MITRE ATT&CK

T1547.001 Registry Run Keys / Startup Folder T1547.001 Registry Run Keys / Startup Folder T1059.005 Visual Basic

The sample contains VBA macros, including an Auto_Open macro, which is a strong indicator of malicious intent. The script attempts to save a copy of itself as 'mypersonnel.xls' into the Excel startup directory, indicating an attempt to establish persistence. The document body, presented as a form for 'Eurofins-SKHĐ', is likely a lure to trick users into opening and interacting with the malicious macro.
