T1204.002 Malicious File
T1059.005 Visual Basic
The sample is an Excel file that exploits CVE-2017-0199 via an OLE2Link object to download a secondary payload. The embedded URL points to a .dOC file, suggesting a further stage of infection. No VBA macros were found to be executable, but the critical heuristic firing indicates a direct exploit attempt.
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 http://103.182.16.23/whttp/4/IOI0ioio0OIOIO0IOI0ioi0i0000000%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%2300000000.dOC
