MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The sample contains a VBA macro within the Document_Open subroutine, which is designed to execute automatically when the document is opened. This macro attempts to overwrite itself with its own code and then save the document, likely to facilitate the execution of a malicious payload. The presence of the 'APMPKILL' comment and the heuristic firings strongly suggest malicious intent.
