Microsoft 365 Copilot Caught in ASCII Smuggling Scandal: Sensitive Data at Risk!
Researchers discovered a method to force Microsoft 365 Copilot to harvest sensitive data like passwords and send them to malicious third parties using ASCII smuggling. This involves hidden prompts in emails or attachments, tricking Copilot into exfiltrating data while users remain clueless. Microsoft has since addressed the issue.
Hot Take:
