MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The file is an Excel document identified by ClamAV as 'Xls.Dropper.QbotDocu12020-9818439-0', strongly suggesting it is a Qbot variant. The primary attack pattern involves tricking the user into enabling macros, which would then likely download and execute a secondary payload. No VBA scripts or document body text were extracted, but the ClamAV detection is highly indicative of Qbot's typical dropper behavior.
