MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The file is an Office document containing VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening. ClamAV detections 'Doc.Trojan.Walker-6' further confirm its malicious nature. The document body presents seemingly innocuous information about election dates and voting centers, acting as a lure to encourage users to enable macros. No specific malware family could be identified, but the presence of a Document_Open macro suggests an attempt to download and execute a second-stage payload.
