MITRE ATT&CK
T1059.005 Visual Basic for Applications
T1566.002 Spearphishing with Other Malicious Documents
The file is an Excel spreadsheet containing VBA macros, specifically an Auto_Open macro, which is a common technique for executing malicious code upon opening. ClamAV detections indicate it is a known trojan. The document body contains what appears to be event planning details, likely a lure to encourage the user to enable macros. No scripts were extracted, but the presence of an Auto_Open macro strongly suggests the intent is to execute malicious code.
