MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The OOXML file contains a clickable image designed as a phishing or form lure, directing users to an external URL. This technique, combined with a call-to-action shape, strongly suggests an attempt to deceive the user into interacting with a malicious link. The URL itself is hosted on typeform.com, a platform often abused for phishing campaigns.

Heuristics 4

  • OOXML clickable image phishing/form lure critical 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://mfy53l5607x.typeform.com/to/w0mXhKyh
  • Call-to-action shape / download button low OOXML_DOWNLOAD_SHAPE
    Document drawing contains a call-to-action phrase ('Click Here', 'Download Now', etc.) inside a shape or text box — a common visual lure used to trick users into enabling macros or visiting a malicious URL
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
