MITRE ATT&CK
T1204.002 Malicious File: User Execution T1059.005 PowerShell

The critical heuristic firing indicates exploitation of CVE-2017-0199 via an OLE2Link object, which attempts to download a secondary payload from the provided URL. The VBA macros are present but do not contain executable statements, suggesting the primary malicious functionality is within the OLE object itself. The extracted URL is the primary indicator of compromise.

Heuristics 2

  • 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
