T1059.005 Visual Basic for Applications
T1204.002 Malicious File
The file contains Excel 4.0 macros, specifically an Auto_Open function, which is a strong indicator of malicious intent. The heuristics indicate the use of ShellExecute and dangerous XLM functions, suggesting the macro is designed to download and execute a secondary payload. The embedded URL points to a GIF file, which is often used as a lure or a staging point for malware delivery. The ClamAV detection name 'Doc.Downloader' further supports this assessment.
