MITRE ATT&CK
T1204.002 Malicious File T1059.005 Visual Basic

The critical heuristic firing indicates exploitation of CVE-2017-0199 via an OLE2Link object, which is designed to load remote content. The extracted URL, https://loooooooooooooooooooog.com/0jyqOc, is the target of this exploit. Although the VBA project itself contains no executable statements, the OLE object's functionality is sufficient to download and execute a second-stage payload.

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
    Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
