OOXML clickable image phishing/form lure medium OOXML_CLICKABLE_IMAGE_FORM_LURE

Workbook uses a large embedded image as the visible document body and attaches a click-through external hyperlink to that image. The target is a form/collection service or the drawing contains download/view lure text, which is a common credential or document-phishing pattern rather than benign workbook data.
External hyperlinks (1) low OOXML_EXTERNAL_HYPERLINKS

Document contains 1 external hyperlink — clickable URLs are stored as external relationships. First target: https://forms.gle/6oUX7RYfWXRVpwVn7
