MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF document contains embedded OLE object data and uses an \objupdate directive, indicating an attempt to exploit a vulnerability for client execution. The presence of objdata suggests the embedded object is intended to be activated, likely to download and execute a secondary payload. The specific exploit and payload are not directly identifiable from the provided evidence, leading to an unknown family classification.

Heuristics 2

  • \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
