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

The RTF file contains embedded OLE objects, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be activated, likely leading to the execution of embedded code. No document body or script content was available for further analysis, limiting the ability to determine the exact payload or family. The primary IOC is the extracted OLE object data file.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE
