MITRE ATT&CK

The file is an Excel spreadsheet identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly indicating a Qbot variant. The primary attack vector is likely social engineering to enable macros, which would then execute a dropper function to download and execute a secondary payload. The detection name itself suggests a dropper functionality.
