What it is
Device-code phishing abuses a legitimate OAuth sign-in flow intended for devices that cannot easily display a login screen. The attacker starts the flow, gives the victim a code, and persuades them to enter it on Microsoft's real sign-in page, authorizing the attacker's session without directly stealing a password. The technique predates the current campaign; Microsoft observed it in targeted activity in 2025 before a 2026 operation scaled it with automation and AI-personalized lures.
Why it is rising
Microsoft described a 2026 campaign as an escalation from device-code phishing activity first observed in 2025.
