MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The file is a PowerPoint presentation containing VBA macros. A critical heuristic firing indicates the use of the Shell() function within an Auto_Close macro, which is a common technique for executing arbitrary commands. This suggests the macro is designed to download and execute a secondary payload upon closing the presentation. No specific family could be identified, and no external IOCs were extracted.
