MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The RTF document contains embedded OLE object data, indicated by RTF_OBJDATA and RTF_OLE10NATIVE_STREAM heuristics. The RTF_OBJUPDATE heuristic suggests that the embedded object is designed to be activated automatically, likely leading to the execution of a malicious payload. No specific family could be identified, and no further IOCs were extracted.

Heuristics 3

Ole10Native stream in RTF OLE object high CVE related RTF_OLE10NATIVE_STREAM

RTF 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_OBJUPDATE

RTF 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_OBJDATA

RTF contains 1 \objdata section(s) — embedded OLE objects
