MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The sample contains VBA macros, including an AutoOpen macro, which is a common delivery mechanism for malware. Heuristics indicate the use of WinExec and cmd.exe, suggesting the execution of external commands. The CVE-2012-0158 heuristic points to a specific vulnerability exploitation. The VBA code likely downloads and executes a second-stage payload, although the exact nature of the payload is not discernible from the provided information.

VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
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.
