MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains embedded OLE object data and triggers an object update, indicating an attempt to exploit a vulnerability. The presence of `RTF_OBJDATA` and `RTF_OBJUPDATE` heuristics strongly suggests a malicious OLE object is embedded. The `objdata_00_off00000d4a.bin` artifact is the decoded content of this object, likely containing shellcode or a dropper. The attack pattern is inferred from these indicators, pointing towards a malicious attachment designed to exploit Office vulnerabilities.
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
