MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

This PowerPoint file contains VBA macros, specifically an Auto_Close macro that is triggered when the presentation is closed. The heuristic 'OLE_VBA_PCODE_AUTOEXEC_EXEC' indicates that this macro uses GetObject for execution. This pattern suggests the macro is designed to download and execute a second-stage payload from a remote source. No specific family could be identified, and no external IOCs were extracted.
