MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1059.003 Windows Command Shell T1204.002 Malicious File

The file is an OOXML document containing VBA macros. Heuristics indicate the VBA code references PowerShell and cmd.exe, and uses GetObject. The VBA code itself appears to be heavily obfuscated, but its structure suggests it is designed to execute further commands, likely downloading and executing a second-stage payload. The presence of these indicators strongly suggests a malicious intent, likely for payload delivery.
