MITRE ATT&CK

T1059.005 Visual Basic for Applications T1566.001 Spearphishing Attachment

The file is an Office document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. ClamAV detections indicate it is a known malicious document, likely a Trojan. The document body discusses urbanism and public space, which appears to be a lure to encourage macro execution. The presence of a Document_Open macro strongly suggests the intent is to automatically run malicious code upon opening the document, likely to download a second-stage payload.
