MITRE ATT&CK

The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot variant designed to act as a dropper. The primary function is likely to download and execute a secondary payload, a common tactic for Qbot. No VBA or scripts were extracted, but the heuristic is sufficient for attribution.
