MITRE ATT&CK

T1059.005 Visual Basic T1203 Exploitation for Client Execution

The sample contains VBA macros that leverage Auto_Close and CreateObject to execute a script. This script constructs the string "WScript.Shell" and then calls its Exec method with a URL that appears to be a shortened link, likely to download and execute a second-stage payload. The presence of Auto_Close and CreateObject, along with references to ShellExecute and WScript, strongly indicates a dropper functionality.
