MITRE ATT&CK
T1204 User Execution: Malicious Link T1566 Phishing T1059 Command and Scripting Interpreter

The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to execute embedded content when the user enables editing. The document body itself is a lure, presenting academic content to mask the malicious intent. The primary mechanism appears to be the exploitation of OLE object handling within RTF documents.

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
