Microsoft Copilot has a massive security flaw. In this video, we break down how threat actors turned Microsoft's AI assistant into a dangerous, one-click data exfiltration weapon.
Imagine clicking a single link, or visiting a compromised website, and having your entire enterprise database, private emails, or proprietary code silently drained through your AI assistant. It sounds like science fiction, but security researchers have exposed a devastating vulnerability in Microsoft Copilot that turns the AI against its own users.
