MITRE ATT&CK

T1559.001 Component Object Model Hijacking T1129 Execution through API

The RTF document contains an embedded OLE object that, upon decoding, reveals a PE header. This strongly suggests the RTF is a container for a malicious executable. The ClamAV detection 'Html.Trojan.GenericFakeAV-1' further supports the malicious nature of the embedded content.

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
ClamAV: Html.Trojan.GenericFakeAV-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Html.Trojan.GenericFakeAV-1
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
