MITRE ATT&CK
T1059.005 Visual Basic

This PowerPoint file contains heavily obfuscated VBA macros, including an Auto_Close function, designed to execute arbitrary code using the Shell() function. The script attempts to decode and run a payload, likely a second-stage downloader or malware. The ClamAV detection name 'Ppt.Malware.Sload-9785240-0' further supports its malicious nature.

Heuristics 6

  • Shell() call in VBA critical OLE_VBA_SHELL
    Shell() call in VBA
  • Obfuscated auto-exec VBA loader critical OLE_VBA_OBFUSCATED_AUTOEXEC_LOADER
    Auto-exec VBA reconstructs strings with a heavy custom decoder (numeric char-array, repeated hex-string decode, or junk-token Replace removal) and feeds them to a COM-instantiation or execution sink. This obfuscated-loader shape keeps CreateObject/Shell/URL indicators out of the macro source.
  • ClamAV: Ppt.Malware.Sload-9785240-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Ppt.Malware.Sload-9785240-0
  • 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
