T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE objects, indicated by RTF_OBJDATA and RTF_OBJEMB heuristics. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be activated automatically upon opening the document. This mechanism is commonly used to deliver and execute malicious payloads, such as the extracted objdata_00_off0000004f.bin artifact.
Heuristics 4
-
\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
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
-
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.
