MITRE ATT&CK
T1059.005 Visual Basic
T1204.002 Malicious File
T1566.001 Spearphishing Attachment
The sample contains VBA macros, including a Document_Open auto-execution macro, which is a common technique for initiating malicious actions. The script appears to be designed to download and execute a second-stage payload, as indicated by the CreateObject calls and the ClamAV detection as a downloader. The obfuscated nature of the script prevents a more detailed analysis of its specific actions.
