MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.001 PowerShell

The file contains a critical ClamAV detection for Doc.Exploit.DDEautoexec, indicating a known malware signature. The document body explicitly uses DDE to execute 'powershell.exe' with 'calc.exe' as an argument, demonstrating exploitation for client execution.
