The file is identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot variant. The primary attack vector is likely social engineering to convince the user to enable macros, which would then execute a dropper function to download and run a secondary payload. No specific URLs or scripts were extracted, but the heuristic detection is highly indicative of Qbot's typical behavior.
