MITRE ATT&CK
T1204.002 Malicious File

The sample uses OOXML remote template injection, indicating an attempt to download and execute a malicious template from the URL http://proserpinus.online/quill/gESUgsT.dot. This technique is often used to deliver secondary payloads. The document body itself appears to be a legitimate-looking order from the Ministry of Defence of Ukraine, likely intended to add a veneer of authenticity to the malicious download prompt.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://proserpinus.online/quill/gESUgsT.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://proserpinus.online/quill/gESUgsT.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.
