The sample is an Office document that uses a lure to trick the user into enabling macros, a common technique for malware droppers. It contains a remote template injection pointing to http://87.120.84.39/txt/Xkl0PnD8zFPjfh1.wiz, which is likely used to download and execute a second-stage payload. The document body contains a list of industrial parts, presented in Afrikaans, which serves as the lure.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://87.120.84.39/txt/Xkl0PnD8zFPjfh1.wiz) — 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://87.120.84.39/txt/Xkl0PnD8zFPjfh1.wiz
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • 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.
