MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious File T1059.005 Command and Scripting Interpreter: Visual Basic

The critical heuristic firing indicates exploitation of CVE-2017-0199, which is a known vulnerability used to download and execute remote code. The embedded URL, 'https://givenbestthingswithgreatenssgifromthegodtogivemebestthignswithgreans.business@acessaurl.com/t4AiJaq', is the likely source of the secondary payload. No VBA macros were found to contain executable statements, suggesting the exploit relies solely on the OLE vulnerability.

Heuristics 2

  • OLE2Link / URL Moniker → remote loader — CVE-2017-0199 critical CVE likely CVE_2017_0199
    Document 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.
    URL https://givenbestthingswithgreatenssgifromthegodtogivemebestthignswithgreans.business@acessaurl.com/t4AiJaq
  • VBA project contains no executable statements low OLE_VBA_MACROS
