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

The sample is an OOXML document that uses remote template injection, indicated by the heuristic firings OOXML_REMOTE_TEMPLATE and OOXML_EXTERNAL_REL. The document body explicitly prompts the user to 'Enable-Content' to view a 'free curriculum vitae template' from a specific URL, which is a common social engineering tactic to bypass security warnings and download further malicious payloads. The embedded URL is the primary indicator of compromise.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://healthydiet4all.com/word/custom_templates/CV) — a common remote-template-injection vector used by Hancitor, Emotet and many phishing campaigns. Word can fetch and apply the remote template; macros in that template may execute depending on Office policy and trust state.
  • External relationship medium OOXML_EXTERNAL_REL
    External target in word/_rels/settings.xml.rels: https://healthydiet4all.com/word/custom_templates/CV
  • 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.
