MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The file was detected by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', which strongly suggests it is a Qbot variant designed to download and execute a secondary payload. The presence of macro-related heuristics further supports its role as a dropper. The file's metadata indicates it is an older Excel document, potentially used for initial infection vectors.
