MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF file contains OLE object data and heuristics indicate that \objupdate forces OLE activation, suggesting it's designed to execute embedded content. The presence of an embedded OLE object further supports this. No document body or script content was available for analysis, so the exact payload and delivery mechanism remain unclear.

Heuristics 3
