MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The RTF document contains OLE object data with an \objupdate directive, indicating an attempt to automatically activate embedded objects. This is a common technique for exploiting vulnerabilities or delivering secondary payloads. The decoded OLE object stream, named 'objdata_00_off000004b2.bin', is the primary indicator of malicious activity. No document body or script content was available for further analysis.
Heuristics 3
-
Ole10Native stream in RTF OLE object high RTF_OLE10NATIVE_STREAMRTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
-
\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 2 \objdata section(s) — embedded OLE objects
