T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF file contains a large OLE object with extensive hex-encoded data, indicated by RTF_EXCESSIVE_HEX and RTF_OBJDATA heuristics. The RTF_OBJUPDATE heuristic suggests that this object is designed to be activated, likely to execute embedded code or exploit a vulnerability. The large size of the embedded data points towards a potential payload delivery.
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.
-
Large hex data blocks in OLE object high RTF_EXCESSIVE_HEXRTF contains ~5880KB of hex-encoded data inside \objdata sections — may hide a payload
-
OLE object data medium RTF_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
