MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The file is a malicious OOXML document that uses remote template injection and external relationships to fetch a malicious template from the URL http://103.95.99.3/ApothecaryResume.dotx. This indicates an attempt to lure the user into downloading and executing a malicious payload disguised as a resume.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://103.95.99.3/ApothecaryResume.dotx) — 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: http://103.95.99.3/ApothecaryResume.dotx
  • 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.
