The sample is a PowerPoint file containing VBA macros, specifically an Auto_Close macro that is triggered when the presentation is closed. The presence of GetObject calls and ShellExecute API references indicates that the macro is designed to execute arbitrary code. The Auto_Close macro is likely used to download and execute a second-stage payload, a common technique for initial access.

Reference to ShellExecute API high SC_STR_SHELLEXECReference to ShellExecute API
-
Auto_Close macro high OLE_VBA_AUTOCLOSEAuto_Close macro
-
GetObject call high OLE_VBA_GETOBJGetObject call
-
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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
Suspicious extracted artifact medium 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.
