MITRE ATT&CK
T1059.001 PowerShell T1218.005 System Binary Proxy Execution: Mshta

The file contains VBA macros, specifically an Auto_Close macro, which is a common technique for executing malicious code upon document closure. Heuristics indicate the use of mshta.exe and general command execution, suggesting the macro is designed to download and execute a secondary payload. The presence of an embedded URL, though benign in this instance, further supports a delivery mechanism. No specific family could be identified.

Heuristics 6

  • Reference to mshta.exe high SC_STR_MSHTA
    Reference to mshta.exe
  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
  • 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.
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • 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://www.j.mp/hwdiwdjwdhdijsllal
    • http://www.google.com
