MITRE ATT&CK

The critical heuristic firing for CVE-2017-0199 indicates that the document is designed to exploit this vulnerability. The embedded URL, https://meetbestthingswhichcominginurlifefuxkingassolesegetwayfromyourlife.busines@scanqris.me/ufVLBTZcd-@?3[c%f�y:�k!جԡOk_h�:MusT�����m��b��_, is the likely source of the secondary payload. Although VBA macros were present, they contained no executable statements, suggesting the exploit relies on the OLE object vulnerability rather than macro execution.

Heuristics 3

  • OLE2Link / URL Moniker → remote loader — CVE-2017-0199 critical CVE likely CVE_2017_0199
    Document contains an embedded OLE link object whose URL Moniker points to a remote URL. When the host file is opened, Office follows the link, downloads the URL, and processes the response based on its Content-Type (HTA -> mshta.exe, RTF → Word, etc.) — the documented CVE-2017-0199 primitive. The URL extension is not a reliable filter; servers can return different payloads to Office's user agent.
  • VBA project contains no executable statements low OLE_VBA_MACROS
    Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
