MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The file contains VBA macros, including CreateObject and CallByName calls, which are indicative of malicious activity. The ClamAV detection 'Doc.Downloader.Powdow-7643936-0' strongly suggests a downloader functionality. The embedded script, though obfuscated, likely facilitates the download and execution of a second-stage payload, aligning with the downloader pattern.
