An unattributed threat actor used AiTM phishing and device code flows to steal M365 session tokens, replaying them to register rogue devices and wipe MFA methods across 79 organizations.

Attackers are abusing the OAuth 2.0 device authorization grant to trick users into authenticating malicious sessions on legitimate Microsoft sign-in pages, bypassing MFA.

The DEBULL PhaaS framework leverages Microsoft device-code phishing and the GraphSpy post-exploitation tool to compromise Microsoft 365 tenants using Storm-2372-style tradecraft.

The Storm-1747 threat actor uses the Tycoon 2FA AiTM phishing kit to bypass multi-factor authentication and maintain persistence in Microsoft 365 and Google Workspace environments.
