MITRE ATT&CK

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

The RTF document contains an OLE object and uses an \objupdate directive, indicating an attempt to execute embedded content. The document body explicitly instructs the user to 'Enable editing' to view the content, a common social engineering lure to bypass macro security settings and facilitate the execution of malicious payloads.

Heuristics 3

\objupdate forces OLE activation high RTF_OBJUPDATE

RTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
OLE object data medium RTF_OBJDATA

RTF contains 1 \objdata section(s) — embedded OLE objects
Macro/content-enable lure medium SE_ENABLE_LURE

Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
