Living off Microsoft Copilot

Whatever your need as a hacker post-compromise, Microsoft Copilot has got you covered. Covertly search for sensitive data and parse it nicely for your use. Exfiltrate it out without generating logs. Most frightening, Microsoft Copilot will help you phish to move lately. Heck, it will even social engineer victims for you!

This talk is a comprehensive analysis of Microsoft copilot taken to red-team-level practicality. We will show how Copilot plugins can be used to install a backdoor into other user's copilot interactions, allowing for data theft as a starter and AI-based social engineering as the main course. We'll show how hackers can circumvent built-in security controls which focus on files and data by using AI against them.

Next, we will drop LOLCopilot, a red-teaming tool for abusing Microsoft Copilot as an ethical hacker to do all of the above. The tool works with default configuration in any M365 copilot-enabled tenant.

Finally, we will recommend detection and hardening you can put in place to protect against malicious insiders and threat actors with Copilot access.
