MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment T1105 Ingress Tool Transfer

The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly indicating it functions as a dropper for the Qbot malware family. The presence of macro-related heuristics suggests it likely uses embedded VBA to download and execute a secondary payload, a common tactic for Qbot distribution. This malicious behavior is consistent with spearphishing attachment delivery methods.
