Heuristics 4

  • ClamAV: Xls.Downloader.Agent08210-9888570-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Xls.Downloader.Agent08210-9888570-0
  • 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/247teeGg5jc3wBLcA
  • 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.
