MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell

The sample is a PowerPoint file containing VBA macros. The Auto_Close macro is configured to execute a shell command, indicating it's designed to download and execute a second-stage payload. The presence of a Shell() call and VBA p-code auto-execution further supports this. While a URL was extracted, it was confirmed as benign, suggesting the malicious payload URL might be dynamically generated or obfuscated within the VBA code.

Heuristics 5

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
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.
