MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell

The sample is a PowerPoint file containing VBA macros, specifically an Auto_Close macro that executes a shell command. This indicates the file is designed to run malicious code upon opening or closing. The macro likely attempts to download and execute a second-stage payload from the embedded URL. The URL itself was flagged as confirmed benign, but the macro execution is still a high-risk indicator.

Heuristics 4

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.
