T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains OLE object data and an ".objupdate" directive, indicating an attempt to embed and activate an object. The heuristic firings strongly suggest exploitation of RTF parsing vulnerabilities to execute embedded content. While no specific script or URL was directly extracted, the presence of OLE object data points towards a downloader or exploit delivery mechanism. The lack of readable document body text and scripts limits further analysis of the exact payload.
Heuristics 3
-
\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 1 \objdata section(s) — embedded OLE objects
-
