Description
In today's cloud-driven landscape, Microsoft Azure and 365 (M365) have become essential tools for businesses worldwide. However, beneath their user-friendly facades lie a landscape rife with potential threats stemming from default configurations. Through years of attacking Microsoft cloud environments during red team engagements I have found commonalities across many companies where overlooking default settings have left them vulnerable.
Very recently I released a new post-exploitation tool for Microsoft Entra ID accounts called GraphRunner. This tool leverages the Microsoft Graph API, which is a fundamental piece of infrastructure for much of Microsoft 365 and Azure. I will demonstrate how this API can be leveraged to perform post-exploitation of a Microsoft Entra ID account to perform reconnaissance, establish persistence, escalate privileges, and ultimately pillage data from services such as SharePoint, Teams, and email.
Throughout the talk, I will present real-world examples that underscore the critical importance of proactive defense. These demonstrations will be supported by practical, hands-on showcases featuring custom-built tools crafted specifically for these targeted attack scenarios.
