MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File

The sample is a malicious Excel file identified by the 'OLE_VBA_MACROS' and 'OLE_VBA_AUTO' heuristics, indicating the presence of an Auto_Open macro. This macro likely executes malicious code upon opening the document. The embedded URL 'http://betterwebspacetest.com/pm/setup.msi' is highly suspicious and is likely used to download and execute a second-stage payload, such as an MSI installer.

Heuristics 3

  • Auto_Open macro high OLE_VBA_AUTO
    Auto_Open macro
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
    One 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://betterwebspacetest.com/pm/setup.msi
    • http://www.w3.org/1999/XSL/Transform
