Microsoft Copilot Bug Could Have Stolen Your Data With One Click

Security researchers discovered a serious vulnerability in Microsoft Copilot, the AI assistant built into many Microsoft products. The flaw, nicknamed SearchLeak, would have allowed hackers to steal your data if you clicked on what appeared to be a normal link. The attack worked by hiding malicious instructions and URLs that Copilot could not detect. Microsoft has since patched this security hole.

This vulnerability affected anyone using Microsoft Copilot in their work or personal Microsoft accounts. If a hacker had successfully exploited this flaw before the patch, they could have accessed your documents, emails, conversations with Copilot, and other data stored in your Microsoft services. The attack required you to click on a specially crafted link, which could have been sent via email, chat, or embedded in a document. Since Microsoft has already released a fix, here is what you need to do:

1. Make sure your Microsoft software and apps are fully updated. On Windows, go to Settings, then Windows Update, and install all available updates.
2. If you use Microsoft 365 or Copilot at work, check with your IT department to confirm they have applied the latest security patches.
3. Review your recent Microsoft account activity. Look for any sign-ins or actions you do not recognize.
4. If you clicked on suspicious links recently while using Copilot, change your Microsoft account password immediately and enable two-factor authentication. This incident highlights the new security risks that come with AI tools. Never click on links from people you do not know, even if they appear in professional-looking documents or emails. Keep all your software updated, as companies regularly release patches for newly discovered vulnerabilities. Enable two-factor authentication on all important accounts, including your Microsoft account. This adds a second layer of protection even if someone gets your password.
