MITRE ATT&CK
T1204.002 Malicious File Execution: Malicious File
T1059.001 Command and Scripting Interpreter: PowerShell
The sample is an OLE file that triggers the CVE-2017-0199 vulnerability. This vulnerability allows the file to act as a remote loader, fetching and executing a secondary payload from the embedded URL http://94.156.253.236/HTMLcvdesiii.dOC. The file's structure and the specific heuristic firing strongly indicate its use as a downloader for further malicious activity.
Heuristics 2
-
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.
