ascii smuggling

About this tag
ASCII smuggling is a technique used in prompt injection attacks against AI systems like Microsoft 365 Copilot. It involves embedding invisible or non-printable ASCII characters within prompts to bypass security filters and exfiltrate sensitive data. This method was highlighted in the EchoLeak vulnerability discovered in August 2024, which allowed attackers to manipulate Copilot into performing unauthorized actions without user interaction. The technique underscores broader risks in AI-driven enterprise tools, where attackers can exploit encoding tricks to hide malicious instructions. Microsoft has since worked on advanced security measures, such as AI Security Posture Management, to counter these threats.
