MITRE ATT&CK
T1204 Malicious Link T1059 Command and Scripting Interpreter

The document utilizes OOXML remote template injection and external relationship heuristics, indicating an attempt to download a secondary payload. The primary IOC is the URL pointing to an Access database file, which is likely malicious. The document body contains organizational information, likely a lure to disguise the malicious intent.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://glove16.militora.ru/DESKTOP-CNEIOBV/pretend83/ending/intention.accdb) — 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://glove16.militora.ru/DESKTOP-CNEIOBV/pretend83/ending/intention.accdb
  • 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.
