T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects, specifically triggering critical heuristics for Equation Editor vulnerabilities. This indicates the document is designed to exploit the Equation Editor component to execute arbitrary code. No document body text or scripts were extracted, limiting further analysis of the payload's intent. The presence of the Equation Editor CLSID and object class strongly suggests an exploit targeting this component.
Heuristics 6
-
Ole10Native stream in RTF OLE object high RTF_OLE10NATIVE_STREAMRTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
-
Equation Editor CLSID critical RTF_EQUATION_EDITOREquation Editor OLE CLSID found inside an OLE object — exploited by CVE-2017-11882 / CVE-2018-0802 / CVE-2018-0798
-
Equation Editor object class critical RTF_OBJCLASS_EQUATIONObject class 'equation.3' references Equation Editor
-
OLE object data medium RTF_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
-
Embedded URL info EMBEDDED_URLOne 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.URL http://schemas.microsoft.com/office/word/2003/wordml
