T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE object data, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this embedded object is forced to activate, likely leading to the execution of malicious code. The high-entropy carved artifact further supports the presence of packed or obfuscated content within the OLE object. The file's SHA256 hash is provided as a primary IOC.
Heuristics 3
-
\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.
