MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF file contains an embedded OLE object which, upon inspection, reveals a PE header in hex data. ClamAV signatures confirm this is a malicious trojan (Win.Trojan.Agent-514729). The presence of OLE object data and a package object class strongly suggests this RTF is a delivery mechanism for the embedded executable.

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: Win.Trojan.Agent-514729 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Win.Trojan.Agent-514729
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
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

Extracted artifacts 1
