MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains OLE object data and is configured to automatically update and activate these objects, indicating an attempt to exploit vulnerabilities. The presence of `RTF_OBJDATA`, `RTF_OBJAUTLINK`, and `RTF_OBJUPDATE` heuristics strongly suggests that the document is designed to embed and execute malicious content. The extracted artifact `objdata_00_off00000571.bin` is likely the payload or a component thereof. The document body is heavily obfuscated and does not provide clear textual lures.
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.
