T1059.005 Visual Basic
The critical heuristic firing for CVE_2017_0199 indicates that this OLE file attempts to load a remote resource from the URL http://192.210.175.4/FBO/2/000000000000000%23%23%23%23%23%23%23%23%23%23%23%23%23%23000000000000000000%23%23%23%23%23%23%23%23%23%23%23%23%23%2300000000000O00OO00.DOC. Although no VBA code was found to be executable, the presence of embedded objects and the CVE exploit strongly suggest a downloader or remote code execution attempt.
Heuristics 6
-
OLE2Link / URL Moniker → remote loader — CVE-2017-0199 critical CVE likely CVE_2017_0199Document 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.
-
Secondary embedded PDF body has suspicious static findings high POLYGLOT_CHILD_PDF_STATIC_TRIAGEA valid PDF body was found at a nonzero offset inside another container and its carved contents matched PDF exploit or lure heuristics. This catches polyglots where the top-level magic routes to ZIP/OLE while a PDF reader or downstream parser opens the hidden PDF payload.
-
VBA project contains no executable statements low OLE_VBA_MACROSDocument contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
-
PDF paints image(s) but contains no text operators info PDF_IMAGE_ONLY_LUREPDF has 1 image XObject(s) and the content stream contains no text-emitting operators (BT/ET, Tj, TJ, ', ") in either raw bytes or decompressed streams — this is the screenshot-as-PDF pattern used to bypass text-based scanners and to deliver instructions purely through rendered pixels. It is informational unless paired with invisible links or risky URI context.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne 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.URL http://192.210.175.4/FBO/2/000000000000000%23%23%23%23%23%23%23%23%23%23%23%23%23%23000000000000000000%23%23%23%23%23%23%23%23%23%23%23%23%23%2300000000000O00OO00.DOC
