MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The sample is an RTF document containing embedded OLE object data, indicated by the RTF_OBJDATA heuristic. The RTF_OBJAUTLINK and RTF_OBJUPDATE heuristics suggest that this OLE object is automatically activated upon opening the document. This mechanism is commonly used to execute embedded malicious code or download and run a secondary payload, hence the high confidence in an attack pattern involving OLE object exploitation.
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.
