T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects, indicated by RTF_OBJDATA and RTF_OBJEMB heuristics. The RTF_OBJUPDATE heuristic specifically points to the objupdate directive, which forces OLE object activation, suggesting an attempt to automatically execute embedded code. An extracted artifact, objdata_00_off00000062.bin, further supports the presence of potentially malicious embedded content. Without a document body or script content, the exact payload and delivery mechanism remain unclear, leading to an unknown family classification.
Heuristics 4
-
\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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
