MITRE ATT&CK

T1559 Component Object Model and Distributed Component Object Model T1559.001 Component Object Model and Distributed Component Object Model: Component Object Model

The RTF file contains an embedded OLE object, identified by RTF_OBJDATA and RTF_OBJEMB heuristics. This object includes a PE header within its hex-encoded data (RTF_MZ_HEX), indicating the presence of a hidden executable payload. The large amount of hex data (RTF_EXCESSIVE_HEX) further supports this, suggesting the RTF is a dropper for a malicious binary.

Heuristics 6

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
Large hex data blocks in OLE object high RTF_EXCESSIVE_HEX

RTF contains ~1436KB of hex-encoded data inside \objdata sections — may hide a payload
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
