MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The sample is an RTF document containing OLE object data and an \objupdate directive, which are strong indicators of an exploit attempt. The heuristics suggest that the embedded OLE object is intended to be activated, likely to trigger a vulnerability and execute malicious code. No specific family could be identified due to the lack of further behavioral or payload indicators.

Heuristics 2

\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
