T1204.002 Malicious File
T1059.005 Visual Basic
The sample is an OLE file that exploits CVE-2017-0199 via a URL moniker to load a remote resource. The embedded PDF also contains suspicious static findings, suggesting it may be part of a multi-stage attack. No VBA macros were found to be executable, but the primary exploit mechanism is clear. The reconstructed URL from the CVE_2017_0199 heuristic is the highest priority IOC.
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 info 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 2 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.
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
-
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://www.w3.org/1999/02/22-rdf-syntax-ns# In document text (OLE body)
