MITRE ATT&CK
T1204.002 Malicious File

The file is an Excel spreadsheet identified by ClamAV as Xls.Dropper.QbotDocu12020-9818439-0, indicating it functions as a dropper for the Qbot malware. The primary attack vector is likely social engineering to convince the user to enable macros, which would then execute malicious code to download and run a secondary payload. The presence of Qbot indicators strongly suggests this malicious intent.
