MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The OOXML document contains a high-severity heuristic firing for remote template injection, pointing to the URL https://kho.ink/oTBCI. This indicates the document is designed to load external content, likely to execute a malicious payload. The presence of an external relationship further supports this, suggesting the document is configured to fetch resources from a remote location.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://kho.ink/oTBCI) — 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: https://kho.ink/oTBCI
  • 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.
