MITRE ATT&CK
T1204.002 Malicious File

The OOXML document contains heuristics indicating remote template injection and external relationships, pointing to a malicious external resource. The embedded URL, http://outlooksyn.com/FpUCu5h6W2/R/YHXCCUK7bk34tzd6GA2AAAATqzjlQ4FwFifvY2EpuSOyN+L1n/16mONopqdw8+w6xh4qXcxhOLWxvIZbHxRr6y5A/kdSgdL, is highly suspicious and likely serves as the download location for a secondary payload. The document's structure suggests it's designed to trick the user into interacting with this malicious resource.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://outlooksyn.com/FpUCu5h6W2/R/YHXCCUK7bk34tzd6GA2AAAATqzjlQ4FwFifvY2EpuSOyN+L1n/16mONopqdw8+w6xh4qXcxhOLWxvIZbHxRr6y5A/kdSgdL) — 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://outlooksyn.com/FpUCu5h6W2/R/YHXCCUK7bk34tzd6GA2AAAATqzjlQ4FwFifvY2EpuSOyN+L1n/16mONopqdw8+w6xh4qXcxhOLWxvIZbHxRr6
  • 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.
