MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is a malicious Office document containing VBA macros, specifically a Document_Open macro designed to execute code upon opening. The macro attempts to overwrite its own code with a string literal 'APMPKILL', likely as part of a payload delivery or obfuscation mechanism. This indicates a macro-based downloader attack pattern.
