MITRE ATT&CK
T1203 Exploitation for Client Execution

The presence of an Equation Editor OLE object is a strong indicator of an attempted exploit. While VBA macros could not be extracted due to an unsupported format, the OLE object itself points to a potential exploitation vector. Further analysis would be needed to determine the specific vulnerability targeted and the subsequent payload.

Heuristics 3

  • Equation Editor OLE object high CVE related OLE_EQUATION_EDITOR
    Contains Equation Editor object — related to CVE-2017-11882 / CVE-2018-0802 exploitation, but CLSID presence alone is not the malformed MTEF exploit primitive.
  • Equation Editor shellcode downloads a second-stage payload critical OLE_MTEF_SHELLCODE_DOWNLOAD_URL
    The shellcode reached by the Equation Editor overflow resolves download/exec APIs and fetches a second-stage payload. The URL was recovered by emulating the shellcode's self-decoding stub; an integer-encoded host (e.g. http://000030000706151) is normalised to its dotted-quad form and both spellings are surfaced.
  • 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.
