MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample is a Microsoft Office document containing VBA macros, specifically a Document_Open macro that executes upon opening. Heuristics indicate the use of CreateObject and GetObject, common for downloading and executing payloads. The ClamAV detection explicitly names Emotet, a known malware family that frequently uses this infection vector. The VBA macro itself is heavily obfuscated but its presence and the associated heuristics strongly suggest it's designed to download and execute a second-stage payload.
