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_SHELLShell() call in VBA
-
Auto_Open macro high OLE_VBA_AUTOAuto_Open macro
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled 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_TRIAGEOne 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_MACROSDocument contains VBA macro code
