T1059.001 PowerShell
T1204.002 Malicious File
The sample contains Excel 4.0 macros, specifically an Auto_Open macro, which is a critical finding. The macro executes a PowerShell command to download a file named 'vj.exe' from 'https://cutt.ly/mggM8iA'. It then moves the downloaded file to the user's AppData directory and executes it. This indicates a downloader or droppper functionality.
