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

The sample contains a VBA macro that executes automatically when the document is opened, as indicated by the 'Document_Open' subroutine. This macro constructs the URL 'kukumar1s.ru/doc' and attempts to open a password-protected document. The macro's intent is to lure the user into opening a secondary, password-protected document, likely for malicious purposes.
