T1204.002 Malicious File: User Execution
T1059.005 PowerShell
The sample is an OLE file that exploits CVE-2017-0199, a known vulnerability for remote code execution. The heuristic firing indicates it uses URL Moniker to load a remote resource from 'https://nuak.link/rCyDRq'. Although VBA macros were present, they contained no executable statements, suggesting the exploit is delivered via the OLE structure itself rather than macro execution. The document body is heavily corrupted, but the presence of the URL and the CVE exploit firing strongly indicate a downloader or initial access mechanism.
Heuristics 3
-
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.

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.
-
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 https://nuak.link/rCyDRq���,M����T�Ȑ�0)��H
