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

The sample exhibits characteristics of a malicious Office document, including remote template injection and an embedded OLE object. The primary indicator is the external URL 'https://s.tunpok.com/yVqQK', which is likely used to fetch and execute a secondary payload. This suggests a spearphishing attachment delivery method aiming to exploit vulnerabilities for client execution.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://s.tunpok.com/yVqQK) — 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://s.tunpok.com/yVqQK
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • 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.
