T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects that are automatically linked and updated, indicating an attempt to exploit user interaction. The presence of `RTF_OBJDATA`, `RTF_OBJAUTLINK`, and `RTF_OBJUPDATE` heuristics strongly suggests the document is designed to activate these embedded objects. This mechanism is commonly used to download and execute secondary payloads, although no specific script or URL was directly extracted to confirm the exact payload delivery method. The `EXTRACTED_FILE_STATIC_TRIAGE` heuristic further supports the presence of a suspicious embedded artifact.
Heuristics 4
-
Automatically linked OLE object high RTF_OBJAUTLINKRTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
-
\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
-
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.
