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 a VBA macro, specifically within an Auto_Close function. This suggests the macro is designed to execute arbitrary commands upon closing the presentation, likely to download and execute a secondary payload. No specific family could be identified, but the technique is common for initial access.
