An employee connects to hotel Wi-Fi, receives a familiar Microsoft 365 sign-in prompt, and authenticates. No phishing email. No malicious link. No suspicious attachment. Yet an attacker walks away with a valid, MFA-satisfied session token.
Join hosts Alexandra Moore and John Dilgen as they break down:
- How compromised hotel and conference-center Wi-Fi gateways silently redirect Microsoft authentication traffic
- Why hardcoded DNS, opportunistic encrypted DNS, and MFA may not stop the attack
- How device-code phishing and WPAD abuse expand the campaign’s reach
- Practical defenses—including always-on, full-tunnel VPN, strict-mode encrypted DNS, and Conditional Access controls
Two questions your organization should be asking right now:
- Does your always-on VPN tunnel all DNS and authentication traffic, or do split-tunneling exceptions leave traveling employees exposed?
- Who is permitted to authenticate through the device-code flow, and does each exception have a legitimate business justification?
