MITRE ATT&CK
T1059.005 Visual Basic T1059.001 PowerShell

The sample is a PowerPoint file containing a malicious VBA macro. The 'Auto_Open' function is present, indicating that the macro will execute automatically when the presentation is opened. A critical heuristic firing indicates the use of the 'Shell()' function within the VBA code, which is commonly used to execute arbitrary commands or download and run additional payloads. No specific malware family could be identified, and no external IOCs were extracted from the sample.

Heuristics 5

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • Auto_Open macro high OLE_VBA_AUTO
    Auto_Open 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.
  • Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code

Extracted artifacts 1
