MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF file contains OLE object data and uses \objupdate to force activation, indicating an attempt to exploit vulnerabilities or execute embedded content. The presence of an embedded OLE object suggests a delivery mechanism for a secondary payload. No document body text or scripts were extracted, limiting further analysis of the specific payload.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE

  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
