MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File T1105 Ingress Tool Transfer

The file is a malicious Excel spreadsheet containing VBA macros. The macros execute a PowerShell command that downloads an executable from 'weeshoppi.com' and then runs it. This indicates a downloader or droppper functionality, aiming to fetch and execute a second-stage payload. The presence of a PowerShell command and a download URL strongly suggests this attack pattern.
