T1204.002 Malicious File
T1059.005 Visual Basic
The sample is an OLE file that exploits CVE-2017-0199 via a URL moniker to download a remote document. The embedded URL, http://192.3.243.157/wd/v/netsatnetsatnetsatnetsatnetsatnetsat%23%23%23%23%23%23%23%23%23%23%23%23%23%23%23%23nsetsnetsnetsnetsetnsetsnetsnstsnset.DOC, is indicative of a remote loader attempting to fetch a secondary payload. Although no VBA code was found to be executable, the exploit itself is sufficient to initiate a download and subsequent execution chain.
Heuristics 5
-
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 critical 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.
-
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://192.3.243.157/wd/v/netsatnetsatnetsatnetsatnetsatnetsat%23%23%23%23%23%23%23%23%23%23%23%23%23%23%23%23nsetsnetsnetsnetsetnsetsnetsnstsnset.DOC
