MITRE ATT&CK

T1204 User Execution T1204.002 Malicious File T1566 Phishing T1566.001 Spearphishing Attachment

The RTF file contains embedded OLE objects and an instruction to 'enable editing', indicating a social engineering lure to bypass security measures. The presence of ".objdata" and ".objupdate" heuristics strongly suggests the activation of embedded OLE objects, which is a common method for delivering malicious payloads. The document body discusses financial auditing, likely serving as a pretext to disguise the malicious intent.

Heuristics 4

\objupdate forces OLE activation high RTF_OBJUPDATE

Embedded OLE object medium RTF_OBJEMB

RTF contains \objemb — embedded OLE object
Macro/content-enable lure medium SE_ENABLE_LURE
