MITRE ATT&CK
T1204.002 Malicious File

The OOXML document utilizes remote template injection, indicated by the 'OOXML_REMOTE_TEMPLATE' and 'OOXML_EXTERNAL_REL' heuristics. It attempts to pull a malicious template from the URL http://aconitum.xyz/6057188ADC70/mail/mail/fzmZF.dot. This suggests a delivery mechanism designed to trick the user into loading a malicious external resource, likely leading to further compromise.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://aconitum.xyz/6057188ADC70/mail/mail/fzmZF.dot) — 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://aconitum.xyz/6057188ADC70/mail/mail/fzmZF.dot
  • 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.
