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

The RTF file contains an OLE object that leverages CVE-2017-0199 to automatically link to a remote URL. This technique is commonly used to download and execute malicious payloads. The embedded URL 'http://bit.ly/2hdOnri' is the primary indicator for the second-stage download.

Heuristics 6

  • CVE-2017-0199 (OLE2Link / remote URL Moniker) critical CVE likely CVE_2017_0199

  • Automatically linked OLE object high RTF_OBJAUTLINK
    RTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
  • OlePres presentation stream in RTF OLE object medium RTF_OLEPRES_STREAM
