T1204.002 Malicious File T1059.005 Visual Basic

The sample is a malicious Excel file that exploits CVE-2017-0199 via an OLE2Link object to download and execute a remote loader from the URL https://getabre.com/GJa61u. Additionally, it contains an OLE Package exploiting CVE-2014-4114, indicating a multi-exploit approach. No VBA macros were found to be executable, but the presence of the exploits and the remote URL strongly suggest a downloader or initial access mechanism.

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.
  • CVE-2014-4114 — OLE Package with executable payload critical CVE likely CVE_2014_4114
    OLE Package CLSID found alongside executable file references — a strong CVE-2014-4114/Sandworm-style package-dropper indicator.
  • 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.
