MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell

The critical heuristic 'OLE_VBA_SHELL' indicates the presence of a Shell() call within the VBA macros. This is further supported by the 'OLE_VBA_PCODE_AUTOEXEC_EXEC' heuristic, which flags auto-execution with execution tokens. The Auto_Close macro is also present, suggesting it is designed to execute automatically when the presentation is closed. These factors strongly suggest the macro is intended to download and execute a second-stage payload. No specific family could be identified, and no external IOCs were extracted.
