MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell

The file contains VBA macros, including an Auto_Close macro, which is designed to execute code when the presentation is closed. The critical heuristic firing indicates a Shell() call within the VBA code, suggesting the macro attempts to run an external command. This is likely used to download and execute a second-stage payload. The embedded URL, although marked as confirmed benign, is included as a potential IOC.

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.

URL http://%40%40%40@j.mp/sghaj67agsh
