Cyber attackers can hide malicious content in seemingly normal documents like Word, Excel, or PDFs, using concealed text or metadata to exfiltrate sensitive data. These tactics exploit trusted applications and AI system vulnerabilities to bypass security measures. #CrossPromptInjection #MetadataExfiltration
Keypoints
- Attackers embed malicious code in common document formats to hide exfiltration payloads.
- Hidden text or metadata can be used to extract sensitive information without detection.
- Exfiltration can occur when users open or interact with compromised files or applications.
- Microsoft highlights vulnerabilities like Cross-Prompt Injection that can manipulate AI agents.
- Indirect prompt injection targets AI systems with tool-calling features, risking data leaks.
