The sample is a PowerPoint file containing a VBA macro with an Auto_Close subroutine. This subroutine calls the Shell function to execute a command. The command is constructed by concatenating two strings, resulting in the URL 'https://bitbucket.org/!api/2.0/snippets/rikimartinplace/EgdXdp/32cdae6d07e209887267fe32217e8f7baf9a6585/files/olafinal1'. This URL is likely used to download and execute a second-stage payload. The heuristic firing for mshta.exe suggests the execution of downloaded content.

Heuristics 5

  • 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.
  • 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.
