MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The RTF file contains embedded OLE objects, including a package object and PE header in hex data. This strongly suggests the document is a malicious container for a secondary executable payload. The embedded artifact 'objdata_00_off000000d1.bin' is likely the dropped executable.

Heuristics 5

PE header (with DOS stub) in hex data critical RTF_MZ_HEX

Hex-encoded PE (MZ + DOS stub) found inside RTF — likely an embedded executable payload
Package object class high RTF_OBJCLASS_PACKAGE

OLE Package object — can wrap arbitrary files
OLE object data medium RTF_OBJDATA

RTF contains 1 \objdata section(s) — embedded OLE objects
Embedded OLE object medium RTF_OBJEMB

RTF contains \objemb — embedded OLE object
