MITRE ATT&CK

T1059.005 Visual Basic for Applications T1059.001 PowerShell

The sample is a malicious PowerPoint file containing VBA macros. The presence of an Auto_Close macro and a Shell() call strongly indicates that the macros are designed to execute arbitrary code. The ClamAV detection 'Doc.Malware.Valyria-10008083-0' further confirms its malicious nature. The VBA macros likely download and execute a second-stage payload.
