MITRE ATT&CK
T1204.002 Malicious Link: Malicious File

The document contains external hyperlinks, one of which points to a URL shortener. This suggests a social engineering lure designed to redirect the user to a malicious site. The presence of an external relationship to a template file also indicates potential for macro execution or further malicious content delivery. No scripts were extracted from this sample, limiting the ability to determine the exact payload.

Heuristics 4

  • External relationship high OOXML_EXTERNAL_REL
    External target in word/_rels/settings.xml.rels: file:///C:\Users\ekranz\AppData\Roaming\Microsoft\Templates\Quarterly earnings press release.dot
  • OOXML hyperlink points to URL shortener medium OOXML_URL_SHORTENER_HYPERLINK
    Document contains a clickable external hyperlink to a URL-shortener service. Shorteners are not inherently malicious, but they hide the final landing page from static review and are common in spam and phishing lures.
  • External hyperlinks (2) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 2 external hyperlinks — clickable URLs are stored as external relationships. First target: https://tinyurl.com/DCCCBfast
  • 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.
