T1566.001 Spearphishing Attachment
The RTF file contains OLE object data and an objupdate directive, indicating an attempt to embed and activate external content. While no specific document body or script content was provided for detailed analysis, these heuristics strongly suggest a malicious intent, likely to exploit OLE vulnerabilities or deliver a secondary payload. The presence of multiple high-severity heuristic firings supports a high confidence in the malicious nature of the file.
Heuristics 3
-
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.
-
\objupdate forces OLE activation high RTF_OBJUPDATERTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
-
OLE object data medium RTF_OBJDATARTF contains 2 \objdata section(s) — embedded OLE objects
