MITRE ATT&CK
T1566.001 Spearphishing Attachment

The OOXML file contains a clickable image designed as a phishing lure, directing users to a form hosted on typeform.com. This suggests an attempt to collect user input under a pretext. While the URL itself is currently flagged as benign, the presence of the lure and external hyperlink indicates a malicious intent to deceive the user.

Heuristics 3

  • 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://fxghgg.typeform.com/to/ogs2iMmc
  • 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.
    URL https://fxghgg.typeform.com/to/ogs2iMmc
