—or even trick users into approving attacker-controlled sessions without revealing their passwords.

This episode reconstructs how the campaign worked, why hotel networks became the attack surface, how the infrastructure was discovered, and what researchers believe links it to previous DNS-hijacking operations.

If you travel for work, use public Wi-Fi, or regularly access Microsoft 365 from hotels, airports, or conference centers, this investigation explains why a legitimate-looking login page isn't always enough to prove you're talking to Microsoft.

Breach Board reconstructs real cybersecurity incidents—from nation-state campaigns to malware, social engineering, and network intrusions—to explain not just what happened, but how the attack actually worked.
