About this tag
Token theft is a growing cybersecurity threat that targets authentication tokens rather than passwords, often bypassing multifactor authentication (MFA). On WindowsForum, discussions cover attacks like Kali365, which abuses Microsoft's device-code authentication flow to capture OAuth tokens, and the FlagLeft bug in Microsoft 365 Android apps that allowed token theft from trusted apps. Other threads detail Russian state-sponsored campaigns using token theft via Outlook vulnerabilities, cloud attack techniques stealing Microsoft Entra refresh tokens, and the Storm-237 device-code phishing campaign. Microsoft's introduction of Administrator Protection in Windows 11 aims to defend against token-theft attacks. These posts emphasize that token theft exploits legitimate authentication workflows, making it a critical concern for IT professionals and enterprise security.
