MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious File
The RTF file contains OLE object data and uses automatic linking and update mechanisms, indicating an attempt to exploit vulnerabilities for code execution. The presence of an embedded OLE object further supports this. While no specific document body content or scripts were extracted, the heuristics strongly suggest a malicious OLE object is embedded, likely leading to the download or execution of a secondary payload.
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.
