MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF file contains embedded OLE objects, with one object triggering an update that likely executes a malicious payload. The high-entropy carved artifact suggests a packed or obfuscated payload is being dropped. Without further analysis of the embedded object, the exact nature of the payload and its ultimate goal remain unclear.
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
-
