JSON data can contain base64-encoded data within certain attributes. For example:
{ "user": { "id": "12345", "name": "John Doe", "profilePicture": "data:image/png;base64,iVBORw0KGgoAAAAN...", "photos": [ { "id": "photo1", "description": "A scenic view", "image": "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYAB..." }, { "id": "photo2", "description": "A portrait", "image": "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQ..." } ] }, "metadata": { "timestamp": "2024-12-24T12:00:00Z", "source": "Generated Example" }}Deep CDR can be configured to perform an in-depth inspection of such data by:
- Decoding base64-encoded content.
- Recursively sanitizing the extracted data.
- Re-encoding the sanitized data in base64.
- Reinserting the processed data back into the JSON structure.
