MITRE ATT&CK

T1059.001 PowerShell

The sample is a PowerPoint file containing a VBA macro with an Auto_Open procedure. This macro utilizes GetObject and references PowerShell, indicating an attempt to execute commands. The presence of an embedded URL, though benign, suggests a potential delivery vector. The macro's primary function appears to be launching PowerShell, likely to download and execute a secondary payload.

Heuristics 6

Reference to PowerShell high SC_STR_POWERSHELL

Reference to PowerShell
Auto_Open macro high OLE_VBA_AUTO

Auto_Open macro
GetObject call high OLE_VBA_GETOBJ

GetObject call
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.
