MITRE ATT&CK
T1204.002 User Execution: Malicious File

The sample is an OOXML document that utilizes remote template injection, indicated by the heuristic firing 'OOXML_REMOTE_TEMPLATE'. The embedded URL 'http://k22012.c1.biz/paypal.dotm' is highly suspicious and likely serves as a lure to download a malicious template. The document body contains a list of names and contact information, which may be used to add legitimacy or target specific individuals.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://k22012.c1.biz/paypal.dotm) — 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://k22012.c1.biz/paypal.dotm
  • 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.
