T1059.005 Visual Basic
T1059.001 PowerShell
The file contains VBA macros that utilize the Shell() function, indicating an attempt to execute external commands. The document body presents a fake financial statement, likely to trick the user into enabling macros. The presence of ClamAV detections for 'Doc.Trojan.Marker' further supports its malicious nature. The extracted artifact 'macros.bas' is a VBA macro, and the heuristic 'OLE_VBA_SHELL' confirms the use of Shell() for execution.
