MITRE ATT&CK
T1559.001 Component Object Model Hijacking

The file is a Microsoft Office Word document containing an embedded OLE object. Static analysis identified a high-severity heuristic indicating the presence of an Equation Editor OLE object, which is a known vector for exploitation. This suggests the document is designed to leverage a vulnerability within the Equation Editor to execute malicious code.

Heuristics 3

  • Equation Editor OLE object high CVE related OLE_EQUATION_EDITOR
    Embedded OLE object word/embeddings/7kAS.bjZ0m contains the Equation Editor CLSID, the legacy component exploited by CVE-2017-11882, CVE-2018-0802, and CVE-2018-0798.
  • 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.
