A significant security vulnerability has been uncovered in Microsoft 365 Copilot, potentially exposing sensitive organizational information. Researchers have detailed a zero-click data leak flaw that could allow attackers to extract data without requiring any interaction from the user.
This critical security flaw is tied to how Microsoft 365 Copilot, the artificial intelligence assistant integrated into the Microsoft 365 suite, handles prompts and user interactions. The vulnerability could be exploited to trick the AI into revealing internal files, emails, or other confidential enterprise data it has access to, bypassing standard security controls.
The zero-click nature of this exploit makes it particularly dangerous, as a successful attack wouldn’t rely on phishing links or malicious attachments. Instead, it could potentially be triggered through cleverly crafted prompts or interactions that manipulate Copilot’s behavior, leading to an unintentional data leak.
Given the extensive access that Microsoft 365 Copilot has to a company’s digital workspace, including documents, communications, and data, a successful exploitation of this vulnerability could have severe consequences, including massive data breaches.
Organizations using or planning to deploy Microsoft 365 Copilot should be aware of this reported security flaw. Staying updated on patches and security advisories from Microsoft is crucial to mitigate risks associated with this and other potential vulnerabilities in AI-powered tools handling sensitive information. This discovery highlights the ongoing challenges in securing complex AI systems integrated into core business platforms.
