GraphSpy is an initial access and post-exploitation tool designed for Azure Active Directory (AAD) and Office 365 environments with a browser-based GUI. The tool allows security professionals to manage access tokens, perform reconnaissance, and interact with Microsoft 365 services after gaining initial access. GraphSpy provides functionality to store and manage access and refresh tokens for multiple users and scopes, create and poll device codes for authentication, and manipulate multi-factor authentication (MFA) methods including adding new methods for persistence. The tool offers several modules for post-exploitation activities: - File access through OneDrive and SharePoint with download and upload capabilities - Email access and manipulation through Outlook (using either direct web access or Graph API) - Microsoft Teams message reading and sending - Graph API searching across Microsoft 365 applications - Custom API request capabilities with template storage - Entra ID user enumeration and detailed user information gathering GraphSpy runs as a local web application accessible through a browser interface, supporting both light and dark modes. It can be installed via pipx and works across operating systems, with primary testing done on Linux and Windows. The tool supports multiple databases to organize tokens and device codes for different assessment engagements.
